29=item The new selection selects pieces that are too big, how can I select 30=head2 Meta, Features & Commandline Issues
30single words?
31 31
32Yes. For example, if you want to select alphanumeric words, you can use 32=head3 My question isn't answered here, can I ask a human?
33the following resource:

35 URxvt.selection.pattern-0: ([[:word:]]+) 34Before sending me mail, you could go to IRC: C<irc.freenode.net>,
35channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
36interested in learning about new and exciting problems (but not FAQs :).
36 37
37If you click more than twice, the selection will be extended 38=head3 I use Gentoo, and I have a problem...
38more and more.
39 39
40To get a selection that is very similar to the old code, try this pattern: 40There are two big problems with Gentoo Linux: first, most if not all
41Gentoo systems are completely broken (missing or mismatched header
42files, broken compiler etc. are just the tip of the iceberg);
43secondly, it should be called Gentoo GNU/Linux.
41 44
42 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+) 45For these reasons, it is impossible to support rxvt-unicode on
46Gentoo. Problems appearing on Gentoo systems will usually simply be
47ignored unless they can be reproduced on non-Gentoo systems.
43 48
44Please also note that the I<LeftClick Shift-LeftClik> combination also 49=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
45selects words like the old code.
46 50
47=item I don't like the new selection/popups/hotkeys/perl, how do I 51Beginning with version 7.3, there is a perl extension that implements a
48change/disable it? 52simple tabbed terminal. It is installed by default, so any of these should
53give you tabs:
49 54
50You can disable the perl extension completely by setting the 55 @@URXVT_NAME@@ -pe tabbed
51B<perl-ext-common> resource to the empty string, which also keeps
52rxvt-unicode from initialising perl, saving memory.
53 56
54If you only want to disable specific features, you first have to 57 URxvt.perl-ext-common: default,tabbed
55identify which perl extension is responsible. For this, read the section
56B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
57example, to disable the B<selection-popup> and B<option-popup>, specify
58this B<perl-ext-common> resource:
59 58
60 URxvt.perl-ext-common: default,-selection-popup,-option-popup 59It will also work fine with tabbing functionality of many window managers
60or similar tabbing programs, and its embedding-features allow it to be
61embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
62the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
63(murxvt) terminal as an example embedding application.
61 64
62This will keep the default extensions, but disable the two popup 65=head3 How do I know which rxvt-unicode version I'm using?
63extensions. Some extensions can also be configured, for example,
64scrollback search mode is triggered by B<M-s>. You can move it to any
65other combination either by setting the B<searchable-scrollback> resource:
66 66
67 URxvt.searchable-scrollback: CM-s 67The version number is displayed with the usage (-h). Also the escape
68sequence C<ESC [ 8 n> sets the window title to the version number. When
69using the @@URXVT_NAME@@c client, the version displayed is that of the
70daemon.
68 71
72=head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
73
74Rxvt-unicode tries to obey the rule of not charging you for something you
75don't use. One thing you should try is to configure out all settings that
76you don't need, for example, Xft support is a resource hog by design,
77when used. Compiling it out ensures that no Xft font will be loaded
78accidentally when rxvt-unicode tries to find a font for your characters.
79
80Also, many people (me included) like large windows and even larger
81scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
826 bytes per screen cell. For a 160x?? window this amounts to almost a
83kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
84use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
85rxvt-unicode then uses 8 bytes per screen cell.
86
87=head3 How can I start @@URXVT_NAME@@d in a race-free way?
88
89Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
90display, create the listening socket and then fork.
91
92=head3 How can I start @@URXVT_NAME@@d automatically when I run @@URXVT_NAME@@c?
93
94If you want to start @@URXVT_NAME@@d automatically whenever you run
95@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
96
97 #!/bin/sh
98 @@URXVT_NAME@@c "$@"
99 if [ $? -eq 2 ]; then
100 @@URXVT_NAME@@d -q -o -f
101 @@URXVT_NAME@@c "$@"
102 fi
103
104This tries to create a new terminal, and if fails with exit status 2,
105meaning it couldn't connect to the daemon, it will start the daemon and
106re-run the command. Subsequent invocations of the script will re-use the
107existing daemon.
108
109=head3 How do I distinguish whether I'm running rxvt-unicode or a regular
110xterm? I need this to decide about setting colours etc.
111
112The original rxvt and rxvt-unicode always export the variable "COLORTERM",
113so you can check and see if that is set. Note that several programs, JED,
114slrn, Midnight Commander automatically check this variable to decide
115whether or not to use colour.
116
117=head3 How do I set the correct, full IP address for the DISPLAY variable?
118
119If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
120insecure mode then it is possible to use the following shell script
121snippets to correctly set the display. If your version of rxvt-unicode
122wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
123the COLORTERM variable can be used to distinguish rxvt-unicode from a
124regular xterm.
125
126Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
127snippets:
128

141
142=head3 How do I compile the manual pages on my own?
143
144You need to have a recent version of perl installed as F</usr/bin/perl>,
145one that comes with F<pod2man>, F<pod2text> and F<pod2xhtml> (from
146F<Pod::Xhtml>). Then go to the doc subdirectory and enter C<make alldoc>.

145=item Does it support tabs, can I have a tabbed rxvt-unicode?
146 224
147rxvt-unicode does not directly support tabs. It will work fine with 225=head2 Rendering, Font & Look and Feel Issues
148tabbing functionality of many window managers or similar tabbing programs,
149and its embedding-features allow it to be embedded into other programs,
150as witnessed by F<doc/rxvt-tabbed> or the upcoming C<Gtk2::URxvt> perl
151module, which features a tabbed urxvt (murxvt) terminal as an example
152embedding application.
153 226
154=item How do I know which rxvt-unicode version I'm using? 227=head3 I can't get transparency working, what am I doing wrong?
155 228
156The version number is displayed with the usage (-h). Also the escape 229First of all, transparency isn't officially supported in rxvt-unicode, so
157sequence C<ESC [ 8 n> sets the window title to the version number. When 230you are mostly on your own. Do not bug the author about it (but you may

159daemon. 232of passage: ... and you failed.
160 233
161=item I am using Debian GNU/Linux and have a problem... 234Here are four ways to get transparency. B<Do> read the manpage and option
235descriptions for the programs mentioned and rxvt-unicode. Really, do it!
162 236
163The Debian GNU/Linux package of rxvt-unicode in sarge contains large 2371. Use transparent mode:
164patches that considerably change the behaviour of rxvt-unicode (but
165unfortunately this notice has been removed). Before reporting a bug to
166the original rxvt-unicode author please download and install the genuine
167version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
168the problem. If you cannot, chances are that the problems are specific to
169Debian GNU/Linux, in which case it should be reported via the Debian Bug
170Tracking System (use C<reportbug> to report the bug).
171 238
172For other problems that also affect the Debian package, you can and 239 Esetroot wallpaper.jpg
173probably should use the Debian BTS, too, because, after all, it's also a 240 @@URXVT_NAME@@ -tr -tint red -sh 40
174bug in the Debian version and it serves as a reminder for other users that
175might encounter the same issue.

177=item I am maintaining rxvt-unicode for distribution/OS XXX, any 242That works. If you think it doesn't, you lack transparency and tinting
178recommendation? 243support, or you are unable to read.
244This method requires that the background-setting program sets the
245_XROOTPMAP_ID or ESETROOT_PMAP_ID property. Compatible programs
246are Esetroot, hsetroot and feh.
179 247
180You should build one binary with the default options. F<configure> 2482. Use a simple pixmap and emulate pseudo-transparency. This enables you
181now enables most useful options, and the trend goes to making them 249to use effects other than tinting and shading: Just shade/tint/whatever
182runtime-switchable, too, so there is usually no drawback to enbaling them, 250your picture with gimp or any other tool:
183except higher disk and possibly memory usage. The perl interpreter should
184be enabled, as important functionality (menus, selection, likely more in
185the future) depends on it.
186 251
187You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources 252 convert wallpaper.jpg -blur 20x20 -modulate 30 background.jpg
188system-wide (except maybe with C<defaults>). This will result in useful 253 @@URXVT_NAME@@ -pixmap "background.jpg;:root"
189behaviour. If your distribution aims at low memory, add an empty
190C<perl-ext-common> resource to the app-defaults file. This will keep the
191perl interpreter disabled until the user enables it.
192 254
193If you can/want build more binaries, I recommend building a minimal 255That works. If you think it doesn't, you lack GDK-PixBuf support, or you
194one with C<--disable-everything> (very useful) and a maximal one with 256are unable to read.
195C<--enable-everything> (less useful, it will be very big due to a lot of
196encodings built-in that increase download times and are rarely used).
197 257
198=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe? 2583. Use an ARGB visual:
199 259
200It should be, starting with release 7.1. You are encouraged to properly 260 @@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
201install urxvt with privileges necessary for your OS now.
202 261
203When rxvt-unicode detects that it runs setuid or setgid, it will fork 262This requires XFT support, and the support of your X-server. If that
204into a helper process for privileged operations (pty handling on some 263doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
205systems, utmp/wtmp/lastlog handling on others) and drop privileges 264there yet, no matter what they claim. Rxvt-Unicode contains the necessary

208things as perl interpreters, which might be "helpful" to attackers).
209 267
210This forking is done as the very first within main(), which is very early 2684. Use xcompmgr and let it do the job:
211and reduces possible bugs to initialisation code run before main(), or
212things like the dynamic loader of your system, which should result in very
213little risk.
214 269
215=item When I log-in to another system it tells me about missing terminfo data? 270 xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
271 -set _NET_WM_WINDOW_OPACITY 0xc0000000
216 272
217The terminal description used by rxvt-unicode is not as widely available 273Then click on a window you want to make transparent. Replace C<0xc0000000>
218as that for xterm, or even rxvt (for which the same problem often arises). 274by other values to change the degree of opacity. If it doesn't work and
275your server crashes, you got to keep the pieces.
219 276
220The correct solution for this problem is to install the terminfo, this can
221be done like this (with ncurses' infocmp):
222
223 REMOTE=remotesystem.domain
224 infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
225
226... or by installing rxvt-unicode normally on the remote system,
227
228If you cannot or do not want to do this, then you can simply set
229C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
230problems arising, which includes wrong keymapping, less and different
231colours and some refresh errors in fullscreen applications. It's a nice
232quick-and-dirty workaround for rare cases, though.
233
234If you always want to do this (and are fine with the consequences) you
235can either recompile rxvt-unicode with the desired TERM value or use a
236resource to set it:
237
238 URxvt.termName: rxvt
239
240If you don't plan to use B<rxvt> (quite common...) you could also replace
241the rxvt terminfo file with the rxvt-unicode one.
242
243=item C<tic> outputs some error when compiling the terminfo entry.
244
245Most likely it's the empty definition for C<enacs=>. Just replace it by
246C<enacs=\E[0@> and try again.
247
248=item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
249
250=item I need a termcap file entry.
251
252One reason you might want this is that some distributions or operating
253systems still compile some programs using the long-obsoleted termcap
254library (Fedora Core's bash is one example) and rely on a termcap entry
255for C<rxvt-unicode>.
256
257You could use rxvt's termcap entry with resonable results in many cases.
258You can also create a termcap entry by using terminfo's infocmp program
259like this:
260
261 infocmp -C rxvt-unicode
262
263Or you could use this termcap entry, generated by the command above:

286=item Why does C<ls> no longer have coloured output?
287
288The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
289decide wether a terminal has colour, but uses it's own configuration

291with most other terminals supporting colour). Either add:
292

304
305=item Why are the secondary screen-related options not working properly?
306
307Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
308distributions (most notably Debian GNU/Linux) break rxvt-unicode
309by setting C<TERM> to C<rxvt>, which doesn't have these extra
310features. Unfortunately, some of these (most notably, again, Debian
311GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
312file, so you will need to install it on your own (See the question B<When
313I log-in to another system it tells me about missing terminfo data?> on
314how to do this).
315
316=item My numerical keypad acts weird and generates differing output?
317
318Some Debian GNUL/Linux users seem to have this problem, although no
319specific details were reported so far. It is possible that this is caused
320by the wrong C<TERM> setting, although the details of wether and how
321this can happen are unknown, as C<TERM=rxvt> should offer a compatible
322keymap. See the answer to the previous question, and please report if that
323helped.
324
325=item Rxvt-unicode does not seem to understand the selected encoding?
326
327=item Unicode does not seem to work?
328
329If you encounter strange problems like typing an accented character but
330getting two unrelated other characters or similar, or if program output is
331subtly garbled, then you should check your locale settings.
332
333Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
334programs. Often rxvt-unicode is started in the C<C> locale, while the
335login script running within the rxvt-unicode window changes the locale to
336something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
337
338The best thing is to fix your startup environment, as you will likely run
339into other problems. If nothing works you can try this in your .profile.
340
341 printf '\e]701;%s\007' "$LC_CTYPE"
342
343If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
344supported on your systems. Some systems have a C<locale> command which
345displays this (also, C<perl -e0> can be used to check locale settings, as
346it will complain loudly if it cannot set the locale). If it displays something
347like:
348
349 locale: Cannot set LC_CTYPE to default locale: ...
350
351Then the locale you specified is not supported on your system.
352
353If nothing works and you are sure that everything is set correctly then
354you will need to remember a little known fact: Some programs just don't
355support locales :(
356
357=item Why do some characters look so much different than others?
358
359=item How does rxvt-unicode choose fonts?
360
361Most fonts do not contain the full range of Unicode, which is
362fine. Chances are that the font you (or the admin/package maintainer of
363your system/os) have specified does not cover all the characters you want
364to display.
365
366B<rxvt-unicode> makes a best-effort try at finding a replacement
367font. Often the result is fine, but sometimes the chosen font looks
368bad/ugly/wrong. Some fonts have totally strange characters that don't
369resemble the correct glyph at all, and rxvt-unicode lacks the artificial
370intelligence to detect that a specific glyph is wrong: it has to believe
371the font that the characters it claims to contain indeed look correct.
372
373In that case, select a font of your taste and add it to the font list,
374e.g.:
375
376 @@RXVT_NAME@@ -fn basefont,font2,font3...
377
378When rxvt-unicode sees a character, it will first look at the base
379font. If the base font does not contain the character, it will go to the
380next font, and so on. Specifying your own fonts will also speed up this
381search and use less resources within rxvt-unicode and the X-server.
382
383The only limitation is that none of the fonts may be larger than the base
384font, as the base font defines the terminal character cell size, which
385must be the same due to the way terminals work.
386
387=item Why do some chinese characters look so different than others?
388
389This is because there is a difference between script and language --
390rxvt-unicode does not know which language the text that is output is,
391as it only knows the unicode character codes. If rxvt-unicode first
392sees a japanese/chinese character, it might choose a japanese font for
393display. Subsequent japanese characters will use that font. Now, many
394chinese characters aren't represented in japanese fonts, so when the first
395non-japanese character comes up, rxvt-unicode will look for a chinese font
396-- unfortunately at this point, it will still use the japanese font for
397chinese characters that are also in the japanese font.
398
399The workaround is easy: just tag a chinese font at the end of your font
400list (see the previous question). The key is to view the font list as
401a preference list: If you expect more japanese, list a japanese font
402first. If you expect more chinese, put a chinese font first.
403
404In the future it might be possible to switch language preferences at
405runtime (the internal data structure has no problem with using different
406fonts for the same character at the same time, but no interface for this
407has been designed yet).
408
409Until then, you might get away with switching fonts at runtime (see L<Can
410I switch the fonts at runtime?> later in this document).

442=item My Compose (Multi_key) key is no longer working.
443
444The most common causes for this are that either your locale is not set

446your input method. For example, if you specified B<OverTheSpot> and
447your input method (e.g. the default input method handling Compose keys)
448does not support this (for instance because it is not visual), then
449rxvt-unicode will continue without an input method.
450
451In this case either do not specify a B<preeditStyle> or specify more than

482 319
483=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
484
485Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
486in your compile environment, or an implementation that implements it,
487wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
488B<wchar_t> is represented as unicode.
489
490As you might have guessed, FreeBSD does neither define this symobl nor
491does it support it. Instead, it uses it's own internal representation of
492B<wchar_t>. This is, of course, completely fine with respect to standards.
493
494However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
495C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
496
497C<__STDC_ISO_10646__> is the only sane way to support multi-language
498apps in an OS, as using a locale-dependent (and non-standardized)
499representation of B<wchar_t> makes it impossible to convert between
500B<wchar_t> (as used by X11 and your applications) and any other encoding
501without implementing OS-specific-wrappers for each and every locale. There
502simply are no APIs to convert B<wchar_t> into anything except the current
503locale encoding.
504
505Some applications (such as the formidable B<mlterm>) work around this
506by carrying their own replacement functions for character set handling
507with them, and either implementing OS-dependent hacks or doing multiple
508conversions (which is slow and unreliable in case the OS implements
509encodings slightly different than the terminal emulator).
510
511The rxvt-unicode author insists that the right way to fix this is in the
512system libraries once and for all, instead of forcing every app to carry
513complete replacements for them :)
514

518problems with C<wcwidth> and a compile problem.
519
520=item How can I use rxvt-unicode under cygwin?
521
522rxvt-unicode should compile and run out of the box on cygwin, using
523the X11 libraries that come with cygwin. libW11 emulation is no
524longer supported (and makes no sense, either, as it only supported a
525single font). I recommend starting the X-server in C<-multiwindow> or
526C<-rootless> mode instead, which will result in similar look&feel as the
527old libW11 emulation.
528
529At the time of this writing, cygwin didn't seem to support any multi-byte
530encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
531to 8-bit encodings.
532
533=item How does rxvt-unicode determine the encoding to use?
534
535=item Is there an option to switch encodings?
536
537Unlike some other terminals, rxvt-unicode has no encoding switch, and no
538specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
539UTF-8 or any other encodings with respect to terminal I/O.
540
541The reasons is that there exists a perfectly fine mechanism for selecting
542the encoding, doing I/O and (most important) communicating this to all
543applications so everybody agrees on character properties such as width
544and code number. This mechanism is the I<locale>. Applications not using
545that info will have problems (for example, C<xterm> gets the width of
546characters wrong as it uses it's own, locale-independent table under all
547locales).
548
549Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
550programs doing the same (that is, most) will automatically agree in the
551interpretation of characters.
552
553Unfortunately, there is no system-independent way to select locales, nor
554is there a standard on how locale specifiers will look like.
555
556On most systems, the content of the C<LC_CTYPE> environment variable
557contains an arbitrary string which corresponds to an already-installed
558locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
559C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
560(i.e. C<de> or C<german>) are also common.
561
562Rxvt-unicode ignores all other locale categories, and except for
563the encoding, ignores country or language-specific settings,
564i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
565rxvt-unicode.
566
567If you want to use a specific encoding you have to make sure you start
568rxvt-unicode with the correct C<LC_CTYPE> category.
569
570=item Can I switch locales at runtime?
571
572Yes, using an escape sequence. Try something like this, which sets
573rxvt-unicode's idea of C<LC_CTYPE>.
574
575 printf '\e]701;%s\007' ja_JP.SJIS
576
577See also the previous answer.
578
579Sometimes this capability is rather handy when you want to work in
580one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
581(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
582first switches to a locale supported by xjdic and back later:
583
584 printf '\e]701;%s\007' ja_JP.SJIS
585 xjdic -js
586 printf '\e]701;%s\007' de_DE.UTF-8
587
588You can also use xterm's C<luit> program, which usually works fine, except
589for some locales where character width differs between program- and
590rxvt-unicode-locales.
591
592=item Can I switch the fonts at runtime? 320=head3 Can I switch the fonts at runtime?

594Yes, using an escape sequence. Try something like this, which has the same 322Yes, using an escape sequence. Try something like this, which has the same

615=item My input method wants <some encoding> but I want UTF-8, what can I do?

617You can specify separate locales for the input method and the rest of the
618terminal, using the resource C<imlocale>:
619
620 URxvt.imlocale: ja_JP.EUC-JP
621
622Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
623use your input method. Please note, however, that you will not be able to
624input characters outside C<EUC-JP> in a normal way then, as your input
625method limits you.
626
627=item Rxvt-unicode crashes when the X Input Method changes or exits.
628
629Unfortunately, this is unavoidable, as the XIM protocol is racy by
630design. Applications can avoid some crashes at the expense of memory
631leaks, and Input Methods can avoid some crashes by careful ordering at
632exit time. B<kinput2> (and derived input methods) generally succeeds,
633while B<SCIM> (or similar input methods) fails. In the end, however,
634crashes cannot be completely avoided even if both sides cooperate.
635
636So the only workaround is not to kill your Input Method Servers.
637
638=item Rxvt-unicode uses gobs of memory, how can I reduce that?
639
640Rxvt-unicode tries to obey the rule of not charging you for something you
641don't use. One thing you should try is to configure out all settings that
642you don't need, for example, Xft support is a resource hog by design,
643when used. Compiling it out ensures that no Xft font will be loaded
644accidentally when rxvt-unicode tries to find a font for your characters.
645
646Also, many people (me included) like large windows and even larger
647scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
6486 bytes per screen cell. For a 160x?? window this amounts to almost a
649kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
650use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
651rxvt-unicode then uses 8 bytes per screen cell.

429=head3 How does rxvt-unicode choose fonts?
430
431Most fonts do not contain the full range of Unicode, which is
432fine. Chances are that the font you (or the admin/package maintainer of
433your system/os) have specified does not cover all the characters you want
434to display.
435
436B<rxvt-unicode> makes a best-effort try at finding a replacement
437font. Often the result is fine, but sometimes the chosen font looks
438bad/ugly/wrong. Some fonts have totally strange characters that don't
439resemble the correct glyph at all, and rxvt-unicode lacks the artificial
440intelligence to detect that a specific glyph is wrong: it has to believe
441the font that the characters it claims to contain indeed look correct.
442
443In that case, select a font of your taste and add it to the font list,
444e.g.:
445
446 @@URXVT_NAME@@ -fn basefont,font2,font3...
447
448When rxvt-unicode sees a character, it will first look at the base
449font. If the base font does not contain the character, it will go to the
450next font, and so on. Specifying your own fonts will also speed up this
451search and use less resources within rxvt-unicode and the X-server.
452
453The only limitation is that none of the fonts may be larger than the base
454font, as the base font defines the terminal character cell size, which
455must be the same due to the way terminals work.
456
457=head3 Why do some chinese characters look so different than others?
458
459This is because there is a difference between script and language --
460rxvt-unicode does not know which language the text that is output is,
461as it only knows the unicode character codes. If rxvt-unicode first
462sees a japanese/chinese character, it might choose a japanese font for
463display. Subsequent japanese characters will use that font. Now, many
464chinese characters aren't represented in japanese fonts, so when the first
465non-japanese character comes up, rxvt-unicode will look for a chinese font
466-- unfortunately at this point, it will still use the japanese font for
467chinese characters that are also in the japanese font.
468
469The workaround is easy: just tag a chinese font at the end of your font
470list (see the previous question). The key is to view the font list as
471a preference list: If you expect more japanese, list a japanese font
472first. If you expect more chinese, put a chinese font first.
473
474In the future it might be possible to switch language preferences at
475runtime (the internal data structure has no problem with using different
476fonts for the same character at the same time, but no interface for this
477has been designed yet).
478
479Until then, you might get away with switching fonts at runtime (see L<Can
480I switch the fonts at runtime?> later in this document).

488=head3 Why is the cursor now blinking in emacs/vi/...?
489
490This is likely caused by your editor/program's use of the C<cvvis>
491terminfo capability. Emacs uses it by default, as well as some versions of
492vi and possibly other programs.
493
494In emacs, you can switch that off by adding this to your C<.emacs> file:
495
496 (setq visible-cursor nil)
497
498For other programs, if they do not have an option, your have to remove the
499C<cvvis> capability from the terminfo description.
500
501When @@URXVT_NAME@@ first added the blinking cursor option, it didn't
502add a C<cvvis> capability, which served no purpose before. Version 9.21
503introduced C<cvvis> (and the ability to control blinking independent of
504cursor shape) for compatibility with other terminals, which traditionally
505use a blinking cursor for C<cvvis>. This also reflects the intent of
506programs such as emacs, who expect C<cvvis> to enable a blinking cursor.

510=head3 The new selection selects pieces that are too big, how can I select single words?
511
512If you want to select e.g. alphanumeric words, you can use the following
513setting:
514
515 URxvt.selection.pattern-0: ([[:word:]]+)
516
517If you click more than twice, the selection will be extended
518more and more.
519
520To get a selection that is very similar to the old code, try this pattern:
521
522 URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
523
524Please also note that the I<LeftClick Shift-LeftClick> combination also
525selects words like the old code.
526
527=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
528
529You can disable the perl extension completely by setting the
530B<perl-ext-common> resource to the empty string, which also keeps
531rxvt-unicode from initialising perl, saving memory.
532
533If you only want to disable specific features, you first have to
534identify which perl extension is responsible. For this, read the section
535B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
536example, to disable the B<selection-popup> and B<option-popup>, specify
537this B<perl-ext-common> resource:
538
539 URxvt.perl-ext-common: default,-selection-popup,-option-popup
540
541This will keep the default extensions, but disable the two popup
542extensions. Some extensions can also be configured, for example,
543scrollback search mode is triggered by B<M-s>. You can move it to any
544other combination by adding a B<keysym> resource that binds the desired
545combination to the C<start> action of C<searchable-scrollback> and another
546one that binds B<M-s> to the C<builtin:> action:

554
555=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
556
557These are caused by the C<readline> perl extension. Under normal
558circumstances, it will move your cursor around when you click into the
559line that contains it. It tries hard not to do this at the wrong moment,
560but when running a program that doesn't parse cursor movements or in some
561cases during rlogin sessions, it fails to detect this properly.
562
563You can permanently switch this feature off by disabling the C<readline>
564extension:

568=head3 My numeric keypad acts weird and generates differing output?
569
570Some Debian GNU/Linux users seem to have this problem, although no
571specific details were reported so far. It is possible that this is caused
572by the wrong C<TERM> setting, although the details of whether and how
573this can happen are unknown, as C<TERM=rxvt> should offer a compatible
574keymap. See the answer to the previous question, and please report if that
575helped.
576
577=head3 My Compose (Multi_key) key is no longer working.
578
579The most common causes for this are that either your locale is not set
580correctly, or you specified a B<preeditType> that is not supported by
581your input method. For example, if you specified B<OverTheSpot> and
582your input method (e.g. the default input method handling Compose keys)
583does not support this (for instance because it is not visual), then
584rxvt-unicode will continue without an input method.
585
586In this case either do not specify a B<preeditType> or specify more than
587one pre-edit style, such as B<OverTheSpot,Root,None>.
588
589If it still doesn't work, then maybe your input method doesn't support
590compose sequences - to fall back to the built-in one, make sure you don't
591specify an input method via C<-im> or C<XMODIFIERS>.

595Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
596international keyboards) or simply use ISO 14755 support to your
597advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
598codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
599character and so on.

713This is my perl configuration. The first two set the perl library
714directory and also tells urxvt to use a large number of extensions. I
715develop for myself mostly, so I actually use most of the extensions I
716write.
717
718The selection stuff mainly makes the selection perl-error-message aware
719and tells it to convert perl error messages into vi-commands to load the
720relevant file and go to the error line number.
721
722 URxvt.scrollstyle: plain
723 URxvt.secondaryScroll: true
724
725As the documentation says: plain is the preferred scrollbar for the
726author. The C<secondaryScroll> configures urxvt to scroll in full-screen
727apps, like screen, so lines scrolled out of screen end up in urxvt's
728scrollback buffer.
729
730 URxvt.background: #000000
731 URxvt.foreground: gray90
732 URxvt.color7: gray90
733 URxvt.colorBD: #ffffff
734 URxvt.cursorColor: #e0e080
735 URxvt.throughColor: #8080f0
736 URxvt.highlightColor: #f0f0f0
737
738Some colours. Not sure which ones are being used or even non-defaults, but
739these are in my .Xdefaults. Most notably, they set foreground/background
740to light gray/black, and also make sure that the colour 7 matches the
741default foreground colour.
742
743 URxvt.underlineColor: yellow
744
745Another colour, makes underline lines look different. Sometimes hurts, but
746is mostly a nice effect.
747
748 URxvt.geometry: 154x36
749 URxvt.loginShell: false
750 URxvt.meta: ignore
751 URxvt.utmpInhibit: true
752
753Uh, well, should be mostly self-explanatory. By specifying some defaults
754manually, I can quickly switch them for testing.
755
756 URxvt.saveLines: 8192
757
758A large scrollback buffer is essential. Really.
759
760 URxvt.mapAlert: true
761
762The only case I use it is for my IRC window, which I like to keep
763iconified till people msg me (which beeps).
764
765 URxvt.visualBell: true
766
767The audible bell is often annoying, especially when in a crowd.
768
769 URxvt.insecure: true
770
771Please don't hack my mutt! Ooops...
772
773 URxvt.pastableTabs: false
774
775I once thought this is a great idea.
776
777 urxvt.font: 9x15bold,\
778 -misc-fixed-bold-r-normal--15-140-75-75-c-90-iso10646-1,\
779 -misc-fixed-medium-r-normal--15-140-75-75-c-90-iso10646-1, \
780 [codeset=JISX0208]xft:Kochi Gothic, \
781 xft:Bitstream Vera Sans Mono:autohint=true, \
782 xft:Code2000:antialias=false
783 urxvt.boldFont: -xos4-terminus-bold-r-normal--14-140-72-72-c-80-iso8859-15
784 urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
785 urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
786
787I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
788overwhelmed. A special note: the C<9x15bold> mentioned above is actually
789the version from XFree-3.3, as XFree-4 replaced it by a totally different
790font (different glyphs for C<;> and many other harmless characters),
791while the second font is actually the C<9x15bold> from XFree4/XOrg. The
792bold version has less chars than the medium version, so I use it for rare
793characters, too. When editing sources with vim, I use italic for comments
794and other stuff, which looks quite good with Bitstream Vera anti-aliased.
795
796Terminus is a quite bad font (many very wrong glyphs), but for most of my
797purposes, it works, and gives a different look, as my normal (Non-bold)
798font is already bold, and I want to see a difference between bold and
799normal fonts.
800
801Please note that I used the C<urxvt> instance name and not the C<URxvt>
802class name. That is because I use different configs for different purposes,
803for example, my IRC window is started with C<-name IRC>, and uses these
804defaults:
805
806 IRC*title: IRC
807 IRC*geometry: 87x12+535+542
808 IRC*saveLines: 0
809 IRC*mapAlert: true
810 IRC*font: suxuseuro
811 IRC*boldFont: suxuseuro
812 IRC*colorBD: white
813 IRC*keysym.M-C-1: command:\033]710;suxuseuro\007\033]711;suxuseuro\007
814 IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
815
816C<Alt-Ctrl-1> and C<Alt-Ctrl-2> switch between two different font
817sizes. C<suxuseuro> allows me to keep an eye (and actually read)
818stuff while keeping a very small window. If somebody pastes something
819complicated (e.g. japanese), I temporarily switch to a larger font.
820
821The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
822C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
823file for different hosts, for example, on my main desktop, I use:
824
825 URxvt.keysym.C-M-q: command:\033[3;5;5t
826 URxvt.keysym.C-M-y: command:\033[3;5;606t
827 URxvt.keysym.C-M-e: command:\033[3;1605;5t
828 URxvt.keysym.C-M-c: command:\033[3;1605;606t
829 URxvt.keysym.C-M-p: perl:test
830
831The first for keysym definitions allow me to quickly bring some windows
832in the layout I like most. Ion users might start laughing but will stop
833immediately when I tell them that I use my own Fvwm2 module for much the
834same effect as Ion provides, and I only very rarely use the above key
835combinations :->
836
837=head3 Why doesn't rxvt-unicode read my resources?
838
839Well, why, indeed? It does, in a way very similar to other X
840applications. Most importantly, this means that if you or your OS loads
841resources into the X display (the right way to do it), rxvt-unicode will
842ignore any resource files in your home directory. It will only read
843F<$HOME/.Xdefaults> when no resources are attached to the display.
844
845If you have or use an F<$HOME/.Xresources> file, chances are that
846resources are loaded into your X-server. In this case, you have to
847re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
848
849Also consider the form resources have to use:
850
851 URxvt.resource: value
852
853If you want to use another form (there are lots of different ways of
854specifying resources), make sure you understand whether and why it
855works. If unsure, use the form above.
856
857=head3 When I log-in to another system it tells me about missing terminfo data?
858
859The terminal description used by rxvt-unicode is not as widely available
860as that for xterm, or even rxvt (for which the same problem often arises).
861
862The correct solution for this problem is to install the terminfo, this can
863be done by simply installing rxvt-unicode on the remote system as well
864(in case you have a nice package manager ready), or you can install the
865terminfo database manually like this (with ncurses infocmp. works as
866user and root):
867
868 REMOTE=remotesystem.domain
869 infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
870
871One some systems you might need to set C<$TERMINFO> to the full path of
872F<$HOME/.terminfo> for this to work.
873
874If you cannot or do not want to do this, then you can simply set
875C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
876problems arising, which includes wrong keymapping, less and different
877colours and some refresh errors in fullscreen applications. It's a nice
878quick-and-dirty workaround for rare cases, though.
879
880If you always want to do this (and are fine with the consequences) you
881can either recompile rxvt-unicode with the desired TERM value or use a
882resource to set it:
883
884 URxvt.termName: rxvt
885
886If you don't plan to use B<rxvt> (quite common...) you could also replace
887the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
888
889=head3 nano fails with "Error opening terminal: rxvt-unicode"
890
891This exceptionally confusing and useless error message is printed by nano
892when it can't find the terminfo database. Nothing is wrong with your
893terminal, read the previous answer for a solution.
894
895=head3 C<tic> outputs some error when compiling the terminfo entry.
896
897Most likely it's the empty definition for C<enacs=>. Just replace it by
898C<enacs=\E[0@> and try again.
899
900=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
901
902See next entry.
903
904=head3 I need a termcap file entry.
905
906One reason you might want this is that some distributions or operating
907systems still compile some programs using the long-obsoleted termcap
908library (Fedora's bash is one example) and rely on a termcap entry
909for C<rxvt-unicode>.
910
911You could use rxvt's termcap entry with reasonable results in many cases.
912You can also create a termcap entry by using terminfo's infocmp program
913like this:
914
915 infocmp -C rxvt-unicode
916
917Or you could use the termcap entry in doc/etc/rxvt-unicode.termcap,
918generated by the command above.
919
920=head3 Why does C<ls> no longer have coloured output?
921
922The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
923decide whether a terminal has colour, but uses its own configuration
924file. Needless to say, C<rxvt-unicode> is not in its default file (among
925with most other terminals supporting colour). Either add:
926
927 TERM rxvt-unicode
928
929to C</etc/DIR_COLORS> or simply add:
930
931 alias ls='ls --color=auto'
932
933to your C<.profile> or C<.bashrc>.
934
935=head3 Why doesn't vim/emacs etc. use the 88 colour mode?
936
937See next entry.
938
939=head3 Why doesn't vim/emacs etc. make use of italic?
940
941See next entry.
942
943=head3 Why are the secondary screen-related options not working properly?
944
945Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
946distributions break rxvt-unicode by setting C<TERM> to C<rxvt>, which
947doesn't have these extra features. Unfortunately, some of these
948furthermore fail to even install the C<rxvt-unicode> terminfo file, so
949you will need to install it on your own (See the question B<When I
950log-in to another system it tells me about missing terminfo data?> on
951how to do this).
952
953
954=head2 Encoding / Locale / Input Method Issues
955
956=head3 Rxvt-unicode does not seem to understand the selected encoding?
957
958See next entry.
959
960=head3 Unicode does not seem to work?
961
962If you encounter strange problems like typing an accented character but
963getting two unrelated other characters or similar, or if program output is
964subtly garbled, then you should check your locale settings.
965
966Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
967programs running in it. Often rxvt-unicode is started in the C<C> locale,
968while the login script running within the rxvt-unicode window changes the
969locale to something else, e.g. C<en_GB.UTF-8>. Needless to say, this is
970not going to work, and is the most common cause for problems.
971
972The best thing is to fix your startup environment, as you will likely run
973into other problems. If nothing works you can try this in your .profile.
974
975 printf '\33]701;%s\007' "$LC_CTYPE" # $LANG or $LC_ALL are worth a try, too
976
977If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
978supported on your systems. Some systems have a C<locale> command which
979displays this (also, C<perl -e0> can be used to check locale settings, as
980it will complain loudly if it cannot set the locale). If it displays something
981like:
982
983 locale: Cannot set LC_CTYPE to default locale: ...
984
985Then the locale you specified is not supported on your system.
986
987If nothing works and you are sure that everything is set correctly then
988you will need to remember a little known fact: Some programs just don't
989support locales :(
990
991=head3 How does rxvt-unicode determine the encoding to use?
992
993See next entry.
994
995=head3 Is there an option to switch encodings?
996
997Unlike some other terminals, rxvt-unicode has no encoding switch, and no
998specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
999UTF-8 or any other encodings with respect to terminal I/O.
1000
1001The reasons is that there exists a perfectly fine mechanism for selecting
1002the encoding, doing I/O and (most important) communicating this to all
1003applications so everybody agrees on character properties such as width
1004and code number. This mechanism is the I<locale>. Applications not using
1005that info will have problems (for example, C<xterm> gets the width of
1006characters wrong as it uses its own, locale-independent table under all
1007locales).
1008
1009Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
1010programs doing the same (that is, most) will automatically agree in the
1011interpretation of characters.
1012
1013Unfortunately, there is no system-independent way to select locales, nor
1014is there a standard on how locale specifiers will look like.
1015
1016On most systems, the content of the C<LC_CTYPE> environment variable
1017contains an arbitrary string which corresponds to an already-installed
1018locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
1019C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
1020(i.e. C<de> or C<german>) are also common.
1021
1022Rxvt-unicode ignores all other locale categories, and except for
1023the encoding, ignores country or language-specific settings,
1024i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
1025rxvt-unicode.
1026
1027If you want to use a specific encoding you have to make sure you start
1028rxvt-unicode with the correct C<LC_CTYPE> category.
1029
1030=head3 Can I switch locales at runtime?
1031
1032Yes, using an escape sequence. Try something like this, which sets
1033rxvt-unicode's idea of C<LC_CTYPE>.
1034
1035 printf '\33]701;%s\007' ja_JP.SJIS
1036
1037See also the previous answer.
1038
1039Sometimes this capability is rather handy when you want to work in
1040one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
1041(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
1042first switches to a locale supported by xjdic and back later:
1043
1044 printf '\33]701;%s\007' ja_JP.SJIS
1045 xjdic -js
1046 printf '\33]701;%s\007' de_DE.UTF-8
1047
1048You can also use xterm's C<luit> program, which usually works fine, except
1049for some locales where character width differs between program- and
1050rxvt-unicode-locales.
1051
1052=head3 I have problems getting my input method working.
1053
1054Try a search engine, as this is slightly different for every input method server.
1055
1056Here is a checklist:
1057
1058=over 4
1059
1060=item - Make sure your locale I<and> the imLocale are supported on your OS.
1061
1062Try C<locale -a> or check the documentation for your OS.
1063
1064=item - Make sure your locale or imLocale matches a locale supported by your XIM.
1065
1066For example, B<kinput2> does not support UTF-8 locales, you should use
1067C<ja_JP.EUC-JP> or equivalent.
1068
1069=item - Make sure your XIM server is actually running.
1070
1071=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
1072
1073When you want to use e.g. B<kinput2>, it must be set to
1074C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input
1075method servers are running with this command:
1076
1077 xprop -root XIM_SERVERS
894 1078
895=back 1079=back
896 1080
1081=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
1082
1083You can specify separate locales for the input method and the rest of the
1084terminal, using the resource C<imlocale>:
1085
1086 URxvt.imlocale: ja_JP.EUC-JP
1087
1088Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
1089use your input method. Please note, however, that, depending on your Xlib
1090version, you may not be able to input characters outside C<EUC-JP> in a
1091normal way then, as your input method limits you.
1092
1093=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
1094
1095Unfortunately, this is unavoidable, as the XIM protocol is racy by
1096design. Applications can avoid some crashes at the expense of memory
1097leaks, and Input Methods can avoid some crashes by careful ordering at
1098exit time. B<kinput2> (and derived input methods) generally succeeds,
1099while B<SCIM> (or similar input methods) fails. In the end, however,
1100crashes cannot be completely avoided even if both sides cooperate.
1101
1102So the only workaround is not to kill your Input Method Servers.
1103
1104
1105=head2 Operating Systems / Package Maintaining
1106
1107=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
1108
1109You should build one binary with the default options. F<configure>
1110now enables most useful options, and the trend goes to making them
1111runtime-switchable, too, so there is usually no drawback to enabling them,
1112except higher disk and possibly memory usage. The perl interpreter should
1113be enabled, as important functionality (menus, selection, likely more in
1114the future) depends on it.
1115
1116You should not overwrite the C<perl-ext-common> and C<perl-ext> resources
1117system-wide (except maybe with C<defaults>). This will result in useful
1118behaviour. If your distribution aims at low memory, add an empty
1119C<perl-ext-common> resource to the app-defaults file. This will keep the
1120perl interpreter disabled until the user enables it.
1121
1122If you can/want build more binaries, I recommend building a minimal
1123one with C<--disable-everything> (very useful) and a maximal one with
1124C<--enable-everything> (less useful, it will be very big due to a lot of
1125encodings built-in that increase download times and are rarely used).
1126
1127=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
1128
1129It should be, starting with release 7.1. You are encouraged to properly
1130install urxvt with privileges necessary for your OS now.
1131
1132When rxvt-unicode detects that it runs setuid or setgid, it will fork
1133into a helper process for privileged operations (pty handling on some
1134systems, utmp/wtmp/lastlog handling on others) and drop privileges
1135immediately. This is much safer than most other terminals that keep
1136privileges while running (but is more relevant to urxvt, as it contains
1137things as perl interpreters, which might be "helpful" to attackers).
1138
1139This forking is done as the very first within main(), which is very early
1140and reduces possible bugs to initialisation code run before main(), or
1141things like the dynamic loader of your system, which should result in very
1142little risk.
1143
1144=head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
1145
1146Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
1147in your compile environment, or an implementation that implements it,
1148whether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
1149B<wchar_t> is represented as unicode.
1150
1151As you might have guessed, FreeBSD does neither define this symbol nor
1152does it support it. Instead, it uses its own internal representation of
1153B<wchar_t>. This is, of course, completely fine with respect to standards.
1154
1155However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
1156C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>).
1157
1158C<__STDC_ISO_10646__> is the only sane way to support multi-language
1159apps in an OS, as using a locale-dependent (and non-standardized)
1160representation of B<wchar_t> makes it impossible to convert between
1161B<wchar_t> (as used by X11 and your applications) and any other encoding
1162without implementing OS-specific-wrappers for each and every locale. There
1163simply are no APIs to convert B<wchar_t> into anything except the current
1164locale encoding.
1165
1166Some applications (such as the formidable B<mlterm>) work around this
1167by carrying their own replacement functions for character set handling
1168with them, and either implementing OS-dependent hacks or doing multiple
1169conversions (which is slow and unreliable in case the OS implements
1170encodings slightly different than the terminal emulator).
1171
1172The rxvt-unicode author insists that the right way to fix this is in the
1173system libraries once and for all, instead of forcing every app to carry
1174complete replacements for them :)
1175
1176=head3 How can I use rxvt-unicode under cygwin?
1177
1178rxvt-unicode should compile and run out of the box on cygwin, using
1179the X11 libraries that come with cygwin. libW11 emulation is no
1180longer supported (and makes no sense, either, as it only supported a
1181single font). I recommend starting the X-server in C<-multiwindow> or
1182C<-rootless> mode instead, which will result in similar look&feel as the
1183old libW11 emulation.
1184
1185At the time of this writing, cygwin didn't seem to support any multi-byte
1186encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited

1189=head3 Character widths are not correct.
1190
1191urxvt uses the system wcwidth function to know the information about
1192the width of characters, so on systems with incorrect locale data you
1193will likely get bad results. Two notorious examples are Solaris 9,
1194where single-width characters like U+2514 are reported as double-width,
1195and Darwin 8, where combining chars are reported having width 1.
1196
1197The solution is to upgrade your system or switch to a better one. A
1198possibly working workaround is to use a wcwidth implementation like

1989Changes all mouse reporting codes to use decimal parameters instead of
1990octets or characters.
1991
1992This mode should be enabled I<before> actually enabling mouse reporting,
1993for semi-obvious reasons.
1994
1995The sequences received for various modes are as follows:
1996
1997 ESC [ M o o o !1005, !1015 (three octets)
1998 ESC [ M c c c 1005, !1015 (three characters)
1999 ESC [ Pm M 1015 (three or more numeric parameters)
2000
2001The first three parameters are C<code>, C<x> and C<y>. Code is the numeric
2002code as for the other modes (but encoded as a decimal number, including
2003the additional offset of 32, so you have to subtract 32 first), C<x> and
2004C<y> are the coordinates (1|1 is the upper left corner, just as with
2005cursor positioning).
2006
2007Example: Shift-Button-1 press at top row, column 80.
2008
2009 ESC [ 37 ; 80 ; 1 M
2010
2011One can use this feature by simply enabling it and then looking for
2012parameters to the C<ESC [ M> reply - if there are any, this mode is
2013active, otherwise one of the old reporting styles is used.
2014
2015Other (to be implemented) reply sequences will use a similar encoding.
2016
2017In the future, more parameters might get added (pixel coordinates for
2018example - anybody out there who needs this?).
