		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 How can I keep rxvt-unicode from using reverse video so much?
195
196	First of all, make sure you are running with the right terminfo
197	(C<urxvt>), which will get rid of most of these effects. Then make sure
198	you have specified colours for italic and bold, as otherwise rxvt-unicode
199	might use reverse video to simulate the effect:
200
201	URxvt*colorBD: white
202	URxvt*colorIT: green
203
204	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
205
206	For some unexplainable reason, some programs (i.e. irssi) assume a very
207	weird colour palette when confronted with a terminal with more than the
208	standard 8 colours (rxvt-unicode supports 88). The right fix is, of
209	course, to fix these programs not to assume non-ISO colours without very
210	good reasons.
211
212	In the meantime, you can either edit your C<urxvt> terminfo definition to
213	only claim 8 colour support or use C<TERM=rxvt>, which will fix colours
214	but keep you from using other rxvt-unicode features.
215
216	=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
217
218	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
219	in your compile environment, or an implementation that implements it,
220	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
221	B<wchar_t> is represented as unicode.
222
223	As you might have guessed, FreeBSD does neither define this symobl nor
224	does it support it. Instead, it uses it's own internal representation of
225	B<wchar_t>. This is, of course, completely legal.
226
227	However, C<__STDC_ISO_10646__> is the only sane way to support
228	multi-language apps in an OS, as using a locale-dependent (and
229	non-standardized) representation of B<wchar_t> makes it impossible to
230	convert between B<wchar_t> (as used by X11 and your applications) and any
231	other encoding without implementing OS-specific-wrappers for each and
232	every locale. There simply are no APIs to convert B<wchar_t> into anything
233	except the current locale encoding.
234
235	Some applications (such as the formidable B<mlterm>) work around this
236	by carrying their own replacement functions for character set handling
237	with them, and either implementing OS-dependent hacks or doing multiple
238	conversions (which is slow and unreliable in case the OS implements
239	encodings slightly different than the terminal emulator).
240
241	The rxvt-unicode author insists that the right way to fix this is in the
242	system libraries once and for all, instead of forcing every app to carry
243	complete replacements.
244
245	=item How does rxvt-unicode determine the encoding to use?
246
247	=item Is there an option to switch encodings?
248
249	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
250	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
251	UTF-8 or any other encodings with respect to terminal I/O.
252
253	The reasons is that there exists a perfectly fine mechanism for selecting
254	the encoding, doing I/O and (most important) communicating this to all
255	applications so everybody agrees on character properties such as width and
256	code number. This mechanism is the I<locale>.
257
258	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
259	programs doing the same (that is, most) will automatically agree in the
260	interpretation of characters.
261
262	Unfortunately, there is no system-independent way to select locales, nor
263	is there a standard on how locale specifiers will look like.
264
265	On most systems, the content of the C<LC_CTYPE> environment variable
266	contains an arbitrary string which corresponds to an already-installed
267	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
268	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
269	(i.e. C<de> or C<german>) are also common.
270
271	Rxvt-unicode ignores all other locale categories, and except for
272	the encoding, ignores country or language-specific settings,
273	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the same for rxvt-unicode.
274
275	If you want to use a specific encoding you have to make sure you start
276	rxvt-unicode with the correct C<LC_CTYPE> category.
277
278	=item Can I switch locales at runtime?
279
280	Yes, using an escape sequence. Try sth. like this, which sets
281	rxvt-unicode's idea of C<LC_CTYPE>.
282
283	printf '\e]701;%s\007' ja_JP.SJIS
284
285	See also the previous question.
286
287	Sometimes this capability is rather handy when you want to work in one
288	locale (e.g. C<de_DE.UTF-8>) but some programs don't support UTF-8. For
289	example, I use this script to start C<xjdic>, which first switches to a
290	locale supported by xjdic and back later:
291
292	printf '\e]701;%s\007' ja_JP.SJIS
293	xjdic -js
294	printf '\e]701;%s\007' de_DE.UTF-8
295
296	=item Can I switch the fonts at runtime?
297
298	Yes, using an escape sequence. Try sth. like this, which has the same
299	effect as using the C<-fn> switch, and takes effect immediately:
300
301	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
302
303	This is useful if you e.g. work primarily with japanese (and prefer a
304	japanese font), but you have to switch to chinese temporarily, where
305	japanese fonts would only be in your way.
306
307	You can think of this as a kind of manual ISO-2022 switching.
308
309	=item Why do italic characters look as if clipped?
310
311	Many fonts have difficulties with italic characters and hinting. For
312	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
313	Mono> completely fails in it's italic face. A workaround is to enable
314	freetype autohinting, i.e. like this:
315
316	URxvt*italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
317	URxvt*boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
318
319	=item My input method wants <some encoding> but I want UTF-8, what can I do?
320
321	You can specify separate locales for the input method and the rest of the
322	terminal, using the resource C<imlocale>:
323
324	URxvt*imlocale: ja_JP.EUC-JP
325
326	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
327	use your input method. Please note, however, that you will not be able to
328	input characters outside C<EUC-JP> in a normal way then, as your input
329	method limits you.

		79
		80	The original rxvt and rxvt-unicode always export the variable "COLORTERM",
		81	so you can check and see if that is set. Note that several programs, JED,

		83	whether or not to use color.
		84
		85	=head3 How do I set the correct, full IP address for the DISPLAY variable?
		86
		87	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		88	insecure mode then it is possible to use the following shell script
		89	snippets to correctly set the display. If your version of rxvt-unicode
		90	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		91	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		92	regular xterm.

		110	=head3 How do I compile the manual pages on my own?
		111
		112	You need to have a recent version of perl installed as F</usr/bin/perl>,
		113	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
		114	the doc subdirectory and enter C<make alldoc>.
		115
		116	=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
		117
		118	I often get asked about this, and I think, no, they didn't cause extra
		119	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		120	that the urxvt binary is larger (due to some encoding tables always being
		121	compiled in), but it actually uses less memory (RSS) after startup. Even
		122	with C<--disable-everything>, this comparison is a bit unfair, as many
		123	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		124	already in use in this mode.
		125
		126	text data bss drs rss filename
		127	98398 1664 24 15695 1824 rxvt --disable-everything
		128	188985 9048 66616 18222 1788 urxvt --disable-everything
		129
		130	When you C<--enable-everything> (which _is_ unfair, as this involves xft
		131	and full locale/XIM support which are quite bloaty inside libX11 and my
		132	libc), the two diverge, but not unreasnobaly so.
		133
		134	text data bss drs rss filename
		135	163431 2152 24 20123 2060 rxvt --enable-everything
		136	1035683 49680 66648 29096 3680 urxvt --enable-everything
		137
		138	The very large size of the text section is explained by the east-asian
		139	encoding tables, which, if unused, take up disk space but nothing else
		140	and can be compiled out unless you rely on X11 core fonts that use those
		141	encodings. The BSS size comes from the 64k emergency buffer that my c++
		142	compiler allocates (but of course doesn't use unless you are out of
		143	memory). Also, using an xft font instead of a core font immediately adds a
		144	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		145	not used.
		146
		147	Of course, due to every character using two or four bytes instead of one,
		148	a large scrollback buffer will ultimately make rxvt-unicode use more
		149	memory.
		150
		151	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		152	still fares rather well. And compared to some monsters like gnome-terminal
		153	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		154	43180k in daemons that stay around after exit, plus half a minute of
		155	startup time, including the hundreds of warnings it spits out), it fares
		156	extremely well g.
		157
		158	=head3 Why C++, isn't that unportable/bloated/uncool?
		159
		160	Is this a question? :) It comes up very often. The simple answer is: I had
		161	to write it, and C++ allowed me to write and maintain it in a fraction
		162	of the time and effort (which is a scarce resource for me). Put even
		163	shorter: It simply wouldn't exist without C++.
		164
		165	My personal stance on this is that C++ is less portable than C, but in
		166	the case of rxvt-unicode this hardly matters, as its portability limits
		167	are defined by things like X11, pseudo terminals, locale support and unix
		168	domain sockets, which are all less portable than C++ itself.
		169
		170	Regarding the bloat, see the above question: It's easy to write programs
		171	in C that use gobs of memory, an certainly possible to write programs in
		172	C++ that don't. C++ also often comes with large libraries, but this is
		173	not necessarily the case with GCC. Here is what rxvt links against on my
		174	system with a minimal config:
		175
		176	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		177	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		178	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		179	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		180
		181	And here is rxvt-unicode:
		182
		183	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		184	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		185	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		186	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		187	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		188
		189	No large bloated libraries (of course, none were linked in statically),
		190	except maybe libX11 :)

		193	=head2 Rendering, Font & Look and Feel Issues
		194
		195	=head3 I can't get transparency working, what am I doing wrong?
		196
		197	First of all, transparency isn't officially supported in rxvt-unicode, so
		198	you are mostly on your own. Do not bug the author about it (but you may
		199	bug everybody else). Also, if you can't get it working consider it a rite
		200	of passage: ... and you failed.
		201
		202	Here are four ways to get transparency. B<Do> read the manpage and option
		203	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		204
		205	1. Use inheritPixmap:
		206
		207	Esetroot wallpaper.jpg
		208	@@URXVT_NAME@@ -ip -tint red -sh 40
		209
		210	That works. If you think it doesn't, you lack transparency and tinting
		211	support, or you are unable to read.
		212
		213	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		214	to use effects other than tinting and shading: Just shade/tint/whatever
		215	your picture with gimp or any other tool:
		216
		217	convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
		218	@@URXVT_NAME@@ -pixmap background.xpm -pe automove-background
		219
		220	That works. If you think it doesn't, you lack XPM and Perl support, or you
		221	are unable to read.
		222
		223	3. Use an ARGB visual:
		224
		225	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		226
		227	This requires XFT support, and the support of your X-server. If that
		228	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		229	there yet, no matter what they claim. Rxvt-Unicode contains the neccessary
		230	bugfixes and workarounds for Xft and Xlib to make it work, but that
		231	doesn't mean that your WM has the required kludges in place.
		232
		233	4. Use xcompmgr and let it do the job:
		234
		235	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		236	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		237
		238	Then click on a window you want to make transparent. Replace C<0xc0000000>
		239	by other values to change the degree of opacity. If it doesn't work and
		240	your server crashes, you got to keep the pieces.
		241
		242	=head3 Why do some chinese characters look so different than others?
		243
		244	This is because there is a difference between script and language --
		245	rxvt-unicode does not know which language the text that is output is,
		246	as it only knows the unicode character codes. If rxvt-unicode first
		247	sees a japanese/chinese character, it might choose a japanese font for
		248	display. Subsequent japanese characters will use that font. Now, many
		249	chinese characters aren't represented in japanese fonts, so when the first
		250	non-japanese character comes up, rxvt-unicode will look for a chinese font
		251	-- unfortunately at this point, it will still use the japanese font for
		252	chinese characters that are also in the japanese font.
		253
		254	The workaround is easy: just tag a chinese font at the end of your font
		255	list (see the previous question). The key is to view the font list as
		256	a preference list: If you expect more japanese, list a japanese font
		257	first. If you expect more chinese, put a chinese font first.
		258
		259	In the future it might be possible to switch language preferences at
		260	runtime (the internal data structure has no problem with using different
		261	fonts for the same character at the same time, but no interface for this
		262	has been designed yet).
		263
		264	Until then, you might get away with switching fonts at runtime (see L<Can
		265	I switch the fonts at runtime?> later in this document).
		266
		267	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		268
		269	Most fonts were not designed for terminal use, which means that character
		270	size varies a lot. A font that is otherwise fine for terminal use might
		271	contain some characters that are simply too wide. Rxvt-unicode will avoid
		272	these characters. For characters that are just "a bit" too wide a special
		273	"careful" rendering mode is used that redraws adjacent characters.
		274
		275	All of this requires that fonts do not lie about character sizes,
		276	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		277	box, and rxvt-unicode has no way of detecting this (the correct way is to
		278	ask for the character bounding box, which unfortunately is wrong in these
		279	cases).
		280
		281	It's not clear (to me at least), wether this is a bug in Xft, freetype,
		282	or the respective font. If you encounter this problem you might try using
		283	the C<-lsp> option to give the font more height. If that doesn't work, you
		284	might be forced to use a different font.
		285
		286	All of this is not a problem when using X11 core fonts, as their bounding
		287	box data is correct.
		288
		289	=head3 How can I keep rxvt-unicode from using reverse video so much?
		290
		291	First of all, make sure you are running with the right terminal settings
		292	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		293	make sure you have specified colours for italic and bold, as otherwise
		294	rxvt-unicode might use reverse video to simulate the effect:
		295
		296	URxvt.colorBD: white
		297	URxvt.colorIT: green
		298
		299	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		300
		301	For some unexplainable reason, some rare programs assume a very weird
		302	colour palette when confronted with a terminal with more than the standard
		303	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		304	these programs not to assume non-ISO colours without very good reasons.
		305
		306	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		307	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		308	fix colours but keep you from using other rxvt-unicode features.
		309
		310	=head3 Can I switch the fonts at runtime?
		311
		312	Yes, using an escape sequence. Try something like this, which has the same
		313	effect as using the C<-fn> switch, and takes effect immediately:
		314
		315	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
		316
		317	This is useful if you e.g. work primarily with japanese (and prefer a
		318	japanese font), but you have to switch to chinese temporarily, where
		319	japanese fonts would only be in your way.
		320
		321	You can think of this as a kind of manual ISO-2022 switching.
		322
		323	=head3 Why do italic characters look as if clipped?
		324
		325	Many fonts have difficulties with italic characters and hinting. For
		326	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		327	Mono> completely fails in it's italic face. A workaround might be to
		328	enable freetype autohinting, i.e. like this:
		329
		330	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		331	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true

		415	=head3 Why do some characters look so much different than others?
		416
		417	See next entry.
		418
		419	=head3 How does rxvt-unicode choose fonts?
		420
		421	Most fonts do not contain the full range of Unicode, which is
		422	fine. Chances are that the font you (or the admin/package maintainer of
		423	your system/os) have specified does not cover all the characters you want
		424	to display.
		425
		426	B<rxvt-unicode> makes a best-effort try at finding a replacement
		427	font. Often the result is fine, but sometimes the chosen font looks
		428	bad/ugly/wrong. Some fonts have totally strange characters that don't
		429	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		430	intelligence to detect that a specific glyph is wrong: it has to believe
		431	the font that the characters it claims to contain indeed look correct.
		432
		433	In that case, select a font of your taste and add it to the font list,
		434	e.g.:
		435
		436	@@URXVT_NAME@@ -fn basefont,font2,font3...
		437
		438	When rxvt-unicode sees a character, it will first look at the base
		439	font. If the base font does not contain the character, it will go to the
		440	next font, and so on. Specifying your own fonts will also speed up this
		441	search and use less resources within rxvt-unicode and the X-server.
		442
		443	The only limitation is that none of the fonts may be larger than the base
		444	font, as the base font defines the terminal character cell size, which
		445	must be the same due to the way terminals work.
		446
		447
		448	=head2 Keyboard, Mouse & User Interaction
		449
		450	=head3 The new selection selects pieces that are too big, how can I select single words?
		451
		452	If you want to select e.g. alphanumeric words, you can use the following
		453	setting:
		454
		455	URxvt.selection.pattern-0: ([[:word:]]+)
		456
		457	If you click more than twice, the selection will be extended
		458	more and more.
		459
		460	To get a selection that is very similar to the old code, try this pattern:
		461
		462	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{\|})]+)
		463
		464	Please also note that the I<LeftClick Shift-LeftClik> combination also
		465	selects words like the old code.
		466
		467	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		468
		469	You can disable the perl extension completely by setting the
		470	B<perl-ext-common> resource to the empty string, which also keeps
		471	rxvt-unicode from initialising perl, saving memory.
		472
		473	If you only want to disable specific features, you first have to
		474	identify which perl extension is responsible. For this, read the section
		475	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		476	example, to disable the B<selection-popup> and B<option-popup>, specify
		477	this B<perl-ext-common> resource:
		478
		479	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		480
		481	This will keep the default extensions, but disable the two popup
		482	extensions. Some extensions can also be configured, for example,
		483	scrollback search mode is triggered by B<M-s>. You can move it to any
		484	other combination either by setting the B<searchable-scrollback> resource:
		485
		486	URxvt.searchable-scrollback: CM-s

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

		490	See next entry.
		491
		492	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		493
		494	These are caused by the C<readline> perl extension. Under normal
		495	circumstances, it will move your cursor around when you click into the

		519	your input method (e.g. the default input method handling Compose keys)

606		676
607	# change the locale and tell rxvt-unicode about it	677	... or by installing rxvt-unicode normally on the remote system,
608	export LC_CTYPE=ja_JP.EUC-JP; printf "\33]701;$LC_CTYPE\007"
609		678
610	# set window title	679	If you cannot or do not want to do this, then you can simply set
611	printf '\33]2;%s\007' "new window title"	680	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		681	problems arising, which includes wrong keymapping, less and different
		682	colours and some refresh errors in fullscreen applications. It's a nice
		683	quick-and-dirty workaround for rare cases, though.
		684
		685	If you always want to do this (and are fine with the consequences) you
		686	can either recompile rxvt-unicode with the desired TERM value or use a
		687	resource to set it:
		688
		689	URxvt.termName: rxvt
		690
		691	If you don't plan to use B<rxvt> (quite common...) you could also replace
		692	the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
		693
		694	=head3 C<tic> outputs some error when compiling the terminfo entry.
		695
		696	Most likely it's the empty definition for C<enacs=>. Just replace it by
		697	C<enacs=\E[0@> and try again.

		701	See next entry.
		702
		703	=head3 I need a termcap file entry.
		704
		705	One reason you might want this is that some distributions or operating

		707	library (Fedora Core's bash is one example) and rely on a termcap entry
		708	for C<rxvt-unicode>.
		709
		710	You could use rxvt's termcap entry with resonable results in many cases.
		711	You can also create a termcap entry by using terminfo's infocmp program
		712	like this:
		713
		714	infocmp -C rxvt-unicode
		715
		716	Or you could use this termcap entry, generated by the command above:

		745
		746	TERM rxvt-unicode
		747
		748	to C</etc/DIR_COLORS> or simply add:
		749
		750	alias ls='ls --color=auto'

		759
		760	See next entry.
		761
		762	=head3 Why are the secondary screen-related options not working properly?
		763
		764	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		765	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		766	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		767	features. Unfortunately, some of these (most notably, again, Debian
		768	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		769	file, so you will need to install it on your own (See the question B<When
		770	I log-in to another system it tells me about missing terminfo data?> on
		771	how to do this).

		777
		778	See next entry.
		779
		780	=head3 Unicode does not seem to work?
		781
		782	If you encounter strange problems like typing an accented character but
		783	getting two unrelated other characters or similar, or if program output is
		784	subtly garbled, then you should check your locale settings.
		785
		786	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		787	programs. Often rxvt-unicode is started in the C<C> locale, while the
		788	login script running within the rxvt-unicode window changes the locale to
		789	something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
		790
		791	The best thing is to fix your startup environment, as you will likely run
		792	into other problems. If nothing works you can try this in your .profile.
		793
		794	printf '\e]701;%s\007' "$LC_CTYPE"
		795
		796	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		797	supported on your systems. Some systems have a C<locale> command which
		798	displays this (also, C<perl -e0> can be used to check locale settings, as
		799	it will complain loudly if it cannot set the locale). If it displays something
		800	like:
		801
		802	locale: Cannot set LC_CTYPE to default locale: ...
		803
		804	Then the locale you specified is not supported on your system.
		805
		806	If nothing works and you are sure that everything is set correctly then
		807	you will need to remember a little known fact: Some programs just don't
		808	support locales :(
		809
		810	=head3 How does rxvt-unicode determine the encoding to use?
		811
		812	See next entry.
		813
		814	=head3 Is there an option to switch encodings?
		815
		816	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		817	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		818	UTF-8 or any other encodings with respect to terminal I/O.
		819
		820	The reasons is that there exists a perfectly fine mechanism for selecting
		821	the encoding, doing I/O and (most important) communicating this to all
		822	applications so everybody agrees on character properties such as width
		823	and code number. This mechanism is the I<locale>. Applications not using
		824	that info will have problems (for example, C<xterm> gets the width of
		825	characters wrong as it uses it's own, locale-independent table under all
		826	locales).
		827
		828	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		829	programs doing the same (that is, most) will automatically agree in the
		830	interpretation of characters.
		831
		832	Unfortunately, there is no system-independent way to select locales, nor
		833	is there a standard on how locale specifiers will look like.
		834
		835	On most systems, the content of the C<LC_CTYPE> environment variable
		836	contains an arbitrary string which corresponds to an already-installed
		837	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		838	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		839	(i.e. C<de> or C<german>) are also common.
		840
		841	Rxvt-unicode ignores all other locale categories, and except for
		842	the encoding, ignores country or language-specific settings,
		843	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		844	rxvt-unicode.
		845
		846	If you want to use a specific encoding you have to make sure you start
		847	rxvt-unicode with the correct C<LC_CTYPE> category.
		848
		849	=head3 Can I switch locales at runtime?
		850
		851	Yes, using an escape sequence. Try something like this, which sets
		852	rxvt-unicode's idea of C<LC_CTYPE>.
		853
		854	printf '\e]701;%s\007' ja_JP.SJIS
		855
		856	See also the previous answer.
		857
		858	Sometimes this capability is rather handy when you want to work in
		859	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		860	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		861	first switches to a locale supported by xjdic and back later:
		862
		863	printf '\e]701;%s\007' ja_JP.SJIS
		864	xjdic -js
		865	printf '\e]701;%s\007' de_DE.UTF-8
		866
		867	You can also use xterm's C<luit> program, which usually works fine, except
		868	for some locales where character width differs between program- and
		869	rxvt-unicode-locales.
		870
		871	=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
		872
		873	You can specify separate locales for the input method and the rest of the
		874	terminal, using the resource C<imlocale>:
		875
		876	URxvt.imlocale: ja_JP.EUC-JP
		877
		878	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		879	use your input method. Please note, however, that you will not be able to
		880	input characters outside C<EUC-JP> in a normal way then, as your input
		881	method limits you.
		882
		883	=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
		884
		885	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		886	design. Applications can avoid some crashes at the expense of memory
		887	leaks, and Input Methods can avoid some crashes by careful ordering at
		888	exit time. B<kinput2> (and derived input methods) generally succeeds,
		889	while B<SCIM> (or similar input methods) fails. In the end, however,
		890	crashes cannot be completely avoided even if both sides cooperate.
		891
		892	So the only workaround is not to kill your Input Method Servers.
		893
		894
		895	=head2 Operating Systems / Package Maintaining
		896
		897	=head3 I am using Debian GNU/Linux and have a problem...
		898
		899	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		900	patches that considerably change the behaviour of rxvt-unicode (but
		901	unfortunately this notice has been removed). Before reporting a bug to
		902	the original rxvt-unicode author please download and install the genuine
		903	version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
		904	the problem. If you cannot, chances are that the problems are specific to
		905	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		906	Tracking System (use C<reportbug> to report the bug).
		907
		908	For other problems that also affect the Debian package, you can and
		909	probably should use the Debian BTS, too, because, after all, it's also a
		910	bug in the Debian version and it serves as a reminder for other users that
		911	might encounter the same issue.
		912
		913	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		914
		915	You should build one binary with the default options. F<configure>
		916	now enables most useful options, and the trend goes to making them
		917	runtime-switchable, too, so there is usually no drawback to enbaling them,
		918	except higher disk and possibly memory usage. The perl interpreter should
		919	be enabled, as important functionality (menus, selection, likely more in
		920	the future) depends on it.
		921
		922	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		923	system-wide (except maybe with C<defaults>). This will result in useful
		924	behaviour. If your distribution aims at low memory, add an empty
		925	C<perl-ext-common> resource to the app-defaults file. This will keep the
		926	perl interpreter disabled until the user enables it.
		927
		928	If you can/want build more binaries, I recommend building a minimal
		929	one with C<--disable-everything> (very useful) and a maximal one with
		930	C<--enable-everything> (less useful, it will be very big due to a lot of
		931	encodings built-in that increase download times and are rarely used).
		932
		933	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		934
		935	It should be, starting with release 7.1. You are encouraged to properly
		936	install urxvt with privileges necessary for your OS now.
		937
		938	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		939	into a helper process for privileged operations (pty handling on some
		940	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		941	immediately. This is much safer than most other terminals that keep
		942	privileges while running (but is more relevant to urxvt, as it contains
		943	things as perl interpreters, which might be "helpful" to attackers).
		944
		945	This forking is done as the very first within main(), which is very early
		946	and reduces possible bugs to initialisation code run before main(), or
		947	things like the dynamic loader of your system, which should result in very
		948	little risk.
		949
		950	=head3 On Solaris 9, many line-drawing characters are too wide.
		951
		952	Seems to be a known bug, read
		953	L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
		954	following ugly workaround to get non-double-wide-characters working:
		955
		956	#define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
		957
		958	=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
		959
		960	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
		961	in your compile environment, or an implementation that implements it,
		962	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
		963	B<wchar_t> is represented as unicode.
		964
		965	As you might have guessed, FreeBSD does neither define this symobl nor
		966	does it support it. Instead, it uses it's own internal representation of
		967	B<wchar_t>. This is, of course, completely fine with respect to standards.
		968
		969	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		970	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
		971
		972	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		973	apps in an OS, as using a locale-dependent (and non-standardized)
		974	representation of B<wchar_t> makes it impossible to convert between
		975	B<wchar_t> (as used by X11 and your applications) and any other encoding
		976	without implementing OS-specific-wrappers for each and every locale. There
		977	simply are no APIs to convert B<wchar_t> into anything except the current
		978	locale encoding.
		979
		980	Some applications (such as the formidable B<mlterm>) work around this
		981	by carrying their own replacement functions for character set handling
		982	with them, and either implementing OS-dependent hacks or doing multiple
		983	conversions (which is slow and unreliable in case the OS implements
		984	encodings slightly different than the terminal emulator).
		985
		986	The rxvt-unicode author insists that the right way to fix this is in the
		987	system libraries once and for all, instead of forcing every app to carry
		988	complete replacements for them :)
		989
		990	=head3 I use Solaris 9 and it doesn't compile/work/etc.
		991
		992	Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
		993	problems with C<wcwidth> and a compile problem.
		994
		995	=head3 How can I use rxvt-unicode under cygwin?
		996
		997	rxvt-unicode should compile and run out of the box on cygwin, using
		998	the X11 libraries that come with cygwin. libW11 emulation is no
		999	longer supported (and makes no sense, either, as it only supported a
		1000	single font). I recommend starting the X-server in C<-multiwindow> or
		1001	C<-rootless> mode instead, which will result in similar look&feel as the
		1002	old libW11 emulation.
		1003
		1004	At the time of this writing, cygwin didn't seem to support any multi-byte
		1005	encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
		1006	to 8-bit encodings.

1387	B<< The exact syntax used is I<almost> solidified. >>
1388	In the menus, B<DON'T> try to use menuBar commands that add or remove a
1389	menuBar.
1390
1391	Note that in all of the commands, the B<< I</path/> >> I<cannot> be
1392	omitted: use B<./> to specify a menu relative to the current menu.
1393
1394	=head2 Overview of menuBar operation
1395
1396	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
1397	of C<Pt> can be used for a variety of tasks:
1398
1399	At the top level is the current menuBar which is a member of a circular
1400	linked-list of other such menuBars.
1401
1402	The menuBar acts as a parent for the various drop-down menus, which in
1403	turn, may have labels, separator lines, menuItems and subMenus.
1404
1405	The menuItems are the useful bits: you can use them to mimic keyboard
1406	input or even to send text or escape sequences back to rxvt.
1407
1408	The menuBar syntax is intended to provide a simple yet robust method of
1409	constructing and manipulating menus and navigating through the
1410	menuBars.
1411
1412	The first step is to use the tag B<< [menu:I<name>] >> which creates
1413	the menuBar called I<name> and allows access. You may now or menus,
1414	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
1415	menuBar access as B<readonly> to prevent accidental corruption of the
1416	menus. To re-access the current menuBar for alterations, use the tag
1417	B<[menu]>, make the alterations and then use B<[done]>

1428	is created, it is called I<name> (max of 15 chars) and the current
1429	menuBar is pushed onto the stack

1451	appended if required.) Start reading at a line with B<[menu]> or B<<
1452	[menu:+I<name> >> and continuing until B<[done]> is encountered.
1453
1454	Blank and comment lines (starting with B<#>) are ignored. Actually,
1455	since any invalid menu commands are also ignored, almost anything could
1456	be construed as a comment line, but this may be tightened up in the
1457	future ... so don't count on it!.
