		29	=head3 My question isn't answered here, can I ask a human?
		30
		31	Before sending me mail, you could go to IRC: C<irc.freenode.net>,
		32	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
		33	interested in learning about new and exciting problems (but not FAQs :).
		34
		35	=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
		36
		37	Beginning with version 7.3, there is a perl extension that implements a
		38	simple tabbed terminal. It is installed by default, so any of these should
		39	give you tabs:
		40
		41	@@URXVT_NAME@@ -pe tabbed
		42
		43	URxvt.perl-ext-common: default,tabbed
		44
		45	It will also work fine with tabbing functionality of many window managers
		46	or similar tabbing programs, and its embedding-features allow it to be
		47	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
		48	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
		49	(murxvt) terminal as an example embedding application.

14	=item When I log-in to another system it tells me about missing terminfo data?
15
16	The terminal description used by rxvt-unicode is not as widely available
17	as that for xterm, or even rxvt (for which the same problem often arises).
18
19	The correct solution for this problem is to install the terminfo, this can
20	be done like this (with ncurses' infocmp):
21
22	REMOTE=remotesystem.domain
23	infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
24
25	... or by installing rxvt-unicode normally on the remote system,
26
27	If you cannot or do not want to do this, then you can simply set
28	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
29	problems arising, which includes wrong keymapping, less and different
30	colours and some refresh errors in fullscreen applications. It's a nice
31	quick-and-dirty workaround for rare cases, though.
32
33	If you always want to do this you can either recompile rxvt-unicode with
34	the desired TERM value or use a resource to set it:
35
36	URxvt.termName: rxvt
37
38	If you don't plan to use B<rxvt> (quite common...) you could also replace
39	the rxvt terminfo file with the rxvt-unicode one.
40
41	=item I need a termcap file entry.
42
43	You could use rxvt's termcap entry with resonable results in many cases.
44	You can also create a termcap entry by using terminfo's infocmp program
45	like this:
46
47	infocmp -C rxvt-unicode
48
49	OR you could this termcap entry:

71	=item How can I configure rxvt-unicode so that it looks similar to the original rxvt?
72
73	Felix von Leitner says that these two lines, in your F<.Xdefaults>, will make rxvt-unicode
74	behave similar to the original rxvt:
75
76	URxvt.font: -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso8859-1
77	URxvt.boldFont: -misc-fixed-bold-r-semicondensed--13-120-75-75-c-60-iso8859-1
78
79	=item Rxvt-unicode does not seem to understand the selected encoding?
80
81	=item Unicode does not seem to work?
82
83	If you encounter strange problems like typing an accented character but
84	getting two unrelated other characters or similar, or if program output is
85	subtly garbled, then you should check your locale settings.
86
87	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
88	programs. Often rxvt-unicode is started in the C<C> locale, while the
89	login script running within the rxvt-unicode window changes the locale to
90	sth. else, e.h. C<en_GB.UTF-8>. Needless to say, this is not going to work.
91
92	The best thing is to fix your startup environment, as you will likely run
93	into other problems. If nothing works you can try this in your .profile.
94
95	printf '\e]701;%s\007' "$LC_CTYPE"
96
97	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
98	supported on your systems. Some systems have a C<locale> command which
99	displays this. If it displays sth. like:
100
101	locale: Cannot set LC_CTYPE to default locale: ...
102
103	Then the locale you specified is not supported on your system.
104
105	If nothing works and you are sure that everything is set correctly then
106	you will need to remember a little known fact: Some programs just don't
107	support locales :(
108
109	=item Why do some characters look so much different than others?
110
111	=item How does rxvt-unicode choose fonts?
112
113	Most fonts do not contain the full range of Unicode, which is
114	fine. Chances are that the font you (or the admin/package maintainer of
115	your system/os) have specified does not cover all the characters you want
116	to display.
117
118	B<rxvt-unicode> makes a best-effort try at finding a replacement
119	font. Often the result is fine, but sometimes the chosen font looks
120	bad. Many fonts have totally strange characters that don't resemble the
121	correct glyph at all, and rxvt-unicode lacks the artificial intelligence
122	to detect that a specific glyph is wrong: it has to believe the font that
123	the characters it contains indeed look correct.
124
125	In that case, select a font of your taste and add it to the font list,
126	e.g.:
127
128	@@RXVT_NAME@@ -fn basefont,font2,font3...
129
130	When rxvt-unicode sees a character, it will first look at the base
131	font. If the base font does not contain the character, it will go to the
132	next font, and so on. Specifying your own fonts will also speed up this
133	search and use less resources within rxvt-unicode and the X-server.
134
135	The only limitation is that all the fonts must not be larger than the base
136	font, as the base font defines the principal cell size, which must be the
137	same due to the way terminals work.
138
139	=item Why do some chinese characters look so different than others?
140
141	This is because there is a difference between script and language --
142	rxvt-unicode does not know which language the text that is output
143	is, as it only knows the unicode character codes. If rxvt-unicode
144	first sees a japanese character, it might choose a japanese font for
145	it. Subsequent japanese characters will take that font. Now, many chinese
146	characters aren't represented in japanese fonts, so when the first
147	non-japanese character comes up, rxvt-unicode will look for a chinese font
148	-- unfortunately at this point, it will still use the japanese font for
149	japanese characters that are also chinese.
150
151	The workaround is easy: just tag a chinese font at the end of your font
152	list (see the previous question). The key is to view the font list as
153	a preference list: If you expect more japanese, list a japanese font
154	first. If you expect more chinese, put a chinese font first.
155
156	In the future it might be possible to switch preferences at runtime (the
157	internal data structure has no problem with using different fonts for
158	the same character at the same time, but no interface for this has been
159	designed yet).
160
161	=item Why does rxvt-unicode sometimes leave pixel droppings?
162
163	Most fonts were not designed for terminal use, which means that character
164	size varies a lot. A font that is otherwise fine for terminal use might
165	contain some characters that are simply too wide. Rxvt-unicode will avoid
166	these characters. For characters that are just "a bit" too wide a special
167	"careful" rendering mode is used that redraws adjacent characters.
168
169	All of this requires that fonts do not lie about character sizes,
170	however: Xft fonts often draw glyphs larger than their acclaimed bounding
171	box, and rxvt-unicode has no way of detecting this (the correct way is to
172	ask for the character bounding box, which unfortunately is wrong in these
173	cases).
174
175	It's not clear (to me at least), wether this is a bug in Xft, freetype, or
176	the respective font. If you encounter this problem there is no way to work
177	around this except by using a different font.
178
179	All of this is not a problem when using X11 core fonts, as their bounding
180	box data is correct.
181
182	=item My Compose (Multi_key) key is no longer working.
183
184	The most common causes for this are that either your locale is not set
185	correctly, or you specified a B<preeditStyle> that is not supported by
186	your input method. For example, if you specified B<OverTheSpot> and
187	your input method (e.g. the default input method handling Compose keys)
188	does not support this (for instance because it is not visual), then
189	rxvt-unicode will continue without an input method.
190
191	In this case either do not specify a B<preeditStyle> or specify more than
192	one pre-edit style, such as B<OverTheSpot,Root,None>.
193
194	=item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
195
196	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
197	international keyboards) or simply use ISO 14755 support to your
198	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
199	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
200	character and so on.
201
202	=item How can I keep rxvt-unicode from using reverse video so much?
203
204	First of all, make sure you are running with the right terminfo
205	(C<urxvt>), which will get rid of most of these effects. Then make sure
206	you have specified colours for italic and bold, as otherwise rxvt-unicode
207	might use reverse video to simulate the effect:
208
209	URxvt*colorBD: white
210	URxvt*colorIT: green
211
212	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
213
214	For some unexplainable reason, some programs (i.e. irssi) assume a very
215	weird colour palette when confronted with a terminal with more than the
216	standard 8 colours (rxvt-unicode supports 88). The right fix is, of
217	course, to fix these programs not to assume non-ISO colours without very
218	good reasons.
219
220	In the meantime, you can either edit your C<urxvt> terminfo definition to
221	only claim 8 colour support or use C<TERM=rxvt>, which will fix colours
222	but keep you from using other rxvt-unicode features.
223
224	=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
225
226	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
227	in your compile environment, or an implementation that implements it,
228	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
229	B<wchar_t> is represented as unicode.
230
231	As you might have guessed, FreeBSD does neither define this symobl nor
232	does it support it. Instead, it uses it's own internal representation of
233	B<wchar_t>. This is, of course, completely legal.
234
235	However, C<__STDC_ISO_10646__> is the only sane way to support
236	multi-language apps in an OS, as using a locale-dependent (and
237	non-standardized) representation of B<wchar_t> makes it impossible to
238	convert between B<wchar_t> (as used by X11 and your applications) and any
239	other encoding without implementing OS-specific-wrappers for each and
240	every locale. There simply are no APIs to convert B<wchar_t> into anything
241	except the current locale encoding.
242
243	Some applications (such as the formidable B<mlterm>) work around this
244	by carrying their own replacement functions for character set handling
245	with them, and either implementing OS-dependent hacks or doing multiple
246	conversions (which is slow and unreliable in case the OS implements
247	encodings slightly different than the terminal emulator).
248
249	The rxvt-unicode author insists that the right way to fix this is in the
250	system libraries once and for all, instead of forcing every app to carry
251	complete replacements.
252
253	=item How does rxvt-unicode determine the encoding to use?
254
255	=item Is there an option to switch encodings?
256
257	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
258	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
259	UTF-8 or any other encodings with respect to terminal I/O.
260
261	The reasons is that there exists a perfectly fine mechanism for selecting
262	the encoding, doing I/O and (most important) communicating this to all
263	applications so everybody agrees on character properties such as width and
264	code number. This mechanism is the I<locale>.
265
266	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
267	programs doing the same (that is, most) will automatically agree in the
268	interpretation of characters.
269
270	Unfortunately, there is no system-independent way to select locales, nor
271	is there a standard on how locale specifiers will look like.
272
273	On most systems, the content of the C<LC_CTYPE> environment variable
274	contains an arbitrary string which corresponds to an already-installed
275	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
276	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
277	(i.e. C<de> or C<german>) are also common.
278
279	Rxvt-unicode ignores all other locale categories, and except for
280	the encoding, ignores country or language-specific settings,
281	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the same for rxvt-unicode.
282
283	If you want to use a specific encoding you have to make sure you start
284	rxvt-unicode with the correct C<LC_CTYPE> category.
285
286	=item Can I switch locales at runtime?
287
288	Yes, using an escape sequence. Try sth. like this, which sets
289	rxvt-unicode's idea of C<LC_CTYPE>.
290
291	printf '\e]701;%s\007' ja_JP.SJIS
292
293	See also the previous question.
294
295	Sometimes this capability is rather handy when you want to work in one
296	locale (e.g. C<de_DE.UTF-8>) but some programs don't support UTF-8. For
297	example, I use this script to start C<xjdic>, which first switches to a
298	locale supported by xjdic and back later:
299
300	printf '\e]701;%s\007' ja_JP.SJIS
301	xjdic -js
302	printf '\e]701;%s\007' de_DE.UTF-8
303
304	=item Can I switch the fonts at runtime?
305
306	Yes, using an escape sequence. Try sth. like this, which has the same
307	effect as using the C<-fn> switch, and takes effect immediately:
308
309	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
310
311	This is useful if you e.g. work primarily with japanese (and prefer a
312	japanese font), but you have to switch to chinese temporarily, where
313	japanese fonts would only be in your way.
314
315	You can think of this as a kind of manual ISO-2022 switching.
316
317	=item Why do italic characters look as if clipped?
318
319	Many fonts have difficulties with italic characters and hinting. For
320	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
321	Mono> completely fails in it's italic face. A workaround is to enable
322	freetype autohinting, i.e. like this:
323
324	URxvt*italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
325	URxvt*boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
326
327	=item My input method wants <some encoding> but I want UTF-8, what can I do?
328
329	You can specify separate locales for the input method and the rest of the
330	terminal, using the resource C<imlocale>:
331
332	URxvt*imlocale: ja_JP.EUC-JP
333
334	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
335	use your input method. Please note, however, that you will not be able to
336	input characters outside C<EUC-JP> in a normal way then, as your input
337	method limits you.

		73	=head3 How can I start @@URXVT_NAME@@d in a race-free way?
		74
		75	Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
		76	display, create the listening socket and then fork.
		77
		78	=head3 How can I start @@URXVT_NAME@@d automatically when I run URXVT_NAME@@c?
		79
		80	If you want to start @@URXVT_NAME@@d automatically whenever you run
		81	@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
		82
		83	#!/bin/sh
		84	@@URXVT_NAME@@c "$@"
		85	if [ $? -eq 2 ]; then
		86	@@URXVT_NAME@@d -q -o -f
		87	@@URXVT_NAME@@c "$@"
		88	fi
		89
		90	This tries to create a new terminal, and if fails with exit status 2,
		91	meaning it couldn't connect to the daemon, it will start the daemon and
		92	re-run the command. Subsequent invocations of the script will re-use the
		93	existing daemon.
		94
		95	=head3 How do I distinguish wether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
		96
		97	The original rxvt and rxvt-unicode always export the variable "COLORTERM",
		98	so you can check and see if that is set. Note that several programs, JED,
		99	slrn, Midnight Commander automatically check this variable to decide
		100	whether or not to use color.

		102	=head3 How do I set the correct, full IP address for the DISPLAY variable?
		103
		104	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		105	insecure mode then it is possible to use the following shell script
		106	snippets to correctly set the display. If your version of rxvt-unicode
		107	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		108	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		109	regular xterm.

		126
		127	=head3 How do I compile the manual pages on my own?
		128
		129	You need to have a recent version of perl installed as F</usr/bin/perl>,
		130	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
		131	the doc subdirectory and enter C<make alldoc>.
		132
		133	=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
		134
		135	I often get asked about this, and I think, no, they didn't cause extra
		136	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		137	that the urxvt binary is larger (due to some encoding tables always being
		138	compiled in), but it actually uses less memory (RSS) after startup. Even
		139	with C<--disable-everything>, this comparison is a bit unfair, as many
		140	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		141	already in use in this mode.
		142
		143	text data bss drs rss filename
		144	98398 1664 24 15695 1824 rxvt --disable-everything
		145	188985 9048 66616 18222 1788 urxvt --disable-everything
		146
		147	When you C<--enable-everything> (which I<is> unfair, as this involves xft
		148	and full locale/XIM support which are quite bloaty inside libX11 and my
		149	libc), the two diverge, but not unreasnobaly so.
		150
		151	text data bss drs rss filename
		152	163431 2152 24 20123 2060 rxvt --enable-everything
		153	1035683 49680 66648 29096 3680 urxvt --enable-everything
		154
		155	The very large size of the text section is explained by the east-asian
		156	encoding tables, which, if unused, take up disk space but nothing else
		157	and can be compiled out unless you rely on X11 core fonts that use those
		158	encodings. The BSS size comes from the 64k emergency buffer that my c++
		159	compiler allocates (but of course doesn't use unless you are out of
		160	memory). Also, using an xft font instead of a core font immediately adds a
		161	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		162	not used.
		163
		164	Of course, due to every character using two or four bytes instead of one,
		165	a large scrollback buffer will ultimately make rxvt-unicode use more
		166	memory.
		167
		168	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		169	still fares rather well. And compared to some monsters like gnome-terminal
		170	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		171	43180k in daemons that stay around after exit, plus half a minute of
		172	startup time, including the hundreds of warnings it spits out), it fares
		173	extremely well *g*.
		174
		175	=head3 Why C++, isn't that unportable/bloated/uncool?
		176
		177	Is this a question? :) It comes up very often. The simple answer is: I had
		178	to write it, and C++ allowed me to write and maintain it in a fraction
		179	of the time and effort (which is a scarce resource for me). Put even
		180	shorter: It simply wouldn't exist without C++.
		181
		182	My personal stance on this is that C++ is less portable than C, but in
		183	the case of rxvt-unicode this hardly matters, as its portability limits
		184	are defined by things like X11, pseudo terminals, locale support and unix
		185	domain sockets, which are all less portable than C++ itself.
		186
		187	Regarding the bloat, see the above question: It's easy to write programs
		188	in C that use gobs of memory, an certainly possible to write programs in
		189	C++ that don't. C++ also often comes with large libraries, but this is
		190	not necessarily the case with GCC. Here is what rxvt links against on my
		191	system with a minimal config:
		192
		193	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		194	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		195	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		196	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		197
		198	And here is rxvt-unicode:
		199
		200	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		201	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		202	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		203	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		204	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		205
		206	No large bloated libraries (of course, none were linked in statically),
		207	except maybe libX11 :)

		209
		210	=head2 Rendering, Font & Look and Feel Issues
		211
		212	=head3 I can't get transparency working, what am I doing wrong?
		213
		214	First of all, transparency isn't officially supported in rxvt-unicode, so
		215	you are mostly on your own. Do not bug the author about it (but you may
		216	bug everybody else). Also, if you can't get it working consider it a rite
		217	of passage: ... and you failed.
		218
		219	Here are four ways to get transparency. B<Do> read the manpage and option
		220	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		221
		222	1. Use inheritPixmap:
		223
		224	Esetroot wallpaper.jpg
		225	@@URXVT_NAME@@ -ip -tint red -sh 40
		226
		227	That works. If you think it doesn't, you lack transparency and tinting
		228	support, or you are unable to read.
		229
		230	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		231	to use effects other than tinting and shading: Just shade/tint/whatever
		232	your picture with gimp or any other tool:
		233
		234	convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
		235	@@URXVT_NAME@@ -pixmap background.xpm -pe automove-background
		236
		237	That works. If you think it doesn't, you lack XPM and Perl support, or you
		238	are unable to read.
		239
		240	3. Use an ARGB visual:
		241
		242	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		243
		244	This requires XFT support, and the support of your X-server. If that
		245	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		246	there yet, no matter what they claim. Rxvt-Unicode contains the neccessary
		247	bugfixes and workarounds for Xft and Xlib to make it work, but that
		248	doesn't mean that your WM has the required kludges in place.
		249
		250	4. Use xcompmgr and let it do the job:
		251
		252	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		253	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		254
		255	Then click on a window you want to make transparent. Replace C<0xc0000000>
		256	by other values to change the degree of opacity. If it doesn't work and
		257	your server crashes, you got to keep the pieces.
		258
		259	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		260
		261	Most fonts were not designed for terminal use, which means that character
		262	size varies a lot. A font that is otherwise fine for terminal use might
		263	contain some characters that are simply too wide. Rxvt-unicode will avoid
		264	these characters. For characters that are just "a bit" too wide a special
		265	"careful" rendering mode is used that redraws adjacent characters.
		266
		267	All of this requires that fonts do not lie about character sizes,
		268	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		269	box, and rxvt-unicode has no way of detecting this (the correct way is to
		270	ask for the character bounding box, which unfortunately is wrong in these
		271	cases).
		272
		273	It's not clear (to me at least), wether this is a bug in Xft, freetype,
		274	or the respective font. If you encounter this problem you might try using
		275	the C<-lsp> option to give the font more height. If that doesn't work, you
		276	might be forced to use a different font.
		277
		278	All of this is not a problem when using X11 core fonts, as their bounding
		279	box data is correct.
		280
		281	=head3 How can I keep rxvt-unicode from using reverse video so much?
		282
		283	First of all, make sure you are running with the right terminal settings
		284	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		285	make sure you have specified colours for italic and bold, as otherwise
		286	rxvt-unicode might use reverse video to simulate the effect:
		287
		288	URxvt.colorBD: white
		289	URxvt.colorIT: green
		290
		291	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		292
		293	For some unexplainable reason, some rare programs assume a very weird
		294	colour palette when confronted with a terminal with more than the standard
		295	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		296	these programs not to assume non-ISO colours without very good reasons.
		297
		298	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		299	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		300	fix colours but keep you from using other rxvt-unicode features.
		301
		302	=head3 Can I switch the fonts at runtime?
		303
		304	Yes, using an escape sequence. Try something like this, which has the same
		305	effect as using the C<-fn> switch, and takes effect immediately:
		306
		307	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
		308
		309	This is useful if you e.g. work primarily with japanese (and prefer a
		310	japanese font), but you have to switch to chinese temporarily, where
		311	japanese fonts would only be in your way.
		312
		313	You can think of this as a kind of manual ISO-2022 switching.
		314
		315	=head3 Why do italic characters look as if clipped?
		316
		317	Many fonts have difficulties with italic characters and hinting. For
		318	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		319	Mono> completely fails in it's italic face. A workaround might be to
		320	enable freetype autohinting, i.e. like this:
		321
		322	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		323	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true

		407
		408	=head3 Why do some characters look so much different than others?
		409
		410	See next entry.
		411
		412	=head3 How does rxvt-unicode choose fonts?
		413
		414	Most fonts do not contain the full range of Unicode, which is
		415	fine. Chances are that the font you (or the admin/package maintainer of
		416	your system/os) have specified does not cover all the characters you want
		417	to display.
		418
		419	B<rxvt-unicode> makes a best-effort try at finding a replacement
		420	font. Often the result is fine, but sometimes the chosen font looks
		421	bad/ugly/wrong. Some fonts have totally strange characters that don't
		422	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		423	intelligence to detect that a specific glyph is wrong: it has to believe
		424	the font that the characters it claims to contain indeed look correct.
		425
		426	In that case, select a font of your taste and add it to the font list,
		427	e.g.:
		428
		429	@@URXVT_NAME@@ -fn basefont,font2,font3...
		430
		431	When rxvt-unicode sees a character, it will first look at the base
		432	font. If the base font does not contain the character, it will go to the
		433	next font, and so on. Specifying your own fonts will also speed up this
		434	search and use less resources within rxvt-unicode and the X-server.
		435
		436	The only limitation is that none of the fonts may be larger than the base
		437	font, as the base font defines the terminal character cell size, which
		438	must be the same due to the way terminals work.
		439
		440	=head3 Why do some chinese characters look so different than others?
		441
		442	This is because there is a difference between script and language --
		443	rxvt-unicode does not know which language the text that is output is,
		444	as it only knows the unicode character codes. If rxvt-unicode first
		445	sees a japanese/chinese character, it might choose a japanese font for
		446	display. Subsequent japanese characters will use that font. Now, many
		447	chinese characters aren't represented in japanese fonts, so when the first
		448	non-japanese character comes up, rxvt-unicode will look for a chinese font
		449	-- unfortunately at this point, it will still use the japanese font for
		450	chinese characters that are also in the japanese font.
		451
		452	The workaround is easy: just tag a chinese font at the end of your font
		453	list (see the previous question). The key is to view the font list as
		454	a preference list: If you expect more japanese, list a japanese font
		455	first. If you expect more chinese, put a chinese font first.
		456
		457	In the future it might be possible to switch language preferences at
		458	runtime (the internal data structure has no problem with using different
		459	fonts for the same character at the same time, but no interface for this
		460	has been designed yet).
		461
		462	Until then, you might get away with switching fonts at runtime (see L<Can
		463	I switch the fonts at runtime?> later in this document).

		465	=head2 Keyboard, Mouse & User Interaction
		466
		467	=head3 The new selection selects pieces that are too big, how can I select single words?
		468
		469	If you want to select e.g. alphanumeric words, you can use the following
		470	setting:
		471
		472	URxvt.selection.pattern-0: ([[:word:]]+)
		473
		474	If you click more than twice, the selection will be extended
		475	more and more.
		476
		477	To get a selection that is very similar to the old code, try this pattern:
		478
		479	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		480
		481	Please also note that the I<LeftClick Shift-LeftClik> combination also

		483
		484	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?

		486	You can disable the perl extension completely by setting the

		488	rxvt-unicode from initialising perl, saving memory.
		489
		490	If you only want to disable specific features, you first have to
		491	identify which perl extension is responsible. For this, read the section
		492	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		493	example, to disable the B<selection-popup> and B<option-popup>, specify
		494	this B<perl-ext-common> resource:
		495
		496	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		497
		498	This will keep the default extensions, but disable the two popup
		499	extensions. Some extensions can also be configured, for example,
		500	scrollback search mode is triggered by B<M-s>. You can move it to any
		501	other combination either by setting the B<searchable-scrollback> resource:
		502

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

		508
		509	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		510
		511	These are caused by the C<readline> perl extension. Under normal
		512	circumstances, it will move your cursor around when you click into the
		513	line that contains it. It tries hard not to do this at the wrong moment,
		514	but when running a program that doesn't parse cursor movements or in some
		515	cases during rlogin sessions, it fails to detect this properly.
		516
		517	You can permamently switch this feature off by disabling the C<readline>
		518	extension:
		519
		520	URxvt.perl-ext-common: default,-readline
		521
		522	=head3 My numerical keypad acts weird and generates differing output?
		523
		524	Some Debian GNUL/Linux users seem to have this problem, although no
		525	specific details were reported so far. It is possible that this is caused
		526	by the wrong C<TERM> setting, although the details of wether and how
		527	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		528	keymap. See the answer to the previous question, and please report if that
		529	helped.
		530
		531	=head3 My Compose (Multi_key) key is no longer working.
		532
		533	The most common causes for this are that either your locale is not set
		534	correctly, or you specified a B<preeditStyle> that is not supported by
		535	your input method. For example, if you specified B<OverTheSpot> and
		536	your input method (e.g. the default input method handling Compose keys)
		537	does not support this (for instance because it is not visual), then
		538	rxvt-unicode will continue without an input method.
		539
		540	In this case either do not specify a B<preeditStyle> or specify more than
		541	one pre-edit style, such as B<OverTheSpot,Root,None>.
		542
		543	=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		544
		545	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		546	international keyboards) or simply use ISO 14755 support to your
		547	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		548	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		549	character and so on.
		550
		551	=head3 Mouse cut/paste suddenly no longer works.
		552
		553	Make sure that mouse reporting is actually turned off since killing
		554	some editors prematurely may leave the mouse in mouse report mode. I've
		555	heard that tcsh may use mouse reporting unless it otherwise specified. A
		556	quick check is to see if cut/paste works when the Alt or Shift keys are
		557	depressed.

		686	as that for xterm, or even rxvt (for which the same problem often arises).
		687
		688	The correct solution for this problem is to install the terminfo, this can
		689	be done like this (with ncurses' infocmp):
		690
		691	REMOTE=remotesystem.domain
		692	infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
		693
		694	... or by installing rxvt-unicode normally on the remote system,
		695
		696	If you cannot or do not want to do this, then you can simply set
		697	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		698	problems arising, which includes wrong keymapping, less and different
		699	colours and some refresh errors in fullscreen applications. It's a nice
		700	quick-and-dirty workaround for rare cases, though.
		701
		702	If you always want to do this (and are fine with the consequences) you
		703	can either recompile rxvt-unicode with the desired TERM value or use a
		704	resource to set it:
		705
		706	URxvt.termName: rxvt
		707
		708	If you don't plan to use B<rxvt> (quite common...) you could also replace
		709	the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
		710
		711	=head3 C<tic> outputs some error when compiling the terminfo entry.
		712
		713	Most likely it's the empty definition for C<enacs=>. Just replace it by

		720	=head3 I need a termcap file entry.
		721
		722	One reason you might want this is that some distributions or operating

		724	library (Fedora Core's bash is one example) and rely on a termcap entry
		725	for C<rxvt-unicode>.
		726
		727	You could use rxvt's termcap entry with resonable results in many cases.
		728	You can also create a termcap entry by using terminfo's infocmp program
		729	like this:
		730
		731	infocmp -C rxvt-unicode
		732
		733	Or you could use this termcap entry, generated by the command above:

		778
		779	=head3 Why are the secondary screen-related options not working properly?
		780
		781	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		782	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		783	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		784	features. Unfortunately, some of these (most notably, again, Debian
		785	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		786	file, so you will need to install it on your own (See the question B<When
		787	I log-in to another system it tells me about missing terminfo data?> on
		788	how to do this).

		798
		799	If you encounter strange problems like typing an accented character but
		800	getting two unrelated other characters or similar, or if program output is
		801	subtly garbled, then you should check your locale settings.
		802
		803	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		804	programs. Often rxvt-unicode is started in the C<C> locale, while the
		805	login script running within the rxvt-unicode window changes the locale to
		806	something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
		807
		808	The best thing is to fix your startup environment, as you will likely run
		809	into other problems. If nothing works you can try this in your .profile.

		811	printf '\e]701;%s\007' "$LC_CTYPE"
		812
		813	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		814	supported on your systems. Some systems have a C<locale> command which
		815	displays this (also, C<perl -e0> can be used to check locale settings, as
		816	it will complain loudly if it cannot set the locale). If it displays something
		817	like:
		818
		819	locale: Cannot set LC_CTYPE to default locale: ...
		820
		821	Then the locale you specified is not supported on your system.
		822
		823	If nothing works and you are sure that everything is set correctly then
		824	you will need to remember a little known fact: Some programs just don't
		825	support locales :(
		826
		827	=head3 How does rxvt-unicode determine the encoding to use?
		828
		829	See next entry.
		830
		831	=head3 Is there an option to switch encodings?
		832
		833	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		834	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		835	UTF-8 or any other encodings with respect to terminal I/O.
		836
		837	The reasons is that there exists a perfectly fine mechanism for selecting
		838	the encoding, doing I/O and (most important) communicating this to all
		839	applications so everybody agrees on character properties such as width
		840	and code number. This mechanism is the I<locale>. Applications not using
		841	that info will have problems (for example, C<xterm> gets the width of
		842	characters wrong as it uses it's own, locale-independent table under all
		843	locales).
		844
		845	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		846	programs doing the same (that is, most) will automatically agree in the
		847	interpretation of characters.
		848
		849	Unfortunately, there is no system-independent way to select locales, nor
		850	is there a standard on how locale specifiers will look like.
		851
		852	On most systems, the content of the C<LC_CTYPE> environment variable
		853	contains an arbitrary string which corresponds to an already-installed
		854	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		855	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		856	(i.e. C<de> or C<german>) are also common.
		857
		858	Rxvt-unicode ignores all other locale categories, and except for
		859	the encoding, ignores country or language-specific settings,
		860	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		861	rxvt-unicode.
		862
		863	If you want to use a specific encoding you have to make sure you start
		864	rxvt-unicode with the correct C<LC_CTYPE> category.
		865
		866	=head3 Can I switch locales at runtime?
		867
		868	Yes, using an escape sequence. Try something like this, which sets
		869	rxvt-unicode's idea of C<LC_CTYPE>.
		870
		871	printf '\e]701;%s\007' ja_JP.SJIS
		872
		873	See also the previous answer.
		874
		875	Sometimes this capability is rather handy when you want to work in
		876	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		877	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		878	first switches to a locale supported by xjdic and back later:
		879
		880	printf '\e]701;%s\007' ja_JP.SJIS
		881	xjdic -js
		882	printf '\e]701;%s\007' de_DE.UTF-8
		883
		884	You can also use xterm's C<luit> program, which usually works fine, except
		885	for some locales where character width differs between program- and
		886	rxvt-unicode-locales.
		887
		888	=head3 I have problems getting my input method working.
		889
		890	Try a search engine, as this is slightly different for every input method server.
		891
		892	Here is a checklist:
		893
		894	=over 4
		895
		896	=item - Make sure your locale I<and> the imLocale are supported on your OS.
		897
		898	Try C<locale -a> or check the documentation for your OS.
		899
		900	=item - Make sure your locale or imLocale matches a locale supported by your XIM.
		901
		902	For example, B<kinput2> does not support UTF-8 locales, you should use
		903	C<ja_JP.EUC-JP> or equivalent.
		904
		905	=item - Make sure your XIM server is actually running.
		906
		907	=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
		908
		909	When you want to use e.g. B<kinput2>, it must be set to
		910	C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. Youc an see what input
		911	method servers are running with this command:
		912
		913	xprop -root XIM_SERVERS
		914

610	=head1 SYNOPSIS	919	=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
611		920
612	# set a new font set	921	You can specify separate locales for the input method and the rest of the
613	printf '\33]50;%s\007' 9x15,xft:Kochi" Mincho"	922	terminal, using the resource C<imlocale>:
614		923
615	# change the locale and tell rxvt-unicode about it	924	URxvt.imlocale: ja_JP.EUC-JP
616	export LC_CTYPE=ja_JP.EUC-JP; printf "\33]701;$LC_CTYPE\007"
617		925
618	# set window title	926	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
619	printf '\33]2;%s\007' "new window title"	927	use your input method. Please note, however, that, depending on your Xlib
		928	version, you may not be able to input characters outside C<EUC-JP> in a
		929	normal way then, as your input method limits you.
620		930
621	=head1 DESCRIPTION	931	=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
		932
		933	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		934	design. Applications can avoid some crashes at the expense of memory
		935	leaks, and Input Methods can avoid some crashes by careful ordering at
		936	exit time. B<kinput2> (and derived input methods) generally succeeds,
		937	while B<SCIM> (or similar input methods) fails. In the end, however,
		938	crashes cannot be completely avoided even if both sides cooperate.
		939
		940	So the only workaround is not to kill your Input Method Servers.
		941
		942
		943	=head2 Operating Systems / Package Maintaining
		944
		945	=head3 I am using Debian GNU/Linux and have a problem...
		946
		947	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		948	patches that considerably change the behaviour of rxvt-unicode (but
		949	unfortunately this notice has been removed). Before reporting a bug to
		950	the original rxvt-unicode author please download and install the genuine
		951	version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
		952	the problem. If you cannot, chances are that the problems are specific to
		953	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		954	Tracking System (use C<reportbug> to report the bug).
		955
		956	For other problems that also affect the Debian package, you can and
		957	probably should use the Debian BTS, too, because, after all, it's also a
		958	bug in the Debian version and it serves as a reminder for other users that
		959	might encounter the same issue.
		960
		961	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		962
		963	You should build one binary with the default options. F<configure>
		964	now enables most useful options, and the trend goes to making them
		965	runtime-switchable, too, so there is usually no drawback to enbaling them,
		966	except higher disk and possibly memory usage. The perl interpreter should
		967	be enabled, as important functionality (menus, selection, likely more in
		968	the future) depends on it.
		969
		970	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		971	system-wide (except maybe with C<defaults>). This will result in useful
		972	behaviour. If your distribution aims at low memory, add an empty
		973	C<perl-ext-common> resource to the app-defaults file. This will keep the
		974	perl interpreter disabled until the user enables it.
		975
		976	If you can/want build more binaries, I recommend building a minimal
		977	one with C<--disable-everything> (very useful) and a maximal one with
		978	C<--enable-everything> (less useful, it will be very big due to a lot of
		979	encodings built-in that increase download times and are rarely used).
		980
		981	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		982
		983	It should be, starting with release 7.1. You are encouraged to properly
		984	install urxvt with privileges necessary for your OS now.
		985
		986	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		987	into a helper process for privileged operations (pty handling on some
		988	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		989	immediately. This is much safer than most other terminals that keep
		990	privileges while running (but is more relevant to urxvt, as it contains
		991	things as perl interpreters, which might be "helpful" to attackers).
		992
		993	This forking is done as the very first within main(), which is very early
		994	and reduces possible bugs to initialisation code run before main(), or
		995	things like the dynamic loader of your system, which should result in very
		996	little risk.
		997
		998	=head3 On Solaris 9, many line-drawing characters are too wide.
		999
		1000	Seems to be a known bug, read
		1001	L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
		1002	following ugly workaround to get non-double-wide-characters working:
		1003
		1004	#define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
		1005
		1006	=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
		1007
		1008	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
		1009	in your compile environment, or an implementation that implements it,
		1010	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
		1011	B<wchar_t> is represented as unicode.
		1012
		1013	As you might have guessed, FreeBSD does neither define this symobl nor
		1014	does it support it. Instead, it uses it's own internal representation of
		1015	B<wchar_t>. This is, of course, completely fine with respect to standards.
		1016
		1017	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		1018	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
		1019
		1020	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		1021	apps in an OS, as using a locale-dependent (and non-standardized)
		1022	representation of B<wchar_t> makes it impossible to convert between
		1023	B<wchar_t> (as used by X11 and your applications) and any other encoding
		1024	without implementing OS-specific-wrappers for each and every locale. There
		1025	simply are no APIs to convert B<wchar_t> into anything except the current
		1026	locale encoding.
		1027
		1028	Some applications (such as the formidable B<mlterm>) work around this
		1029	by carrying their own replacement functions for character set handling
		1030	with them, and either implementing OS-dependent hacks or doing multiple
		1031	conversions (which is slow and unreliable in case the OS implements
		1032	encodings slightly different than the terminal emulator).
		1033
		1034	The rxvt-unicode author insists that the right way to fix this is in the
		1035	system libraries once and for all, instead of forcing every app to carry
		1036	complete replacements for them :)
		1037
		1038	=head3 I use Solaris 9 and it doesn't compile/work/etc.
		1039
		1040	Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
		1041	problems with C<wcwidth> and a compile problem.
		1042
		1043	=head3 How can I use rxvt-unicode under cygwin?
		1044
		1045	rxvt-unicode should compile and run out of the box on cygwin, using
		1046	the X11 libraries that come with cygwin. libW11 emulation is no
		1047	longer supported (and makes no sense, either, as it only supported a
		1048	single font). I recommend starting the X-server in C<-multiwindow> or
		1049	C<-rootless> mode instead, which will result in similar look&feel as the
		1050	old libW11 emulation.
		1051
		1052	At the time of this writing, cygwin didn't seem to support any multi-byte
		1053	encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
		1054	to 8-bit encodings.

1395	B<< The exact syntax used is I<almost> solidified. >>
1396	In the menus, B<DON'T> try to use menuBar commands that add or remove a
1397	menuBar.
1398
1399	Note that in all of the commands, the B<< I</path/> >> I<cannot> be
1400	omitted: use B<./> to specify a menu relative to the current menu.
1401
1402	=head2 Overview of menuBar operation
1403
1404	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1405	of C<Pt> can be used for a variety of tasks:
1406
1407	At the top level is the current menuBar which is a member of a circular
1408	linked-list of other such menuBars.
1409
1410	The menuBar acts as a parent for the various drop-down menus, which in
1411	turn, may have labels, separator lines, menuItems and subMenus.
1412
1413	The menuItems are the useful bits: you can use them to mimic keyboard
1414	input or even to send text or escape sequences back to rxvt.
1415
1416	The menuBar syntax is intended to provide a simple yet robust method of
1417	constructing and manipulating menus and navigating through the
1418	menuBars.
1419
1420	The first step is to use the tag B<< [menu:I<name>] >> which creates
1421	the menuBar called I<name> and allows access. You may now or menus,
1422	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1423	menuBar access as B<readonly> to prevent accidental corruption of the
1424	menus. To re-access the current menuBar for alterations, use the tag
1425	B<[menu]>, make the alterations and then use B<[done]>

1436	is created, it is called I<name> (max of 15 chars) and the current
1437	menuBar is pushed onto the stack

1446	following format specifiers:
1447	B<%%> : literal B<%> character

1459	appended if required.) Start reading at a line with B<[menu]> or B<<
1460	[menu:+I<name> >> and continuing until B<[done]> is encountered.
1461
1462	Blank and comment lines (starting with B<#>) are ignored. Actually,
1463	since any invalid menu commands are also ignored, almost anything could
1464	be construed as a comment line, but this may be tightened up in the
1465	future ... so don't count on it!.

1596	the first of which will be stripped off and the balance directed to the

1600
1601	As a convenience for the many Emacs-type editors, I<action> may start
