		31
		32	=head3 My question isn't answered here, can I ask a human?
		33
		34	Before sending me mail, you could go to IRC: C<irc.freenode.net>,
		35	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
		36	interested in learning about new and exciting problems (but not FAQs :).
		37
		38	=head3 I use Gentoo, and I have a problem...
		39
		40	There are three big problems with Gentoo Linux: first of all, most if not
		41	all Gentoo systems are completely broken (missing or mismatched header
		42	files, broken compiler etc. are just the tip of the iceberg); secondly,
		43	the Gentoo maintainer thinks it is a good idea to add broken patches to
		44	the code; and lastly, it should be called Gentoo GNU/Linux.
		45
		46	For these reasons, it is impossible to support rxvt-unicode on
		47	Gentoo. Problems appearing on Gentoo systems will usually simply be
		48	ignored unless they can be reproduced on non-Gentoo systems.
		49
		50	=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
		51
		52	Beginning with version 7.3, there is a perl extension that implements a
		53	simple tabbed terminal. It is installed by default, so any of these should
		54	give you tabs:
		55
		56	@@URXVT_NAME@@ -pe tabbed
		57
		58	URxvt.perl-ext-common: default,tabbed
		59
		60	It will also work fine with tabbing functionality of many window managers
		61	or similar tabbing programs, and its embedding-features allow it to be
		62	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
		63	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
		64	(murxvt) terminal as an example embedding application.

33		72
34	=item I am using Debian GNU/Linux and have a problem...
35
36	The Debian GNU/Linux package of rxvt-unicode contains large patches that
37	considerably change the behaviour of rxvt-unicode. Before reporting a
38	bug to the original rxvt-unicode author please download and install the
39	genuine version (L<http://software.schmorp.de#rxvt-unicode>) and try to
40	reproduce the problem. If you cannot, chances are that the problems are
41	specific to Debian GNU/Linux, in which case it should be reported via the
42	Debian Bug Tracking System (use C<reportbug> to report the bug).
43
44	For other problems that also affect the Debian package, you can and
45	probably should use the Debian BTS, too, because, after all, it's also a
46	bug in the Debian version and it serves as a reminder for other users that
47	might encounter the same issue.
48
49	=item When I log-in to another system it tells me about missing terminfo data?
50
51	The terminal description used by rxvt-unicode is not as widely available
52	as that for xterm, or even rxvt (for which the same problem often arises).
53
54	The correct solution for this problem is to install the terminfo, this can
55	be done like this (with ncurses' infocmp):
56
57	REMOTE=remotesystem.domain
58	infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
59
60	... or by installing rxvt-unicode normally on the remote system,
61
62	If you cannot or do not want to do this, then you can simply set
63	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
64	problems arising, which includes wrong keymapping, less and different
65	colours and some refresh errors in fullscreen applications. It's a nice
66	quick-and-dirty workaround for rare cases, though.
67
68	If you always want to do this (and are fine with the consequences) you
69	can either recompile rxvt-unicode with the desired TERM value or use a
70	resource to set it:
71
72	URxvt.termName: rxvt
73
74	If you don't plan to use B<rxvt> (quite common...) you could also replace
75	the rxvt terminfo file with the rxvt-unicode one.
76
77	=item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
78
79	=item I need a termcap file entry.
80
81	One reason you might want this is that some distributions or operating
82	systems still compile some programs using the long-obsoleted termcap
83	library (Fedora Core's bash is one example) and rely on a termcap entry
84	for C<rxvt-unicode>.
85
86	You could use rxvt's termcap entry with resonable results in many cases.
87	You can also create a termcap entry by using terminfo's infocmp program
88	like this:
89
90	infocmp -C rxvt-unicode
91
92	Or you could use this termcap entry, generated by the command above:
93

114
115	=item Why does C<ls> no longer have coloured output?
116
117	The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
118	decide wether a terminal has colour, but uses it's own configuration
119	file. Needless to say, C<rxvt-unicode> is not in it's default file (among
120	with most other terminals supporting colour). Either add:
121
122	TERM rxvt-unicode
123
124	to C</etc/DIR_COLORS> or simply add:
125
126	alias ls='ls --color=auto'
127
128	to your C<.profile> or C<.bashrc>.
129
130	=item Why doesn't vim/emacs etc. use the 88 colour mode?
131
132	=item Why doesn't vim/emacs etc. make use of italic?
133
134	=item Why are the secondary screen-related options not working properly?
135
136	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
137	distributions (most notably Debian GNU/Linux) break rxvt-unicode
138	by setting C<TERM> to C<rxvt>, which doesn't have these extra
139	features. Unfortunately, some of these (most notably, again, Debian
140	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
141	file, so you will need to install it on your own (See the question B<When
142	I log-in to another system it tells me about missing terminfo data?> on
143	how to do this).
144
145	=item My numerical keypad acts weird and generates differing output?
146
147	Some Debian GNUL/Linux users seem to have this problem, although no
148	specific details were reported so far. It is possible that this is caused
149	by the wrong C<TERM> setting, although the details of wether and how
150	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
151	keymap. See the answer to the previous question, and please report if that
152	helped.
153
154	=item Rxvt-unicode does not seem to understand the selected encoding?
155
156	=item Unicode does not seem to work?
157
158	If you encounter strange problems like typing an accented character but
159	getting two unrelated other characters or similar, or if program output is
160	subtly garbled, then you should check your locale settings.
161
162	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
163	programs. Often rxvt-unicode is started in the C<C> locale, while the
164	login script running within the rxvt-unicode window changes the locale to
165	something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
166
167	The best thing is to fix your startup environment, as you will likely run
168	into other problems. If nothing works you can try this in your .profile.
169
170	printf '\e]701;%s\007' "$LC_CTYPE"
171
172	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
173	supported on your systems. Some systems have a C<locale> command which
174	displays this (also, C<perl -e0> can be used to check locale settings, as
175	it will complain loudly if it cannot set the locale). If it displays something
176	like:
177
178	locale: Cannot set LC_CTYPE to default locale: ...
179
180	Then the locale you specified is not supported on your system.
181
182	If nothing works and you are sure that everything is set correctly then
183	you will need to remember a little known fact: Some programs just don't
184	support locales :(
185
186	=item Why do some characters look so much different than others?
187
188	=item How does rxvt-unicode choose fonts?
189
190	Most fonts do not contain the full range of Unicode, which is
191	fine. Chances are that the font you (or the admin/package maintainer of
192	your system/os) have specified does not cover all the characters you want
193	to display.
194
195	B<rxvt-unicode> makes a best-effort try at finding a replacement
196	font. Often the result is fine, but sometimes the chosen font looks
197	bad/ugly/wrong. Some fonts have totally strange characters that don't
198	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
199	intelligence to detect that a specific glyph is wrong: it has to believe
200	the font that the characters it claims to contain indeed look correct.
201
202	In that case, select a font of your taste and add it to the font list,
203	e.g.:
204
205	@@RXVT_NAME@@ -fn basefont,font2,font3...
206
207	When rxvt-unicode sees a character, it will first look at the base
208	font. If the base font does not contain the character, it will go to the
209	next font, and so on. Specifying your own fonts will also speed up this
210	search and use less resources within rxvt-unicode and the X-server.
211
212	The only limitation is that none of the fonts may be larger than the base
213	font, as the base font defines the terminal character cell size, which
214	must be the same due to the way terminals work.
215
216	=item Why do some chinese characters look so different than others?
217
218	This is because there is a difference between script and language --
219	rxvt-unicode does not know which language the text that is output is,
220	as it only knows the unicode character codes. If rxvt-unicode first
221	sees a japanese/chinese character, it might choose a japanese font for
222	display. Subsequent japanese characters will use that font. Now, many
223	chinese characters aren't represented in japanese fonts, so when the first
224	non-japanese character comes up, rxvt-unicode will look for a chinese font
225	-- unfortunately at this point, it will still use the japanese font for
226	chinese characters that are also in the japanese font.
227
228	The workaround is easy: just tag a chinese font at the end of your font
229	list (see the previous question). The key is to view the font list as
230	a preference list: If you expect more japanese, list a japanese font
231	first. If you expect more chinese, put a chinese font first.
232
233	In the future it might be possible to switch language preferences at
234	runtime (the internal data structure has no problem with using different
235	fonts for the same character at the same time, but no interface for this
236	has been designed yet).
237
238	Until then, you might get away with switching fonts at runtime (see L<Can
239	I switch the fonts at runtime?> later in this document).
240
241	=item Why does rxvt-unicode sometimes leave pixel droppings?
242
243	Most fonts were not designed for terminal use, which means that character
244	size varies a lot. A font that is otherwise fine for terminal use might
245	contain some characters that are simply too wide. Rxvt-unicode will avoid
246	these characters. For characters that are just "a bit" too wide a special
247	"careful" rendering mode is used that redraws adjacent characters.
248
249	All of this requires that fonts do not lie about character sizes,
250	however: Xft fonts often draw glyphs larger than their acclaimed bounding
251	box, and rxvt-unicode has no way of detecting this (the correct way is to
252	ask for the character bounding box, which unfortunately is wrong in these
253	cases).
254
255	It's not clear (to me at least), wether this is a bug in Xft, freetype,
256	or the respective font. If you encounter this problem you might try using
257	the C<-lsp> option to give the font more height. If that doesn't work, you
258	might be forced to use a different font.
259
260	All of this is not a problem when using X11 core fonts, as their bounding
261	box data is correct.
262
263	=item On Solaris 9, many line-drawing characters are too wide.
264
265	Seems to be a known bug, read
266	L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
267	following ugly workaround to get non-double-wide-characters working:
268
269	#define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
270
271	=item My Compose (Multi_key) key is no longer working.
272
273	The most common causes for this are that either your locale is not set
274	correctly, or you specified a B<preeditStyle> that is not supported by
275	your input method. For example, if you specified B<OverTheSpot> and
276	your input method (e.g. the default input method handling Compose keys)
277	does not support this (for instance because it is not visual), then
278	rxvt-unicode will continue without an input method.
279
280	In this case either do not specify a B<preeditStyle> or specify more than
281	one pre-edit style, such as B<OverTheSpot,Root,None>.
282
283	=item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
284
285	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
286	international keyboards) or simply use ISO 14755 support to your
287	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
288	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
289	character and so on.
290
291	=item How can I keep rxvt-unicode from using reverse video so much?
292
293	First of all, make sure you are running with the right terminal settings
294	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
295	make sure you have specified colours for italic and bold, as otherwise
296	rxvt-unicode might use reverse video to simulate the effect:
297
298	URxvt.colorBD: white
299	URxvt.colorIT: green
300
301	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
302
303	For some unexplainable reason, some rare programs assume a very weird
304	colour palette when confronted with a terminal with more than the standard
305	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
306	these programs not to assume non-ISO colours without very good reasons.
307
308	In the meantime, you can either edit your C<rxvt-unicode> terminfo
309	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
310	fix colours but keep you from using other rxvt-unicode features.
311
312	=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
313
314	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
315	in your compile environment, or an implementation that implements it,
316	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
317	B<wchar_t> is represented as unicode.
318
319	As you might have guessed, FreeBSD does neither define this symobl nor
320	does it support it. Instead, it uses it's own internal representation of
321	B<wchar_t>. This is, of course, completely fine with respect to standards.
322
323	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
324	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
325
326	C<__STDC_ISO_10646__> is the only sane way to support multi-language
327	apps in an OS, as using a locale-dependent (and non-standardized)
328	representation of B<wchar_t> makes it impossible to convert between
329	B<wchar_t> (as used by X11 and your applications) and any other encoding
330	without implementing OS-specific-wrappers for each and every locale. There
331	simply are no APIs to convert B<wchar_t> into anything except the current
332	locale encoding.
333
334	Some applications (such as the formidable B<mlterm>) work around this
335	by carrying their own replacement functions for character set handling
336	with them, and either implementing OS-dependent hacks or doing multiple
337	conversions (which is slow and unreliable in case the OS implements
338	encodings slightly different than the terminal emulator).
339
340	The rxvt-unicode author insists that the right way to fix this is in the
341	system libraries once and for all, instead of forcing every app to carry
342	complete replacements for them :)
343
344	=item I use Solaris 9 and it doesn't compile/work/etc.
345
346	Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
347	problems with C<wcwidth> and a compile problem.
348
349	=item How can I use rxvt-unicode under cygwin?
350
351	rxvt-unicode should compile and run out of the box on cygwin, using
352	the X11 libraries that come with cygwin. libW11 emulation is no
353	longer supported (and makes no sense, either, as it only supported a
354	single font). I recommend starting the X-server in C<-multiwindow> or
355	C<-rootless> mode instead, which will result in similar look&feel as the
356	old libW11 emulation.
357
358	At the time of this writing, cygwin didn't seem to support any multi-byte
359	encodings, so you are likely limited to 8-bit encodings.
360
361	=item How does rxvt-unicode determine the encoding to use?
362
363	=item Is there an option to switch encodings?
364
365	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
366	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
367	UTF-8 or any other encodings with respect to terminal I/O.
368
369	The reasons is that there exists a perfectly fine mechanism for selecting
370	the encoding, doing I/O and (most important) communicating this to all
371	applications so everybody agrees on character properties such as width
372	and code number. This mechanism is the I<locale>. Applications not using
373	that info will have problems (for example, C<xterm> gets the width of
374	characters wrong as it uses it's own, locale-independent table under all
375	locales).
376
377	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
378	programs doing the same (that is, most) will automatically agree in the
379	interpretation of characters.
380
381	Unfortunately, there is no system-independent way to select locales, nor
382	is there a standard on how locale specifiers will look like.
383
384	On most systems, the content of the C<LC_CTYPE> environment variable
385	contains an arbitrary string which corresponds to an already-installed
386	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
387	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
388	(i.e. C<de> or C<german>) are also common.
389
390	Rxvt-unicode ignores all other locale categories, and except for
391	the encoding, ignores country or language-specific settings,
392	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
393	rxvt-unicode.
394
395	If you want to use a specific encoding you have to make sure you start
396	rxvt-unicode with the correct C<LC_CTYPE> category.
397
398	=item Can I switch locales at runtime?
399
400	Yes, using an escape sequence. Try something like this, which sets
401	rxvt-unicode's idea of C<LC_CTYPE>.
402
403	printf '\e]701;%s\007' ja_JP.SJIS
404
405	See also the previous answer.
406
407	Sometimes this capability is rather handy when you want to work in
408	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
409	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
410	first switches to a locale supported by xjdic and back later:
411
412	printf '\e]701;%s\007' ja_JP.SJIS
413	xjdic -js
414	printf '\e]701;%s\007' de_DE.UTF-8
415
416	You can also use xterm's C<luit> program, which usually works fine, except
417	for some locales where character width differs between program- and
418	rxvt-unicode-locales.
419
420	=item Can I switch the fonts at runtime?
421
422	Yes, using an escape sequence. Try something like this, which has the same
423	effect as using the C<-fn> switch, and takes effect immediately:
424
425	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
426
427	This is useful if you e.g. work primarily with japanese (and prefer a
428	japanese font), but you have to switch to chinese temporarily, where
429	japanese fonts would only be in your way.
430
431	You can think of this as a kind of manual ISO-2022 switching.
432
433	=item Why do italic characters look as if clipped?
434
435	Many fonts have difficulties with italic characters and hinting. For
436	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
437	Mono> completely fails in it's italic face. A workaround might be to
438	enable freetype autohinting, i.e. like this:
439
440	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
441	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
442
443	=item My input method wants <some encoding> but I want UTF-8, what can I do?
444
445	You can specify separate locales for the input method and the rest of the
446	terminal, using the resource C<imlocale>:
447
448	URxvt*imlocale: ja_JP.EUC-JP
449
450	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
451	use your input method. Please note, however, that you will not be able to
452	input characters outside C<EUC-JP> in a normal way then, as your input
453	method limits you.
454
455	=item Rxvt-unicode crashes when the X Input Method changes or exits.
456
457	Unfortunately, this is unavoidable, as the XIM protocol is racy by
458	design. Applications can avoid some crashes at the expense of memory
459	leaks, and Input Methods can avoid some crashes by careful ordering at
460	exit time. B<kinput2> (and derived input methods) generally succeeds,
461	while B<SCIM> (or similar input methods) fails. In the end, however,
462	crashes cannot be completely avoided even if both sides cooperate.
463
464	So the only workaround is not to kill your Input Method Servers.

		93	=head3 How can I start @@URXVT_NAME@@d automatically when I run @@URXVT_NAME@@c?
		94
		95	If you want to start @@URXVT_NAME@@d automatically whenever you run
		96	@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
		97
		98	#!/bin/sh

		104
		105	This tries to create a new terminal, and if fails with exit status 2,
		106	meaning it couldn't connect to the daemon, it will start the daemon and
		107	re-run the command. Subsequent invocations of the script will re-use the

		109
		110	=head3 How do I distinguish whether I'm running rxvt-unicode or a regular
		111	xterm? I need this to decide about setting colours etc.
		112
		113	The original rxvt and rxvt-unicode always export the variable "COLORTERM",
		114	so you can check and see if that is set. Note that several programs, JED,
		115	slrn, Midnight Commander automatically check this variable to decide
		116	whether or not to use colour.
		117
		118	=head3 How do I set the correct, full IP address for the DISPLAY variable?
		119
		120	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		121	insecure mode then it is possible to use the following shell script
		122	snippets to correctly set the display. If your version of rxvt-unicode
		123	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		124	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		125	regular xterm.

		142
		143	=head3 How do I compile the manual pages on my own?
		144
		145	You need to have a recent version of perl installed as F</usr/bin/perl>,
		146	one that comes with F<pod2man>, F<pod2text> and F<pod2xhtml> (from
		147	F<Pod::Xhtml>). Then go to the doc subdirectory and enter C<make alldoc>.
		148
		149	=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
		150
		151	I often get asked about this, and I think, no, they didn't cause extra
		152	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		153	that the urxvt binary is larger (due to some encoding tables always being
		154	compiled in), but it actually uses less memory (RSS) after startup. Even
		155	with C<--disable-everything>, this comparison is a bit unfair, as many
		156	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		157	already in use in this mode.
		158
		159	text data bss drs rss filename
		160	98398 1664 24 15695 1824 rxvt --disable-everything
		161	188985 9048 66616 18222 1788 urxvt --disable-everything
		162
		163	When you C<--enable-everything> (which I<is> unfair, as this involves xft
		164	and full locale/XIM support which are quite bloaty inside libX11 and my
		165	libc), the two diverge, but not unreasonably so.
		166
		167	text data bss drs rss filename
		168	163431 2152 24 20123 2060 rxvt --enable-everything
		169	1035683 49680 66648 29096 3680 urxvt --enable-everything
		170
		171	The very large size of the text section is explained by the east-asian
		172	encoding tables, which, if unused, take up disk space but nothing else
		173	and can be compiled out unless you rely on X11 core fonts that use those
		174	encodings. The BSS size comes from the 64k emergency buffer that my c++
		175	compiler allocates (but of course doesn't use unless you are out of
		176	memory). Also, using an xft font instead of a core font immediately adds a
		177	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		178	not used.
		179
		180	Of course, due to every character using two or four bytes instead of one,
		181	a large scrollback buffer will ultimately make rxvt-unicode use more
		182	memory.
		183
		184	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		185	still fares rather well. And compared to some monsters like gnome-terminal
		186	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		187	43180k in daemons that stay around after exit, plus half a minute of
		188	startup time, including the hundreds of warnings it spits out), it fares
		189	extremely well *g*.
		190
		191	=head3 Why C++, isn't that unportable/bloated/uncool?
		192
		193	Is this a question? :) It comes up very often. The simple answer is: I had
		194	to write it, and C++ allowed me to write and maintain it in a fraction
		195	of the time and effort (which is a scarce resource for me). Put even
		196	shorter: It simply wouldn't exist without C++.
		197
		198	My personal stance on this is that C++ is less portable than C, but in
		199	the case of rxvt-unicode this hardly matters, as its portability limits
		200	are defined by things like X11, pseudo terminals, locale support and unix
		201	domain sockets, which are all less portable than C++ itself.
		202
		203	Regarding the bloat, see the above question: It's easy to write programs
		204	in C that use gobs of memory, and certainly possible to write programs in
		205	C++ that don't. C++ also often comes with large libraries, but this is
		206	not necessarily the case with GCC. Here is what rxvt links against on my
		207	system with a minimal config:
		208
		209	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		210	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		211	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		212	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		213
		214	And here is rxvt-unicode:
		215
		216	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		217	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		218	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		219	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		220	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		221
		222	No large bloated libraries (of course, none were linked in statically),
		223	except maybe libX11 :)

		226	=head2 Rendering, Font & Look and Feel Issues
		227
		228	=head3 I can't get transparency working, what am I doing wrong?
		229
		230	First of all, transparency isn't officially supported in rxvt-unicode, so
		231	you are mostly on your own. Do not bug the author about it (but you may
		232	bug everybody else). Also, if you can't get it working consider it a rite
		233	of passage: ... and you failed.
		234
		235	Here are four ways to get transparency. B<Do> read the manpage and option
		236	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		237
		238	1. Use transparent mode:
		239
		240	Esetroot wallpaper.jpg
		241	@@URXVT_NAME@@ -tr -tint red -sh 40
		242
		243	That works. If you think it doesn't, you lack transparency and tinting
		244	support, or you are unable to read.
		245	This method requires that the background-setting program sets the
		246	_XROOTPMAP_ID or ESETROOT_PMAP_ID property. Compatible programs
		247	are Esetroot, hsetroot and feh.
		248
		249	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		250	to use effects other than tinting and shading: Just shade/tint/whatever
		251	your picture with gimp or any other tool:
		252
		253	convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
		254	@@URXVT_NAME@@ -pixmap "background.jpg;:root"
		255
		256	That works. If you think it doesn't, you lack GDK-PixBuf support, or you
		257	are unable to read.
		258
		259	3. Use an ARGB visual:
		260
		261	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		262
		263	This requires XFT support, and the support of your X-server. If that
		264	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		265	there yet, no matter what they claim. Rxvt-Unicode contains the necessary
		266	bugfixes and workarounds for Xft and Xlib to make it work, but that
		267	doesn't mean that your WM has the required kludges in place.
		268
		269	4. Use xcompmgr and let it do the job:
		270
		271	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		272	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		273
		274	Then click on a window you want to make transparent. Replace C<0xc0000000>
		275	by other values to change the degree of opacity. If it doesn't work and
		276	your server crashes, you got to keep the pieces.
		277
		278	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		279
		280	Most fonts were not designed for terminal use, which means that character
		281	size varies a lot. A font that is otherwise fine for terminal use might
		282	contain some characters that are simply too wide. Rxvt-unicode will avoid
		283	these characters. For characters that are just "a bit" too wide a special
		284	"careful" rendering mode is used that redraws adjacent characters.
		285
		286	All of this requires that fonts do not lie about character sizes,
		287	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		288	box, and rxvt-unicode has no way of detecting this (the correct way is to
		289	ask for the character bounding box, which unfortunately is wrong in these
		290	cases).
		291
		292	It's not clear (to me at least), whether this is a bug in Xft, freetype,
		293	or the respective font. If you encounter this problem you might try using
		294	the C<-lsp> option to give the font more height. If that doesn't work, you
		295	might be forced to use a different font.
		296
		297	All of this is not a problem when using X11 core fonts, as their bounding
		298	box data is correct.
		299
		300	=head3 How can I keep rxvt-unicode from using reverse video so much?
		301
		302	First of all, make sure you are running with the right terminal settings
		303	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		304	make sure you have specified colours for italic and bold, as otherwise
		305	rxvt-unicode might use reverse video to simulate the effect:
		306
		307	URxvt.colorBD: white
		308	URxvt.colorIT: green
		309
		310	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		311
		312	For some unexplainable reason, some rare programs assume a very weird
		313	colour palette when confronted with a terminal with more than the standard
		314	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		315	these programs not to assume non-ISO colours without very good reasons.
		316
		317	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		318	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		319	fix colours but keep you from using other rxvt-unicode features.
		320
		321	=head3 Can I switch the fonts at runtime?
		322
		323	Yes, using an escape sequence. Try something like this, which has the same
		324	effect as using the C<-fn> switch, and takes effect immediately:
		325
		326	printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
		327
		328	This is useful if you e.g. work primarily with japanese (and prefer a
		329	japanese font), but you have to switch to chinese temporarily, where
		330	japanese fonts would only be in your way.

581		431
		432	Most fonts do not contain the full range of Unicode, which is
		433	fine. Chances are that the font you (or the admin/package maintainer of
		434	your system/os) have specified does not cover all the characters you want
		435	to display.
		436
		437	B<rxvt-unicode> makes a best-effort try at finding a replacement
		438	font. Often the result is fine, but sometimes the chosen font looks
		439	bad/ugly/wrong. Some fonts have totally strange characters that don't
		440	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		441	intelligence to detect that a specific glyph is wrong: it has to believe
		442	the font that the characters it claims to contain indeed look correct.
		443
		444	In that case, select a font of your taste and add it to the font list,
		445	e.g.:
		446
		447	@@URXVT_NAME@@ -fn basefont,font2,font3...
		448
		449	When rxvt-unicode sees a character, it will first look at the base
		450	font. If the base font does not contain the character, it will go to the
		451	next font, and so on. Specifying your own fonts will also speed up this
		452	search and use less resources within rxvt-unicode and the X-server.
		453
		454	The only limitation is that none of the fonts may be larger than the base
		455	font, as the base font defines the terminal character cell size, which
		456	must be the same due to the way terminals work.
		457
		458	=head3 Why do some chinese characters look so different than others?
		459
		460	This is because there is a difference between script and language --
		461	rxvt-unicode does not know which language the text that is output is,
		462	as it only knows the unicode character codes. If rxvt-unicode first
		463	sees a japanese/chinese character, it might choose a japanese font for
		464	display. Subsequent japanese characters will use that font. Now, many
		465	chinese characters aren't represented in japanese fonts, so when the first
		466	non-japanese character comes up, rxvt-unicode will look for a chinese font
		467	-- unfortunately at this point, it will still use the japanese font for
		468	chinese characters that are also in the japanese font.
		469
		470	The workaround is easy: just tag a chinese font at the end of your font
		471	list (see the previous question). The key is to view the font list as
		472	a preference list: If you expect more japanese, list a japanese font
		473	first. If you expect more chinese, put a chinese font first.
		474
		475	In the future it might be possible to switch language preferences at
		476	runtime (the internal data structure has no problem with using different
		477	fonts for the same character at the same time, but no interface for this
		478	has been designed yet).
		479
		480	Until then, you might get away with switching fonts at runtime (see L<Can
		481	I switch the fonts at runtime?> later in this document).

		491
		492	=head3 The new selection selects pieces that are too big, how can I select single words?
		493
		494	If you want to select e.g. alphanumeric words, you can use the following
		495	setting:
		496
		497	URxvt.selection.pattern-0: ([[:word:]]+)
		498
		499	If you click more than twice, the selection will be extended
		500	more and more.
		501
		502	To get a selection that is very similar to the old code, try this pattern:
		503
		504	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		505
		506	Please also note that the I<LeftClick Shift-LeftClick> combination also
		507	selects words like the old code.
		508
		509	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		510
		511	You can disable the perl extension completely by setting the
		512	B<perl-ext-common> resource to the empty string, which also keeps
		513	rxvt-unicode from initialising perl, saving memory.
		514
		515	If you only want to disable specific features, you first have to
		516	identify which perl extension is responsible. For this, read the section
		517	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		518	example, to disable the B<selection-popup> and B<option-popup>, specify
		519	this B<perl-ext-common> resource:
		520
		521	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		522
		523	This will keep the default extensions, but disable the two popup
		524	extensions. Some extensions can also be configured, for example,
		525	scrollback search mode is triggered by B<M-s>. You can move it to any
		526	other combination either by setting the B<searchable-scrollback> resource:
		527

		529
		530	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
		531
		532	See next entry.
		533
		534	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		535
		536	These are caused by the C<readline> perl extension. Under normal
		537	circumstances, it will move your cursor around when you click into the
		538	line that contains it. It tries hard not to do this at the wrong moment,
		539	but when running a program that doesn't parse cursor movements or in some
		540	cases during rlogin sessions, it fails to detect this properly.
		541
		542	You can permanently switch this feature off by disabling the C<readline>
		543	extension:
		544
		545	URxvt.perl-ext-common: default,-readline
		546
		547	=head3 My numerical keypad acts weird and generates differing output?
		548
		549	Some Debian GNUL/Linux users seem to have this problem, although no
		550	specific details were reported so far. It is possible that this is caused
		551	by the wrong C<TERM> setting, although the details of whether and how
		552	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		553	keymap. See the answer to the previous question, and please report if that
		554	helped.
		555
		556	=head3 My Compose (Multi_key) key is no longer working.
		557
		558	The most common causes for this are that either your locale is not set
		559	correctly, or you specified a B<preeditStyle> that is not supported by
		560	your input method. For example, if you specified B<OverTheSpot> and
		561	your input method (e.g. the default input method handling Compose keys)
		562	does not support this (for instance because it is not visual), then
		563	rxvt-unicode will continue without an input method.
		564
		565	In this case either do not specify a B<preeditStyle> or specify more than
		566	one pre-edit style, such as B<OverTheSpot,Root,None>.
		567
		568	If it still doesn't work, then maybe your input method doesn't support
		569	compose sequences - to fall back to the built-in one, make sure you don't
		570	specify an input method via C<-im> or C<XMODIFIERS>.
		571
		572	=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		573
		574	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		575	international keyboards) or simply use ISO 14755 support to your
		576	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		577	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		578	character and so on.
		579
		580	=head3 Mouse cut/paste suddenly no longer works.
		581
		582	Make sure that mouse reporting is actually turned off since killing

		585	quick check is to see if cut/paste works when the Alt or Shift keys are
		586	pressed.

		764	urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		765
		766	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		767	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		768	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		769	font (different glyphs for C<;> and many other harmless characters),
		770	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		771	bold version has less chars than the medium version, so I use it for rare
		772	characters, too. When editing sources with vim, I use italic for comments
		773	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		774
		775	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		776	purposes, it works, and gives a different look, as my normal (Non-bold)
		777	font is already bold, and I want to see a difference between bold and
		778	normal fonts.
		779
		780	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		781	class name. That is because I use different configs for different purposes,
		782	for example, my IRC window is started with C<-name IRC>, and uses these
		783	defaults:
		784
		785	IRC*title: IRC
		786	IRC*geometry: 87x12+535+542

		793	IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
		794
		795	C<Alt-Ctrl-1> and C<Alt-Ctrl-2> switch between two different font
		796	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		797	stuff while keeping a very small window. If somebody pastes something
		798	complicated (e.g. japanese), I temporarily switch to a larger font.
		799
		800	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		801	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		802	file for different hosts, for example, on my main desktop, I use:
		803
		804	URxvt.keysym.C-M-q: command:\033[3;5;5t
		805	URxvt.keysym.C-M-y: command:\033[3;5;606t
		806	URxvt.keysym.C-M-e: command:\033[3;1605;5t
		807	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		808	URxvt.keysym.C-M-p: perl:test
		809
		810	The first for keysym definitions allow me to quickly bring some windows
		811	in the layout I like most. Ion users might start laughing but will stop
		812	immediately when I tell them that I use my own Fvwm2 module for much the
		813	same effect as Ion provides, and I only very rarely use the above key
		814	combinations :->
		815
		816	=head3 Why doesn't rxvt-unicode read my resources?
		817
		818	Well, why, indeed? It does, in a way very similar to other X
		819	applications. Most importantly, this means that if you or your OS loads
		820	resources into the X display (the right way to do it), rxvt-unicode will
		821	ignore any resource files in your home directory. It will only read
		822	F<$HOME/.Xdefaults> when no resources are attached to the display.
		823
		824	If you have or use an F<$HOME/.Xresources> file, chances are that
		825	resources are loaded into your X-server. In this case, you have to
		826	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		827
		828	Also consider the form resources have to use:
		829
		830	URxvt.resource: value
		831
		832	If you want to use another form (there are lots of different ways of
		833	specifying resources), make sure you understand whether and why it
		834	works. If unsure, use the form above.
		835
		836	=head3 When I log-in to another system it tells me about missing terminfo data?
		837
		838	The terminal description used by rxvt-unicode is not as widely available
		839	as that for xterm, or even rxvt (for which the same problem often arises).
		840
		841	The correct solution for this problem is to install the terminfo, this can
		842	be done by simply installing rxvt-unicode on the remote system as well
		843	(in case you have a nice package manager ready), or you can install the
		844	terminfo database manually like this (with ncurses infocmp. works as
		845	user and root):
		846
		847	REMOTE=remotesystem.domain
		848	infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
		849
		850	One some systems you might need to set C<$TERMINFO> to the full path of
		851	F<$HOME/.terminfo> for this to work. Debian systems have a broken tic
		852	which will not be able to overwrite the existing rxvt-unicode terminfo
		853	entry - you might have to manually delete all traces of F<rxvt-unicode*>
		854	from F</etc/terminfo>.
		855
		856	If you cannot or do not want to do this, then you can simply set
		857	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		858	problems arising, which includes wrong keymapping, less and different
		859	colours and some refresh errors in fullscreen applications. It's a nice
		860	quick-and-dirty workaround for rare cases, though.
		861
		862	If you always want to do this (and are fine with the consequences) you
		863	can either recompile rxvt-unicode with the desired TERM value or use a
		864	resource to set it:
		865
		866	URxvt.termName: rxvt
		867
		868	If you don't plan to use B<rxvt> (quite common...) you could also replace
		869	the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
		870
		871	=head3 nano fails with "Error opening terminal: rxvt-unicode"
		872
		873	This exceptionally confusing and useless error message is printed by nano
		874	when it can't find the terminfo database. Nothing is wrong with your
		875	terminal, read the previous answer for a solution.
		876
		877	=head3 C<tic> outputs some error when compiling the terminfo entry.
		878
		879	Most likely it's the empty definition for C<enacs=>. Just replace it by
		880	C<enacs=\E[0@> and try again.
		881
		882	=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
		883
		884	See next entry.
		885
		886	=head3 I need a termcap file entry.
		887
		888	One reason you might want this is that some distributions or operating
		889	systems still compile some programs using the long-obsoleted termcap
		890	library (Fedora Core's bash is one example) and rely on a termcap entry
		891	for C<rxvt-unicode>.
		892
		893	You could use rxvt's termcap entry with reasonable results in many cases.
		894	You can also create a termcap entry by using terminfo's infocmp program
		895	like this:
		896
		897	infocmp -C rxvt-unicode
		898
		899	Or you could use the termcap entry in doc/etc/rxvt-unicode.termcap,
		900	generated by the command above.
		901
		902	=head3 Why does C<ls> no longer have coloured output?
		903
		904	The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
		905	decide whether a terminal has colour, but uses its own configuration
		906	file. Needless to say, C<rxvt-unicode> is not in its default file (among
		907	with most other terminals supporting colour). Either add:
		908
		909	TERM rxvt-unicode
		910
		911	to C</etc/DIR_COLORS> or simply add:
		912
		913	alias ls='ls --color=auto'
		914
		915	to your C<.profile> or C<.bashrc>.
		916
		917	=head3 Why doesn't vim/emacs etc. use the 88 colour mode?
		918
		919	See next entry.
		920
		921	=head3 Why doesn't vim/emacs etc. make use of italic?
		922
		923	See next entry.
		924
		925	=head3 Why are the secondary screen-related options not working properly?
		926
		927	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		928	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		929	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		930	features. Unfortunately, some of these (most notably, again, Debian
		931	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		932	file, so you will need to install it on your own (See the question B<When
		933	I log-in to another system it tells me about missing terminfo data?> on
		934	how to do this).
		935
		936
		937	=head2 Encoding / Locale / Input Method Issues
		938
		939	=head3 Rxvt-unicode does not seem to understand the selected encoding?
		940
		941	See next entry.
		942
		943	=head3 Unicode does not seem to work?
		944
		945	If you encounter strange problems like typing an accented character but
		946	getting two unrelated other characters or similar, or if program output is
		947	subtly garbled, then you should check your locale settings.
		948
		949	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		950	programs running in it. Often rxvt-unicode is started in the C<C> locale,
		951	while the login script running within the rxvt-unicode window changes the
		952	locale to something else, e.g. C<en_GB.UTF-8>. Needless to say, this is
		953	not going to work, and is the most common cause for problems.
		954
		955	The best thing is to fix your startup environment, as you will likely run
		956	into other problems. If nothing works you can try this in your .profile.
		957
		958	printf '\33]701;%s\007' "$LC_CTYPE" # $LANG or $LC_ALL are worth a try, too
		959
		960	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		961	supported on your systems. Some systems have a C<locale> command which
		962	displays this (also, C<perl -e0> can be used to check locale settings, as
		963	it will complain loudly if it cannot set the locale). If it displays something
		964	like:
		965
		966	locale: Cannot set LC_CTYPE to default locale: ...
		967
		968	Then the locale you specified is not supported on your system.
		969
		970	If nothing works and you are sure that everything is set correctly then
		971	you will need to remember a little known fact: Some programs just don't
		972	support locales :(
		973
		974	=head3 How does rxvt-unicode determine the encoding to use?
		975
		976	See next entry.
		977
		978	=head3 Is there an option to switch encodings?
		979
		980	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		981	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		982	UTF-8 or any other encodings with respect to terminal I/O.
		983
		984	The reasons is that there exists a perfectly fine mechanism for selecting
		985	the encoding, doing I/O and (most important) communicating this to all
		986	applications so everybody agrees on character properties such as width
		987	and code number. This mechanism is the I<locale>. Applications not using
		988	that info will have problems (for example, C<xterm> gets the width of
		989	characters wrong as it uses its own, locale-independent table under all
		990	locales).
		991
		992	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		993	programs doing the same (that is, most) will automatically agree in the
		994	interpretation of characters.
		995
		996	Unfortunately, there is no system-independent way to select locales, nor
		997	is there a standard on how locale specifiers will look like.
		998
		999	On most systems, the content of the C<LC_CTYPE> environment variable
		1000	contains an arbitrary string which corresponds to an already-installed
		1001	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		1002	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		1003	(i.e. C<de> or C<german>) are also common.
		1004
		1005	Rxvt-unicode ignores all other locale categories, and except for
		1006	the encoding, ignores country or language-specific settings,
		1007	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		1008	rxvt-unicode.
		1009
		1010	If you want to use a specific encoding you have to make sure you start
		1011	rxvt-unicode with the correct C<LC_CTYPE> category.
		1012
		1013	=head3 Can I switch locales at runtime?
		1014
		1015	Yes, using an escape sequence. Try something like this, which sets
		1016	rxvt-unicode's idea of C<LC_CTYPE>.
		1017
		1018	printf '\33]701;%s\007' ja_JP.SJIS
		1019
		1020	See also the previous answer.
		1021
		1022	Sometimes this capability is rather handy when you want to work in
		1023	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		1024	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		1025	first switches to a locale supported by xjdic and back later:
		1026
		1027	printf '\33]701;%s\007' ja_JP.SJIS
		1028	xjdic -js
		1029	printf '\33]701;%s\007' de_DE.UTF-8
		1030
		1031	You can also use xterm's C<luit> program, which usually works fine, except
		1032	for some locales where character width differs between program- and
		1033	rxvt-unicode-locales.
		1034
		1035	=head3 I have problems getting my input method working.
		1036
		1037	Try a search engine, as this is slightly different for every input method server.
		1038
		1039	Here is a checklist:
		1040
		1041	=over 4
		1042
		1043	=item - Make sure your locale I<and> the imLocale are supported on your OS.
		1044
		1045	Try C<locale -a> or check the documentation for your OS.
		1046
		1047	=item - Make sure your locale or imLocale matches a locale supported by your XIM.
		1048
		1049	For example, B<kinput2> does not support UTF-8 locales, you should use
		1050	C<ja_JP.EUC-JP> or equivalent.
		1051
		1052	=item - Make sure your XIM server is actually running.
		1053
		1054	=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
		1055
		1056	When you want to use e.g. B<kinput2>, it must be set to
		1057	C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
		1058	method servers are running with this command:
		1059
		1060	xprop -root XIM_SERVERS
		1061
		1062	=item
728		1063
729	=back	1064	=back
730		1065
		1066	=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
		1067
		1068	You can specify separate locales for the input method and the rest of the
		1069	terminal, using the resource C<imlocale>:
		1070
		1071	URxvt.imlocale: ja_JP.EUC-JP
		1072
		1073	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		1074	use your input method. Please note, however, that, depending on your Xlib
		1075	version, you may not be able to input characters outside C<EUC-JP> in a
		1076	normal way then, as your input method limits you.
		1077
		1078	=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
		1079
		1080	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		1081	design. Applications can avoid some crashes at the expense of memory
		1082	leaks, and Input Methods can avoid some crashes by careful ordering at
		1083	exit time. B<kinput2> (and derived input methods) generally succeeds,
		1084	while B<SCIM> (or similar input methods) fails. In the end, however,
		1085	crashes cannot be completely avoided even if both sides cooperate.
		1086
		1087	So the only workaround is not to kill your Input Method Servers.
		1088
		1089
		1090	=head2 Operating Systems / Package Maintaining
		1091
		1092	=head3 I am using Debian GNU/Linux and have a problem...
		1093
		1094	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		1095	patches that considerably change the behaviour of rxvt-unicode (but
		1096	unfortunately this notice has been removed). Before reporting a bug to
		1097	the original rxvt-unicode author please download and install the genuine
		1098	version (L<http://software.schmorp.de/pkg/rxvt-unicode.html>) and try to
		1099	reproduce the problem. If you cannot, chances are that the problems are
		1100	specific to Debian GNU/Linux, in which case it should be reported via the
		1101	Debian Bug Tracking System (use C<reportbug> to report the bug).
		1102
		1103	For other problems that also affect the Debian package, you can and
		1104	probably should use the Debian BTS, too, because, after all, it's also a
		1105	bug in the Debian version and it serves as a reminder for other users that
		1106	might encounter the same issue.
		1107
		1108	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		1109
		1110	You should build one binary with the default options. F<configure>
		1111	now enables most useful options, and the trend goes to making them
		1112	runtime-switchable, too, so there is usually no drawback to enabling them,
		1113	except higher disk and possibly memory usage. The perl interpreter should
		1114	be enabled, as important functionality (menus, selection, likely more in
		1115	the future) depends on it.
		1116
		1117	You should not overwrite the C<perl-ext-common> and C<perl-ext> resources
		1118	system-wide (except maybe with C<defaults>). This will result in useful
		1119	behaviour. If your distribution aims at low memory, add an empty
		1120	C<perl-ext-common> resource to the app-defaults file. This will keep the
		1121	perl interpreter disabled until the user enables it.
		1122
		1123	If you can/want build more binaries, I recommend building a minimal
		1124	one with C<--disable-everything> (very useful) and a maximal one with
		1125	C<--enable-everything> (less useful, it will be very big due to a lot of
		1126	encodings built-in that increase download times and are rarely used).
		1127
		1128	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		1129
		1130	It should be, starting with release 7.1. You are encouraged to properly
		1131	install urxvt with privileges necessary for your OS now.
		1132
		1133	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		1134	into a helper process for privileged operations (pty handling on some
		1135	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		1136	immediately. This is much safer than most other terminals that keep
		1137	privileges while running (but is more relevant to urxvt, as it contains
		1138	things as perl interpreters, which might be "helpful" to attackers).
		1139
		1140	This forking is done as the very first within main(), which is very early
		1141	and reduces possible bugs to initialisation code run before main(), or
		1142	things like the dynamic loader of your system, which should result in very
		1143	little risk.
		1144
		1145	=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
		1146
		1147	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
		1148	in your compile environment, or an implementation that implements it,
		1149	whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
		1150	B<wchar_t> is represented as unicode.
		1151
		1152	As you might have guessed, FreeBSD does neither define this symbol nor
		1153	does it support it. Instead, it uses its own internal representation of
		1154	B<wchar_t>. This is, of course, completely fine with respect to standards.
		1155
		1156	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		1157	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>).
		1158
		1159	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		1160	apps in an OS, as using a locale-dependent (and non-standardized)
		1161	representation of B<wchar_t> makes it impossible to convert between
		1162	B<wchar_t> (as used by X11 and your applications) and any other encoding
		1163	without implementing OS-specific-wrappers for each and every locale. There
		1164	simply are no APIs to convert B<wchar_t> into anything except the current
		1165	locale encoding.
		1166
		1167	Some applications (such as the formidable B<mlterm>) work around this
		1168	by carrying their own replacement functions for character set handling
		1169	with them, and either implementing OS-dependent hacks or doing multiple
		1170	conversions (which is slow and unreliable in case the OS implements
		1171	encodings slightly different than the terminal emulator).
		1172
		1173	The rxvt-unicode author insists that the right way to fix this is in the
		1174	system libraries once and for all, instead of forcing every app to carry
		1175	complete replacements for them :)
		1176
		1177	=head3 How can I use rxvt-unicode under cygwin?
		1178
		1179	rxvt-unicode should compile and run out of the box on cygwin, using
		1180	the X11 libraries that come with cygwin. libW11 emulation is no
		1181	longer supported (and makes no sense, either, as it only supported a
		1182	single font). I recommend starting the X-server in C<-multiwindow> or
		1183	C<-rootless> mode instead, which will result in similar look&feel as the
		1184	old libW11 emulation.
		1185
		1186	At the time of this writing, cygwin didn't seem to support any multi-byte
		1187	encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
		1188	to 8-bit encodings.
		1189
		1190	=head3 Character widths are not correct.
		1191
		1192	urxvt uses the system wcwidth function to know the information about
		1193	the width of characters, so on systems with incorrect locale data you
		1194	will likely get bad results. Two notorious examples are Solaris 9,
		1195	where single-width characters like U+2514 are reported as double-width,
		1196	and Darwin 8, where combining chars are reported having width 1.
		1197
		1198	The solution is to upgrade your system or switch to a better one. A
		1199	possibly working workaround is to use a wcwidth implementation like
		1200

		1950	This mode should be enabled I<before> actually enabling mouse reporting,

		1956	ESC [ M c c c 1005, !1015 (three characters)
		1957	ESC [ Pm M 1015 (three or more numeric parameters)
		1958
		1959	The first three parameters are C<code>, C<x> and C<y>. Code is the numeric
		1960	code as for the other modes (but encoded as a decimal number, including
		1961	the additional offset of 32, so you have to subtract 32 first), C<x> and
		1962	C<y> are the coordinates (1|1 is the upper left corner, just as with
		1963	cursor positioning).
		1964
		1965	Example: Shift-Button-1 press at top row, column 80.
		1966
		1967	ESC [ 37 ; 80 ; 1 M
		1968
		1969	One can use this feature by simply enabling it and then looking for
		1970	parameters to the C<ESC [ M> reply - if there are any, this mode is
		1971	active, otherwise one of the old reporting styles is used.
		1972
		1973	Other (to be implemented) reply sequences will use a similar encoding.
		1974
		1975	In the future, more parameters might get added (pixel coordinates for
		1976	example - anybody out there who needs this?).

1539	=head2 Overview of menuBar operation
1540
1541	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1542	of C<Pt> can be used for a variety of tasks:
1543
1544	At the top level is the current menuBar which is a member of a circular
1545	linked-list of other such menuBars.
1546
1547	The menuBar acts as a parent for the various drop-down menus, which in
1548	turn, may have labels, separator lines, menuItems and subMenus.
1549
1550	The menuItems are the useful bits: you can use them to mimic keyboard
1551	input or even to send text or escape sequences back to rxvt.
1552
1553	The menuBar syntax is intended to provide a simple yet robust method of
1554	constructing and manipulating menus and navigating through the
1555	menuBars.
1556
1557	The first step is to use the tag B<< [menu:I<name>] >> which creates
1558	the menuBar called I<name> and allows access. You may now or menus,
1559	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1560	menuBar access as B<readonly> to prevent accidental corruption of the
1561	menus. To re-access the current menuBar for alterations, use the tag
1562	B<[menu]>, make the alterations and then use B<[done]>

1731
1732	To send a string starting with a B<NUL> (B<^@>) character to the
1733	program, start I<action> with a pair of B<NUL> characters (B<^@^@>),
1734	the first of which will be stripped off and the balance directed to the
1735	program. Otherwise if I<action> begins with B<NUL> followed by
1736	non-+B<NUL> characters, the leading B<NUL> is stripped off and the
1737	balance is sent back to rxvt.
1738
1739	As a convenience for the many Emacs-type editors, I<action> may start
1740	with B<M-> (eg, B<M-$> is equivalent to B<\E$>) and a B<CR> will be
1741	appended if missed from B<M-x> commands.
1742
1743	As a convenience for issuing XTerm B<ESC ]> sequences from a menubar (or
1744	quick arrow), a B<BEL> (B<^G>) will be appended if needed.

1770	The left label I<is> necessary, since it's used for matching, but
1771	implicitly hiding the left label (by using same name for both left and
