		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.

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

		101	@@URXVT_NAME@@d -q -o -f

		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, an 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 libAfterImage or 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).

		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:

		530	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?

		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.

		580	=head3 Mouse cut/paste suddenly no longer works.

		777
		778	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		779	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		780	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		781	font (different glyphs for C<;> and many other harmless characters),
		782	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		783	bold version has less chars than the medium version, so I use it for rare
		784	characters, too. When editing sources with vim, I use italic for comments
		785	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		786
		787	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		788	purposes, it works, and gives a different look, as my normal (Non-bold)
		789	font is already bold, and I want to see a difference between bold and
		790	normal fonts.
		791
		792	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		793	class name. That is because I use different configs for different purposes,
		794	for example, my IRC window is started with C<-name IRC>, and uses these
		795	defaults:
		796
		797	IRC*title: IRC
		798	IRC*geometry: 87x12+535+542
		799	IRC*saveLines: 0
		800	IRC*mapAlert: true
		801	IRC*font: suxuseuro

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

		1200
		1201	urxvt uses the system wcwidth function to know the information about
		1202	the width of characters, so on systems with incorrect locale data you
		1203	will likely get bad results. Two notorious examples are Solaris 9,
		1204	where single-width characters like U+2514 are reported as double-width,
		1205	and Darwin 8, where combining chars are reported having width 1.
		1206
		1207	The solution is to upgrade your system or switch to a better one. A
		1208	possibly working workaround is to use a wcwidth implementation like

		1958
		1959	This mode should be enabled I<before> actually enabling mouse reporting,
		1960	for semi-obvious reasons.
		1961
		1962	The sequences received for various modes are as follows:
		1963
		1964	ESC [ M o o o !1005, !1015 (three octets)
		1965	ESC [ M c c c 1005, !1015 (three characters)
		1966	ESC [ Pm M 1015 (three or more numeric paramaters)
		1967
		1968	The three parameters are C<code>, C<x> and C<y>. Code is the numeric code
		1969	as for the other modes (but encoded as a decimal number), C<x> and C<y>
		1970	are the coordinates (1\|1 is the upper left corner, just as with cursor
		1971	positioning).
		1972
		1973	Example: Shift-Button-1 press at top row, column 80.
		1974
		1975	ESC [ 5 ; 80 ; 1 M
		1976
		1977	One can use this feature by simply enabling it and then looking for
		1978	parameters to the C<ESC [ M> reply - if there are any, this mode is
		1979	active, otherwise one of the old reporting styles is used.
		1980
		1981	Other (to be implemented) reply sequences will use a similar encoding.
		1982
		1983	In the future, more parameters might get added (pixel coordinates for
		1984	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.

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
