		32	=head3 My question isn't answered here, can I ask a human?
		33
		34	Before sending me mail, you could go to IRC: C<irc.freenode.net>,
		35	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
		36	interested in learning about new and exciting problems (but not FAQs :).
		37
		38	=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
		39
		40	Beginning with version 7.3, there is a perl extension that implements a
		41	simple tabbed terminal. It is installed by default, so any of these should
		42	give you tabs:
		43
		44	@@URXVT_NAME@@ -pe tabbed
		45
		46	URxvt.perl-ext-common: default,tabbed
		47
		48	It will also work fine with tabbing functionality of many window managers
		49	or similar tabbing programs, and its embedding-features allow it to be
		50	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
		51	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
		52	(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:
50

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.

		76	=head3 How can I start @@URXVT_NAME@@d in a race-free way?
		77
		78	Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
		79	display, create the listening socket and then fork.
		80
		81	=head3 How can I start @@URXVT_NAME@@d automatically when I run @@URXVT_NAME@@c?
		82
		83	If you want to start @@URXVT_NAME@@d automatically whenever you run
		84	@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
		85
		86	#!/bin/sh
		87	@@URXVT_NAME@@c "$@"
		88	if [ $? -eq 2 ]; then
		89	@@URXVT_NAME@@d -q -o -f
		90	@@URXVT_NAME@@c "$@"
		91	fi
		92
		93	This tries to create a new terminal, and if fails with exit status 2,
		94	meaning it couldn't connect to the daemon, it will start the daemon and
		95	re-run the command. Subsequent invocations of the script will re-use the
		96	existing daemon.
		97
		98	=head3 How do I distinguish whether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
		99
		100	The original rxvt and rxvt-unicode always export the variable "COLORTERM",
		101	so you can check and see if that is set. Note that several programs, JED,
		102	slrn, Midnight Commander automatically check this variable to decide
		103	whether or not to use color.
		104
		105	=head3 How do I set the correct, full IP address for the DISPLAY variable?
		106
		107	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		108	insecure mode then it is possible to use the following shell script
		109	snippets to correctly set the display. If your version of rxvt-unicode
		110	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		111	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		112	regular xterm.

		130	=head3 How do I compile the manual pages on my own?
		131
		132	You need to have a recent version of perl installed as F</usr/bin/perl>,
		133	one that comes with F<pod2man>, F<pod2text> and F<pod2xhtml> (from
		134	F<Pod::Xhtml>). Then go to the doc subdirectory and enter C<make alldoc>.
		135
		136	=head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
		137
		138	I often get asked about this, and I think, no, they didn't cause extra
		139	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		140	that the urxvt binary is larger (due to some encoding tables always being
		141	compiled in), but it actually uses less memory (RSS) after startup. Even
		142	with C<--disable-everything>, this comparison is a bit unfair, as many
		143	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		144	already in use in this mode.
		145
		146	text data bss drs rss filename
		147	98398 1664 24 15695 1824 rxvt --disable-everything
		148	188985 9048 66616 18222 1788 urxvt --disable-everything
		149
		150	When you C<--enable-everything> (which I<is> unfair, as this involves xft
		151	and full locale/XIM support which are quite bloaty inside libX11 and my
		152	libc), the two diverge, but not unreasonably so.
		153
		154	text data bss drs rss filename
		155	163431 2152 24 20123 2060 rxvt --enable-everything
		156	1035683 49680 66648 29096 3680 urxvt --enable-everything
		157
		158	The very large size of the text section is explained by the east-asian
		159	encoding tables, which, if unused, take up disk space but nothing else
		160	and can be compiled out unless you rely on X11 core fonts that use those
		161	encodings. The BSS size comes from the 64k emergency buffer that my c++
		162	compiler allocates (but of course doesn't use unless you are out of
		163	memory). Also, using an xft font instead of a core font immediately adds a
		164	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		165	not used.
		166
		167	Of course, due to every character using two or four bytes instead of one,
		168	a large scrollback buffer will ultimately make rxvt-unicode use more
		169	memory.
		170
		171	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		172	still fares rather well. And compared to some monsters like gnome-terminal
		173	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		174	43180k in daemons that stay around after exit, plus half a minute of
		175	startup time, including the hundreds of warnings it spits out), it fares
		176	extremely well g.
		177
		178	=head3 Why C++, isn't that unportable/bloated/uncool?
		179
		180	Is this a question? :) It comes up very often. The simple answer is: I had
		181	to write it, and C++ allowed me to write and maintain it in a fraction
		182	of the time and effort (which is a scarce resource for me). Put even
		183	shorter: It simply wouldn't exist without C++.
		184
		185	My personal stance on this is that C++ is less portable than C, but in
		186	the case of rxvt-unicode this hardly matters, as its portability limits
		187	are defined by things like X11, pseudo terminals, locale support and unix
		188	domain sockets, which are all less portable than C++ itself.
		189
		190	Regarding the bloat, see the above question: It's easy to write programs
		191	in C that use gobs of memory, an certainly possible to write programs in
		192	C++ that don't. C++ also often comes with large libraries, but this is
		193	not necessarily the case with GCC. Here is what rxvt links against on my
		194	system with a minimal config:
		195
		196	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		197	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		198	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		199	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		200
		201	And here is rxvt-unicode:
		202
		203	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		204	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		205	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		206	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		207	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		208
		209	No large bloated libraries (of course, none were linked in statically),
		210	except maybe libX11 :)

		213	=head2 Rendering, Font & Look and Feel Issues
		214
		215	=head3 I can't get transparency working, what am I doing wrong?
		216
		217	First of all, please address all transparency related issues to Sasha Vasko at
		218	sasha@aftercode.net and do not bug the author about it. Also, if you can't
		219	get it working consider it a rite of passage: ... and you failed.
		220
		221	Here are four ways to get transparency. B<Do> read the manpage and option
		222	descriptions for the programs mentioned and rxvt-unicode. Really, do it!
		223
		224	1. Use transparent mode:
		225
		226	Esetroot wallpaper.jpg
		227	@@URXVT_NAME@@ -tr -tint red -sh 40
		228
		229	That works. If you think it doesn't, you lack transparency and tinting
		230	support, or you are unable to read.
		231
		232	2. Use a simple pixmap and emulate pseudo-transparency. This enables you
		233	to use effects other than tinting and shading: Just shade/tint/whatever
		234	your picture with gimp or any other tool:
		235
		236	convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
		237	@@URXVT_NAME@@ -pixmap "background.jpg;:root"
		238
		239	That works. If you think it doesn't, you lack AfterImage support, or you
		240	are unable to read.
		241
		242	3. Use an ARGB visual:
		243
		244	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		245
		246	This requires XFT support, and the support of your X-server. If that
		247	doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
		248	there yet, no matter what they claim. Rxvt-Unicode contains the necessary
		249	bugfixes and workarounds for Xft and Xlib to make it work, but that
		250	doesn't mean that your WM has the required kludges in place.
		251
		252	4. Use xcompmgr and let it do the job:
		253
		254	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		255	-set _NET_WM_WINDOW_OPACITY 0xc0000000
		256
		257	Then click on a window you want to make transparent. Replace C<0xc0000000>
		258	by other values to change the degree of opacity. If it doesn't work and
		259	your server crashes, you got to keep the pieces.
		260
		261	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		262
		263	Most fonts were not designed for terminal use, which means that character
		264	size varies a lot. A font that is otherwise fine for terminal use might
		265	contain some characters that are simply too wide. Rxvt-unicode will avoid
		266	these characters. For characters that are just "a bit" too wide a special
		267	"careful" rendering mode is used that redraws adjacent characters.
		268
		269	All of this requires that fonts do not lie about character sizes,
		270	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		271	box, and rxvt-unicode has no way of detecting this (the correct way is to
		272	ask for the character bounding box, which unfortunately is wrong in these
		273	cases).
		274
		275	It's not clear (to me at least), whether this is a bug in Xft, freetype,
		276	or the respective font. If you encounter this problem you might try using
		277	the C<-lsp> option to give the font more height. If that doesn't work, you
		278	might be forced to use a different font.
		279
		280	All of this is not a problem when using X11 core fonts, as their bounding
		281	box data is correct.
		282
		283	=head3 How can I keep rxvt-unicode from using reverse video so much?
		284
		285	First of all, make sure you are running with the right terminal settings
		286	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		287	make sure you have specified colours for italic and bold, as otherwise
		288	rxvt-unicode might use reverse video to simulate the effect:
		289
		290	URxvt.colorBD: white
		291	URxvt.colorIT: green
		292
		293	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		294
		295	For some unexplainable reason, some rare programs assume a very weird
		296	colour palette when confronted with a terminal with more than the standard
		297	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		298	these programs not to assume non-ISO colours without very good reasons.
		299
		300	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		301	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		302	fix colours but keep you from using other rxvt-unicode features.
		303
		304	=head3 Can I switch the fonts at runtime?
		305
		306	Yes, using an escape sequence. Try something like this, which has the same
		307	effect as using the C<-fn> switch, and takes effect immediately:
		308
		309	printf '\33]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	=head3 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 its italic face. A workaround might be to
		322	enable 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

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

		478	setting:
		479
		480	URxvt.selection.pattern-0: ([[:word:]]+)
		481
		482	If you click more than twice, the selection will be extended
		483	more and more.

		487	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{\|})]+)
		488
		489	Please also note that the I<LeftClick Shift-LeftClick> combination also
		490	selects words like the old code.
		491
		492	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		493
		494	You can disable the perl extension completely by setting the
		495	B<perl-ext-common> resource to the empty string, which also keeps
		496	rxvt-unicode from initialising perl, saving memory.
		497
		498	If you only want to disable specific features, you first have to
		499	identify which perl extension is responsible. For this, read the section
		500	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		501	example, to disable the B<selection-popup> and B<option-popup>, specify
		502	this B<perl-ext-common> resource:
		503
		504	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		505
		506	This will keep the default extensions, but disable the two popup
		507	extensions. Some extensions can also be configured, for example,
		508	scrollback search mode is triggered by B<M-s>. You can move it to any
		509	other combination either by setting the B<searchable-scrollback> resource:
		510
		511	URxvt.searchable-scrollback: CM-s
		512
		513	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
		514
		515	See next entry.
		516
		517	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		518
		519	These are caused by the C<readline> perl extension. Under normal
		520	circumstances, it will move your cursor around when you click into the
		521	line that contains it. It tries hard not to do this at the wrong moment,
		522	but when running a program that doesn't parse cursor movements or in some
		523	cases during rlogin sessions, it fails to detect this properly.
		524
		525	You can permanently switch this feature off by disabling the C<readline>
		526	extension:
		527
		528	URxvt.perl-ext-common: default,-readline
		529
		530	=head3 My numerical keypad acts weird and generates differing output?
		531
		532	Some Debian GNUL/Linux users seem to have this problem, although no
		533	specific details were reported so far. It is possible that this is caused
		534	by the wrong C<TERM> setting, although the details of whether and how
		535	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		536	keymap. See the answer to the previous question, and please report if that
		537	helped.
		538
		539	=head3 My Compose (Multi_key) key is no longer working.
		540
		541	The most common causes for this are that either your locale is not set
		542	correctly, or you specified a B<preeditStyle> that is not supported by
		543	your input method. For example, if you specified B<OverTheSpot> and
		544	your input method (e.g. the default input method handling Compose keys)
		545	does not support this (for instance because it is not visual), then
		546	rxvt-unicode will continue without an input method.
		547
		548	In this case either do not specify a B<preeditStyle> or specify more than
		549	one pre-edit style, such as B<OverTheSpot,Root,None>.
		550
		551	=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		552
		553	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		554	international keyboards) or simply use ISO 14755 support to your
		555	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		556	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		557	character and so on.
		558
		559	=head3 Mouse cut/paste suddenly no longer works.
		560
		561	Make sure that mouse reporting is actually turned off since killing
		562	some editors prematurely may leave the mouse in mouse report mode. I've
		563	heard that tcsh may use mouse reporting unless it otherwise specified. A
		564	quick check is to see if cut/paste works when the Alt or Shift keys are
		565	depressed.

		776	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		777	font (different glyphs for C<;> and many other harmless characters),
		778	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		779	bold version has less chars than the medium version, so I use it for rare
		780	characters, too. When editing sources with vim, I use italic for comments
		781	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		782
		783	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		784	purposes, it works, and gives a different look, as my normal (Non-bold)

		804	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		805	stuff while keeping a very small window. If somebody pastes something
		806	complicated (e.g. japanese), I temporarily switch to a larger font.
		807
		808	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		809	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		810	file for different hosts, for example, on ym main desktop, I use:
		811
		812	URxvt.keysym.C-M-q: command:\033[3;5;5t
		813	URxvt.keysym.C-M-y: command:\033[3;5;606t
		814	URxvt.keysym.C-M-e: command:\033[3;1605;5t
		815	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		816	URxvt.keysym.C-M-p: perl:test
		817
		818	The first for keysym definitions allow me to quickly bring some windows
		819	in the layout I like most. Ion users might start laughing but will stop
		820	immediately when I tell them that I use my own Fvwm2 module for much the
		821	same effect as Ion provides, and I only very rarely use the above key
		822	combinations :->
		823
		824	=head3 Why doesn't rxvt-unicode read my resources?
		825
		826	Well, why, indeed? It does, in a way very similar to other X
		827	applications. Most importantly, this means that if you or your OS loads
		828	resources into the X display (the right way to do it), rxvt-unicode will
		829	ignore any resource files in your home directory. It will only read
		830	F<$HOME/.Xdefaults> when no resources are attached to the display.
		831
		832	If you have or use an F<$HOME/.Xresources> file, chances are that
		833	resources are loaded into your X-server. In this case, you have to
		834	re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
		835
		836	Also consider the form resources have to use:
		837
		838	URxvt.resource: value
		839
		840	If you want to use another form (there are lots of different ways of
		841	specifying resources), make sure you understand whether and why it
		842	works. If unsure, use the form above.
		843
		844	=head3 When I log-in to another system it tells me about missing terminfo data?
		845
		846	The terminal description used by rxvt-unicode is not as widely available
		847	as that for xterm, or even rxvt (for which the same problem often arises).
		848
		849	The correct solution for this problem is to install the terminfo, this can
		850	be done like this (with ncurses' infocmp and works as user and admin):
		851
		852	REMOTE=remotesystem.domain
		853	infocmp rxvt-unicode \| ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
		854
		855	... or by installing rxvt-unicode normally on the remote system,
		856
		857	One some systems you might need to set C<$TERMINFO> to the full path of
		858	F<$HOME/.terminfo> for this to work.
		859
		860	If you cannot or do not want to do this, then you can simply set
		861	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		862	problems arising, which includes wrong keymapping, less and different
		863	colours and some refresh errors in fullscreen applications. It's a nice
		864	quick-and-dirty workaround for rare cases, though.
		865
		866	If you always want to do this (and are fine with the consequences) you
		867	can either recompile rxvt-unicode with the desired TERM value or use a
		868	resource to set it:
		869
		870	URxvt.termName: rxvt
		871
		872	If you don't plan to use B<rxvt> (quite common...) you could also replace
		873	the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
		874
		875	=head3 C<tic> outputs some error when compiling the terminfo entry.
		876
		877	Most likely it's the empty definition for C<enacs=>. Just replace it by
		878	C<enacs=\E[0@> and try again.
		879
		880	=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
		881
		882	See next entry.
		883
		884	=head3 I need a termcap file entry.
		885
		886	One reason you might want this is that some distributions or operating
		887	systems still compile some programs using the long-obsoleted termcap
		888	library (Fedora Core's bash is one example) and rely on a termcap entry
		889	for C<rxvt-unicode>.
		890
		891	You could use rxvt's termcap entry with reasonable results in many cases.
		892	You can also create a termcap entry by using terminfo's infocmp program
		893	like this:
		894
		895	infocmp -C rxvt-unicode
		896
		897	Or you could use this termcap entry, generated by the command above:
		898

		920	=head3 Why does C<ls> no longer have coloured output?
		921
		922	The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
		923	decide whether a terminal has colour, but uses its own configuration
		924	file. Needless to say, C<rxvt-unicode> is not in its default file (among
		925	with most other terminals supporting colour). Either add:
		926
		927	TERM rxvt-unicode
		928
		929	to C</etc/DIR_COLORS> or simply add:
		930
		931	alias ls='ls --color=auto'
		932
		933	to your C<.profile> or C<.bashrc>.
		934
		935	=head3 Why doesn't vim/emacs etc. use the 88 colour mode?
		936
		937	See next entry.
		938
		939	=head3 Why doesn't vim/emacs etc. make use of italic?
		940
		941	See next entry.
		942
		943	=head3 Why are the secondary screen-related options not working properly?
		944
		945	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		946	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		947	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		948	features. Unfortunately, some of these (most notably, again, Debian
		949	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		950	file, so you will need to install it on your own (See the question B<When
		951	I log-in to another system it tells me about missing terminfo data?> on
		952	how to do this).
		953
		954
		955	=head2 Encoding / Locale / Input Method Issues
		956
		957	=head3 Rxvt-unicode does not seem to understand the selected encoding?
		958
		959	See next entry.
		960
		961	=head3 Unicode does not seem to work?
		962
		963	If you encounter strange problems like typing an accented character but
		964	getting two unrelated other characters or similar, or if program output is
		965	subtly garbled, then you should check your locale settings.
		966
		967	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		968	programs running in it. Often rxvt-unicode is started in the C<C> locale,
		969	while the login script running within the rxvt-unicode window changes the
		970	locale to something else, e.g. C<en_GB.UTF-8>. Needless to say, this is
		971	not going to work, and is the most common cause for problems.
		972
		973	The best thing is to fix your startup environment, as you will likely run
		974	into other problems. If nothing works you can try this in your .profile.
		975
		976	printf '\33]701;%s\007' "$LC_CTYPE" # $LANG or $LC_ALL are worth a try, too
		977
		978	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		979	supported on your systems. Some systems have a C<locale> command which
		980	displays this (also, C<perl -e0> can be used to check locale settings, as
		981	it will complain loudly if it cannot set the locale). If it displays something
		982	like:
		983
		984	locale: Cannot set LC_CTYPE to default locale: ...
		985
		986	Then the locale you specified is not supported on your system.
		987
		988	If nothing works and you are sure that everything is set correctly then
		989	you will need to remember a little known fact: Some programs just don't
		990	support locales :(
		991
		992	=head3 How does rxvt-unicode determine the encoding to use?
		993
		994	See next entry.
		995
		996	=head3 Is there an option to switch encodings?
		997
		998	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		999	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		1000	UTF-8 or any other encodings with respect to terminal I/O.
		1001
		1002	The reasons is that there exists a perfectly fine mechanism for selecting
		1003	the encoding, doing I/O and (most important) communicating this to all
		1004	applications so everybody agrees on character properties such as width
		1005	and code number. This mechanism is the I<locale>. Applications not using
		1006	that info will have problems (for example, C<xterm> gets the width of
		1007	characters wrong as it uses its own, locale-independent table under all
		1008	locales).
		1009
		1010	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		1011	programs doing the same (that is, most) will automatically agree in the
		1012	interpretation of characters.
		1013
		1014	Unfortunately, there is no system-independent way to select locales, nor
		1015	is there a standard on how locale specifiers will look like.
		1016
		1017	On most systems, the content of the C<LC_CTYPE> environment variable
		1018	contains an arbitrary string which corresponds to an already-installed
		1019	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		1020	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		1021	(i.e. C<de> or C<german>) are also common.
		1022
		1023	Rxvt-unicode ignores all other locale categories, and except for
		1024	the encoding, ignores country or language-specific settings,
		1025	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		1026	rxvt-unicode.
		1027
		1028	If you want to use a specific encoding you have to make sure you start
		1029	rxvt-unicode with the correct C<LC_CTYPE> category.
		1030
		1031	=head3 Can I switch locales at runtime?
		1032
		1033	Yes, using an escape sequence. Try something like this, which sets
		1034	rxvt-unicode's idea of C<LC_CTYPE>.
		1035
		1036	printf '\33]701;%s\007' ja_JP.SJIS
		1037
		1038	See also the previous answer.
		1039
		1040	Sometimes this capability is rather handy when you want to work in
		1041	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		1042	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		1043	first switches to a locale supported by xjdic and back later:
		1044
		1045	printf '\33]701;%s\007' ja_JP.SJIS
		1046	xjdic -js
		1047	printf '\33]701;%s\007' de_DE.UTF-8
		1048
		1049	You can also use xterm's C<luit> program, which usually works fine, except
		1050	for some locales where character width differs between program- and
		1051	rxvt-unicode-locales.
		1052
		1053	=head3 I have problems getting my input method working.
		1054
		1055	Try a search engine, as this is slightly different for every input method server.
		1056
		1057	Here is a checklist:
		1058
		1059	=over 4
		1060
		1061	=item - Make sure your locale I<and> the imLocale are supported on your OS.
		1062
		1063	Try C<locale -a> or check the documentation for your OS.
		1064
		1065	=item - Make sure your locale or imLocale matches a locale supported by your XIM.
		1066
		1067	For example, B<kinput2> does not support UTF-8 locales, you should use
		1068	C<ja_JP.EUC-JP> or equivalent.
		1069
		1070	=item - Make sure your XIM server is actually running.
		1071
		1072	=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
		1073
		1074	When you want to use e.g. B<kinput2>, it must be set to
		1075	C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
		1076	method servers are running with this command:
		1077
		1078	xprop -root XIM_SERVERS
		1079
		1080	=item
599		1081
600	=back	1082	=back
601		1083
602	=head1 SYNOPSIS	1084	=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
603		1085
604	# set a new font set	1086	You can specify separate locales for the input method and the rest of the
605	printf '\33]50;%s\007' 9x15,xft:Kochi" Mincho"	1087	terminal, using the resource C<imlocale>:
606		1088
607	# change the locale and tell rxvt-unicode about it	1089	URxvt.imlocale: ja_JP.EUC-JP
608	export LC_CTYPE=ja_JP.EUC-JP; printf "\33]701;$LC_CTYPE\007"
609		1090
610	# set window title	1091	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
611	printf '\33]2;%s\007' "new window title"	1092	use your input method. Please note, however, that, depending on your Xlib
		1093	version, you may not be able to input characters outside C<EUC-JP> in a
		1094	normal way then, as your input method limits you.
612		1095
613	=head1 DESCRIPTION	1096	=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
		1097
		1098	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		1099	design. Applications can avoid some crashes at the expense of memory
		1100	leaks, and Input Methods can avoid some crashes by careful ordering at
		1101	exit time. B<kinput2> (and derived input methods) generally succeeds,
		1102	while B<SCIM> (or similar input methods) fails. In the end, however,
		1103	crashes cannot be completely avoided even if both sides cooperate.
		1104
		1105	So the only workaround is not to kill your Input Method Servers.
		1106
		1107
		1108	=head2 Operating Systems / Package Maintaining
		1109
		1110	=head3 I am using Debian GNU/Linux and have a problem...
		1111
		1112	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		1113	patches that considerably change the behaviour of rxvt-unicode (but
		1114	unfortunately this notice has been removed). Before reporting a bug to
		1115	the original rxvt-unicode author please download and install the genuine
		1116	version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
		1117	the problem. If you cannot, chances are that the problems are specific to
		1118	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		1119	Tracking System (use C<reportbug> to report the bug).
		1120
		1121	For other problems that also affect the Debian package, you can and
		1122	probably should use the Debian BTS, too, because, after all, it's also a
		1123	bug in the Debian version and it serves as a reminder for other users that
		1124	might encounter the same issue.
		1125
		1126	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		1127
		1128	You should build one binary with the default options. F<configure>
		1129	now enables most useful options, and the trend goes to making them
		1130	runtime-switchable, too, so there is usually no drawback to enabling them,
		1131	except higher disk and possibly memory usage. The perl interpreter should
		1132	be enabled, as important functionality (menus, selection, likely more in
		1133	the future) depends on it.
		1134
		1135	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		1136	system-wide (except maybe with C<defaults>). This will result in useful
		1137	behaviour. If your distribution aims at low memory, add an empty
		1138	C<perl-ext-common> resource to the app-defaults file. This will keep the
		1139	perl interpreter disabled until the user enables it.
		1140
		1141	If you can/want build more binaries, I recommend building a minimal
		1142	one with C<--disable-everything> (very useful) and a maximal one with
		1143	C<--enable-everything> (less useful, it will be very big due to a lot of
		1144	encodings built-in that increase download times and are rarely used).
		1145
		1146	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		1147
		1148	It should be, starting with release 7.1. You are encouraged to properly
		1149	install urxvt with privileges necessary for your OS now.
		1150
		1151	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		1152	into a helper process for privileged operations (pty handling on some
		1153	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		1154	immediately. This is much safer than most other terminals that keep
		1155	privileges while running (but is more relevant to urxvt, as it contains
		1156	things as perl interpreters, which might be "helpful" to attackers).
		1157
		1158	This forking is done as the very first within main(), which is very early
		1159	and reduces possible bugs to initialisation code run before main(), or
		1160	things like the dynamic loader of your system, which should result in very
		1161	little risk.
		1162
		1163	=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
		1164
		1165	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
		1166	in your compile environment, or an implementation that implements it,
		1167	whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
		1168	B<wchar_t> is represented as unicode.
		1169
		1170	As you might have guessed, FreeBSD does neither define this symbol nor
		1171	does it support it. Instead, it uses its own internal representation of
		1172	B<wchar_t>. This is, of course, completely fine with respect to standards.
		1173
		1174	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		1175	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
		1176
		1177	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		1178	apps in an OS, as using a locale-dependent (and non-standardized)
		1179	representation of B<wchar_t> makes it impossible to convert between
		1180	B<wchar_t> (as used by X11 and your applications) and any other encoding
		1181	without implementing OS-specific-wrappers for each and every locale. There
		1182	simply are no APIs to convert B<wchar_t> into anything except the current
		1183	locale encoding.
		1184
		1185	Some applications (such as the formidable B<mlterm>) work around this
		1186	by carrying their own replacement functions for character set handling
		1187	with them, and either implementing OS-dependent hacks or doing multiple
		1188	conversions (which is slow and unreliable in case the OS implements
		1189	encodings slightly different than the terminal emulator).
		1190
		1191	The rxvt-unicode author insists that the right way to fix this is in the
		1192	system libraries once and for all, instead of forcing every app to carry
		1193	complete replacements for them :)
		1194
		1195	=head3 How can I use rxvt-unicode under cygwin?
		1196
		1197	rxvt-unicode should compile and run out of the box on cygwin, using
		1198	the X11 libraries that come with cygwin. libW11 emulation is no
		1199	longer supported (and makes no sense, either, as it only supported a
		1200	single font). I recommend starting the X-server in C<-multiwindow> or
		1201	C<-rootless> mode instead, which will result in similar look&feel as the
		1202	old libW11 emulation.

		1204	At the time of this writing, cygwin didn't seem to support any multi-byte
		1205	encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
		1206	to 8-bit encodings.

		1208	=head3 Character widths are not correct.
		1209
		1210	urxvt uses the system wcwidth function to know the information about
		1211	the width of characters, so on systems with incorrect locale data you
		1212	will likely get bad results. Two notorious examples are Solaris 9,
		1213	where single-width characters like U+2514 are reported as double-width,
		1214	and Darwin 8, where combining chars are reported having width 1.
		1215
		1216	The solution is to upgrade your system or switch to a better one. A
		1217	possibly working workaround is to use a wcwidth implementation like

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

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]>

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!.
