17		17
		18	This document contains the FAQ, the RXVT TECHNICAL REFERENCE documenting
		19	all escape sequences, and other background information.
		20
		21	The newest version of this document is
		22	also available on the World Wide Web at
		23	L<http://cvs.schmorp.de/browse/*checkout*/rxvt-unicode/doc/rxvt.7.html>.
		24
		25	=head1 FREQUENTLY ASKED QUESTIONS
		26
		27	=over 4
		28
		29	=item The new selection selects pieces that are too big, how can I select
		30	single words?
		31
		32	Yes. For example, if you want to select alphanumeric words, you can use
		33	the following resource:
		34
		35	URxvt.selection.pattern-0: ([[:word:]]+)
		36
		37	If you click more than twice, the selection will be extended
		38	more and more.
		39
		40	To get a selection that is very similar to the old code, try this pattern:
		41
		42	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		43
		44	Please also note that the I<LeftClick Shift-LeftClik> combination also
		45	selects words like the old code.
		46
		47	=item I don't like the new selection/popups/hotkeys/perl, how do I
		48	change/disable it?
		49
		50	You can disable the perl extension completely by setting the
		51	B<perl-ext-common> resource to the empty string, which also keeps
		52	rxvt-unicode from initialising perl, saving memory.
		53
		54	If you only want to disable specific features, you first have to
		55	identify which perl extension is responsible. For this, read the section
		56	B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
		57	example, to disable the B<selection-popup> and B<option-popup>, specify
		58	this B<perl-ext-common> resource:
		59
		60	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		61
		62	This will keep the default extensions, but disable the two popup
		63	extensions. Some extensions can also be configured, for example,
		64	scrollback search mode is triggered by B<M-s>. You can move it to any
		65	other combination either by setting the B<searchable-scrollback> resource:
		66
		67	URxvt.searchable-scrollback: CM-s
		68
		69	=item Isn't rxvt supposed to be small? Don't all those features bloat?
		70
		71	I often get asked about this, and I think, no, they didn't cause extra
		72	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		73	that the urxvt binary is larger (due to some encoding tables always being
		74	compiled in), but it actually uses less memory (RSS) after startup. Even
		75	with C<--disable-everything>, this comparison is a bit unfair, as many
		76	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		77	already in use in this mode.
		78
		79	text data bss drs rss filename
		80	98398 1664 24 15695 1824 rxvt --disable-everything
		81	188985 9048 66616 18222 1788 urxvt --disable-everything
		82
		83	When you C<--enable-everything> (which _is_ unfair, as this involves xft
		84	and full locale/XIM support which are quite bloaty inside libX11 and my
		85	libc), the two diverge, but not unreasnobaly so.
		86
		87	text data bss drs rss filename
		88	163431 2152 24 20123 2060 rxvt --enable-everything
		89	1035683 49680 66648 29096 3680 urxvt --enable-everything
		90
		91	The very large size of the text section is explained by the east-asian
		92	encoding tables, which, if unused, take up disk space but nothing else
		93	and can be compiled out unless you rely on X11 core fonts that use those
		94	encodings. The BSS size comes from the 64k emergency buffer that my c++
		95	compiler allocates (but of course doesn't use unless you are out of
		96	memory). Also, using an xft font instead of a core font immediately adds a
		97	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		98	not used.
		99
		100	Of course, due to every character using two or four bytes instead of one,
		101	a large scrollback buffer will ultimately make rxvt-unicode use more
		102	memory.
		103
		104	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		105	still fares rather well. And compared to some monsters like gnome-terminal
		106	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		107	43180k in daemons that stay around after exit, plus half a minute of
		108	startup time, including the hundreds of warnings it spits out), it fares
		109	extremely well *g*.
		110
		111	=item Why C++, isn't that unportable/bloated/uncool?
		112
		113	Is this a question? :) It comes up very often. The simple answer is: I had
		114	to write it, and C++ allowed me to write and maintain it in a fraction
		115	of the time and effort (which is a scarce resource for me). Put even
		116	shorter: It simply wouldn't exist without C++.
		117
		118	My personal stance on this is that C++ is less portable than C, but in
		119	the case of rxvt-unicode this hardly matters, as its portability limits
		120	are defined by things like X11, pseudo terminals, locale support and unix
		121	domain sockets, which are all less portable than C++ itself.
		122
		123	Regarding the bloat, see the above question: It's easy to write programs
		124	in C that use gobs of memory, an certainly possible to write programs in
		125	C++ that don't. C++ also often comes with large libraries, but this is
		126	not necessarily the case with GCC. Here is what rxvt links against on my
		127	system with a minimal config:
		128
		129	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		130	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		131	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		132	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		133
		134	And here is rxvt-unicode:
		135
		136	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		137	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		138	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		139	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		140	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		141
		142	No large bloated libraries (of course, none were linked in statically),
		143	except maybe libX11 :)
		144
		145	=item Does it support tabs, can I have a tabbed rxvt-unicode?
		146
		147	rxvt-unicode does not directly support tabs. It will work fine with
		148	tabbing functionality of many window managers or similar tabbing programs,
		149	and its embedding-features allow it to be embedded into other programs,
		150	as witnessed by F<doc/rxvt-tabbed> or the upcoming C<Gtk2::URxvt> perl
		151	module, which features a tabbed urxvt (murxvt) terminal as an example
		152	embedding application.
		153
		154	=item How do I know which rxvt-unicode version I'm using?
		155
		156	The version number is displayed with the usage (-h). Also the escape
		157	sequence C<ESC [ 8 n> sets the window title to the version number. When
		158	using the @@RXVT_NAME@@c client, the version displayed is that of the
		159	daemon.
		160
		161	=item I am using Debian GNU/Linux and have a problem...
		162
		163	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		164	patches that considerably change the behaviour of rxvt-unicode (but
		165	unfortunately this notice has been removed). Before reporting a bug to
		166	the original rxvt-unicode author please download and install the genuine
		167	version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
		168	the problem. If you cannot, chances are that the problems are specific to
		169	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		170	Tracking System (use C<reportbug> to report the bug).
		171
		172	For other problems that also affect the Debian package, you can and
		173	probably should use the Debian BTS, too, because, after all, it's also a
		174	bug in the Debian version and it serves as a reminder for other users that
		175	might encounter the same issue.
		176
		177	=item I am maintaining rxvt-unicode for distribution/OS XXX, any
		178	recommendation?
		179
		180	You should build one binary with the default options. F<configure>
		181	now enables most useful options, and the trend goes to making them
		182	runtime-switchable, too, so there is usually no drawback to enbaling them,
		183	except higher disk and possibly memory usage. The perl interpreter should
		184	be enabled, as important functionality (menus, selection, likely more in
		185	the future) depends on it.
		186
		187	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		188	system-wide (except maybe with C<defaults>). This will result in useful
		189	behaviour. If your distribution aims at low memory, add an empty
		190	C<perl-ext-common> resource to the app-defaults file. This will keep the
		191	perl interpreter disabled until the user enables it.
		192
		193	If you can/want build more binaries, I recommend building a minimal
		194	one with C<--disable-everything> (very useful) and a maximal one with
		195	C<--enable-everything> (less useful, it will be very big due to a lot of
		196	encodings built-in that increase download times and are rarely used).
		197
		198	=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		199
		200	It should be, starting with release 7.1. You are encouraged to properly
		201	install urxvt with privileges necessary for your OS now.
		202
		203	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		204	into a helper process for privileged operations (pty handling on some
		205	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		206	immediately. This is much safer than most other terminals that keep
		207	privileges while running (but is more relevant to urxvt, as it contains
		208	things as perl interpreters, which might be "helpful" to attackers).
		209
		210	This forking is done as the very first within main(), which is very early
		211	and reduces possible bugs to initialisation code run before main(), or
		212	things like the dynamic loader of your system, which should result in very
		213	little risk.
		214
		215	=item When I log-in to another system it tells me about missing terminfo data?
		216
		217	The terminal description used by rxvt-unicode is not as widely available
		218	as that for xterm, or even rxvt (for which the same problem often arises).
		219
		220	The correct solution for this problem is to install the terminfo, this can
		221	be 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
		228	If you cannot or do not want to do this, then you can simply set
		229	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		230	problems arising, which includes wrong keymapping, less and different
		231	colours and some refresh errors in fullscreen applications. It's a nice
		232	quick-and-dirty workaround for rare cases, though.
		233
		234	If you always want to do this (and are fine with the consequences) you
		235	can either recompile rxvt-unicode with the desired TERM value or use a
		236	resource to set it:
		237
		238	URxvt.termName: rxvt
		239
		240	If you don't plan to use B<rxvt> (quite common...) you could also replace
		241	the rxvt terminfo file with the rxvt-unicode one.
		242
		243	=item C<tic> outputs some error when compiling the terminfo entry.
		244
		245	Most likely it's the empty definition for C<enacs=>. Just replace it by
		246	C<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
		252	One reason you might want this is that some distributions or operating
		253	systems still compile some programs using the long-obsoleted termcap
		254	library (Fedora Core's bash is one example) and rely on a termcap entry
		255	for C<rxvt-unicode>.
		256
		257	You could use rxvt's termcap entry with resonable results in many cases.
		258	You can also create a termcap entry by using terminfo's infocmp program
		259	like this:
		260
		261	infocmp -C rxvt-unicode
		262
		263	Or you could use this termcap entry, generated by the command above:
		264
		265	rxvt-unicode|rxvt-unicode terminal (X Window System):\

		285
		286	=item Why does C<ls> no longer have coloured output?
		287
		288	The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
		289	decide wether a terminal has colour, but uses it's own configuration
		290	file. Needless to say, C<rxvt-unicode> is not in it's default file (among
		291	with most other terminals supporting colour). Either add:
		292
		293	TERM rxvt-unicode
		294
		295	to C</etc/DIR_COLORS> or simply add:
		296
		297	alias ls='ls --color=auto'
		298
		299	to your C<.profile> or C<.bashrc>.
		300
		301	=item Why doesn't vim/emacs etc. use the 88 colour mode?
		302
		303	=item Why doesn't vim/emacs etc. make use of italic?
		304
		305	=item Why are the secondary screen-related options not working properly?
		306
		307	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		308	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		309	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		310	features. Unfortunately, some of these (most notably, again, Debian
		311	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		312	file, so you will need to install it on your own (See the question B<When
		313	I log-in to another system it tells me about missing terminfo data?> on
		314	how to do this).
		315
		316	=item My numerical keypad acts weird and generates differing output?
		317
		318	Some Debian GNUL/Linux users seem to have this problem, although no
		319	specific details were reported so far. It is possible that this is caused
		320	by the wrong C<TERM> setting, although the details of wether and how
		321	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		322	keymap. See the answer to the previous question, and please report if that
		323	helped.
		324
		325	=item Rxvt-unicode does not seem to understand the selected encoding?
		326
		327	=item Unicode does not seem to work?
		328
		329	If you encounter strange problems like typing an accented character but
		330	getting two unrelated other characters or similar, or if program output is
		331	subtly garbled, then you should check your locale settings.
		332
		333	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		334	programs. Often rxvt-unicode is started in the C<C> locale, while the
		335	login script running within the rxvt-unicode window changes the locale to
		336	something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
		337
		338	The best thing is to fix your startup environment, as you will likely run
		339	into other problems. If nothing works you can try this in your .profile.
		340
		341	printf '\e]701;%s\007' "$LC_CTYPE"
		342
		343	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		344	supported on your systems. Some systems have a C<locale> command which
		345	displays this (also, C<perl -e0> can be used to check locale settings, as
		346	it will complain loudly if it cannot set the locale). If it displays something
		347	like:
		348
		349	locale: Cannot set LC_CTYPE to default locale: ...
		350
		351	Then the locale you specified is not supported on your system.
		352
		353	If nothing works and you are sure that everything is set correctly then
		354	you will need to remember a little known fact: Some programs just don't
		355	support locales :(
		356
		357	=item Why do some characters look so much different than others?
		358
		359	=item How does rxvt-unicode choose fonts?
		360
		361	Most fonts do not contain the full range of Unicode, which is
		362	fine. Chances are that the font you (or the admin/package maintainer of
		363	your system/os) have specified does not cover all the characters you want
		364	to display.
		365
		366	B<rxvt-unicode> makes a best-effort try at finding a replacement
		367	font. Often the result is fine, but sometimes the chosen font looks
		368	bad/ugly/wrong. Some fonts have totally strange characters that don't
		369	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		370	intelligence to detect that a specific glyph is wrong: it has to believe
		371	the font that the characters it claims to contain indeed look correct.
		372
		373	In that case, select a font of your taste and add it to the font list,
		374	e.g.:
		375
		376	@@RXVT_NAME@@ -fn basefont,font2,font3...
		377
		378	When rxvt-unicode sees a character, it will first look at the base
		379	font. If the base font does not contain the character, it will go to the
		380	next font, and so on. Specifying your own fonts will also speed up this
		381	search and use less resources within rxvt-unicode and the X-server.
		382
		383	The only limitation is that none of the fonts may be larger than the base
		384	font, as the base font defines the terminal character cell size, which
		385	must be the same due to the way terminals work.
		386
		387	=item Why do some chinese characters look so different than others?
		388
		389	This is because there is a difference between script and language --
		390	rxvt-unicode does not know which language the text that is output is,
		391	as it only knows the unicode character codes. If rxvt-unicode first
		392	sees a japanese/chinese character, it might choose a japanese font for
		393	display. Subsequent japanese characters will use that font. Now, many
		394	chinese characters aren't represented in japanese fonts, so when the first
		395	non-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
		397	chinese characters that are also in the japanese font.
		398
		399	The workaround is easy: just tag a chinese font at the end of your font
		400	list (see the previous question). The key is to view the font list as
		401	a preference list: If you expect more japanese, list a japanese font
		402	first. If you expect more chinese, put a chinese font first.
		403
		404	In the future it might be possible to switch language preferences at
		405	runtime (the internal data structure has no problem with using different
		406	fonts for the same character at the same time, but no interface for this
		407	has been designed yet).
		408
		409	Until then, you might get away with switching fonts at runtime (see L<Can
		410	I switch the fonts at runtime?> later in this document).
		411
		412	=item Why does rxvt-unicode sometimes leave pixel droppings?
		413
		414	Most fonts were not designed for terminal use, which means that character
		415	size varies a lot. A font that is otherwise fine for terminal use might
		416	contain some characters that are simply too wide. Rxvt-unicode will avoid
		417	these characters. For characters that are just "a bit" too wide a special
		418	"careful" rendering mode is used that redraws adjacent characters.
		419
		420	All of this requires that fonts do not lie about character sizes,
		421	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		422	box, and rxvt-unicode has no way of detecting this (the correct way is to
		423	ask for the character bounding box, which unfortunately is wrong in these
		424	cases).
		425
		426	It's not clear (to me at least), wether this is a bug in Xft, freetype,
		427	or the respective font. If you encounter this problem you might try using
		428	the C<-lsp> option to give the font more height. If that doesn't work, you
		429	might be forced to use a different font.
		430
		431	All of this is not a problem when using X11 core fonts, as their bounding
		432	box data is correct.
		433
		434	=item On Solaris 9, many line-drawing characters are too wide.
		435
		436	Seems to be a known bug, read
		437	L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
		438	following ugly workaround to get non-double-wide-characters working:
		439
		440	#define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
		441
		442	=item My Compose (Multi_key) key is no longer working.
		443
		444	The most common causes for this are that either your locale is not set
		445	correctly, or you specified a B<preeditStyle> that is not supported by
		446	your input method. For example, if you specified B<OverTheSpot> and
		447	your input method (e.g. the default input method handling Compose keys)
		448	does not support this (for instance because it is not visual), then
		449	rxvt-unicode will continue without an input method.
		450
		451	In this case either do not specify a B<preeditStyle> or specify more than
		452	one pre-edit style, such as B<OverTheSpot,Root,None>.
		453
		454	=item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		455
		456	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		457	international keyboards) or simply use ISO 14755 support to your
		458	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		459	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		460	character and so on.
		461
		462	=item How can I keep rxvt-unicode from using reverse video so much?
		463
		464	First of all, make sure you are running with the right terminal settings
		465	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		466	make sure you have specified colours for italic and bold, as otherwise
		467	rxvt-unicode might use reverse video to simulate the effect:
		468
		469	URxvt.colorBD: white
		470	URxvt.colorIT: green
		471
		472	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
		473
		474	For some unexplainable reason, some rare programs assume a very weird
		475	colour palette when confronted with a terminal with more than the standard
		476	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		477	these programs not to assume non-ISO colours without very good reasons.
		478
		479	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		480	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		481	fix colours but keep you from using other rxvt-unicode features.
		482
		483	=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
		484
		485	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
		486	in your compile environment, or an implementation that implements it,
		487	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
		488	B<wchar_t> is represented as unicode.
		489
		490	As you might have guessed, FreeBSD does neither define this symobl nor
		491	does it support it. Instead, it uses it's own internal representation of
		492	B<wchar_t>. This is, of course, completely fine with respect to standards.
		493
		494	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		495	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
		496
		497	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		498	apps in an OS, as using a locale-dependent (and non-standardized)
		499	representation of B<wchar_t> makes it impossible to convert between
		500	B<wchar_t> (as used by X11 and your applications) and any other encoding
		501	without implementing OS-specific-wrappers for each and every locale. There
		502	simply are no APIs to convert B<wchar_t> into anything except the current
		503	locale encoding.
		504
		505	Some applications (such as the formidable B<mlterm>) work around this
		506	by carrying their own replacement functions for character set handling
		507	with them, and either implementing OS-dependent hacks or doing multiple
		508	conversions (which is slow and unreliable in case the OS implements
		509	encodings slightly different than the terminal emulator).
		510
		511	The rxvt-unicode author insists that the right way to fix this is in the
		512	system libraries once and for all, instead of forcing every app to carry
		513	complete replacements for them :)
		514
		515	=item I use Solaris 9 and it doesn't compile/work/etc.
		516
		517	Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
		518	problems with C<wcwidth> and a compile problem.
		519
		520	=item How can I use rxvt-unicode under cygwin?
		521
		522	rxvt-unicode should compile and run out of the box on cygwin, using
		523	the X11 libraries that come with cygwin. libW11 emulation is no
		524	longer supported (and makes no sense, either, as it only supported a
		525	single font). I recommend starting the X-server in C<-multiwindow> or
		526	C<-rootless> mode instead, which will result in similar look&feel as the
		527	old libW11 emulation.
		528
		529	At the time of this writing, cygwin didn't seem to support any multi-byte
		530	encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
		531	to 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
		537	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		538	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		539	UTF-8 or any other encodings with respect to terminal I/O.
		540
		541	The reasons is that there exists a perfectly fine mechanism for selecting
		542	the encoding, doing I/O and (most important) communicating this to all
		543	applications so everybody agrees on character properties such as width
		544	and code number. This mechanism is the I<locale>. Applications not using
		545	that info will have problems (for example, C<xterm> gets the width of
		546	characters wrong as it uses it's own, locale-independent table under all
		547	locales).
		548
		549	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		550	programs doing the same (that is, most) will automatically agree in the
		551	interpretation of characters.
		552
		553	Unfortunately, there is no system-independent way to select locales, nor
		554	is there a standard on how locale specifiers will look like.
		555
		556	On most systems, the content of the C<LC_CTYPE> environment variable
		557	contains an arbitrary string which corresponds to an already-installed
		558	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		559	C<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
		562	Rxvt-unicode ignores all other locale categories, and except for
		563	the encoding, ignores country or language-specific settings,
		564	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		565	rxvt-unicode.
		566
		567	If you want to use a specific encoding you have to make sure you start
		568	rxvt-unicode with the correct C<LC_CTYPE> category.
		569
		570	=item Can I switch locales at runtime?
		571
		572	Yes, using an escape sequence. Try something like this, which sets
		573	rxvt-unicode's idea of C<LC_CTYPE>.
		574
		575	printf '\e]701;%s\007' ja_JP.SJIS
		576
		577	See also the previous answer.
		578
		579	Sometimes this capability is rather handy when you want to work in
		580	one 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
		582	first 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
		588	You can also use xterm's C<luit> program, which usually works fine, except
		589	for some locales where character width differs between program- and
		590	rxvt-unicode-locales.
		591
		592	=item Can I switch the fonts at runtime?
		593
		594	Yes, using an escape sequence. Try something like this, which has the same
		595	effect as using the C<-fn> switch, and takes effect immediately:
		596
		597	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
		598
		599	This is useful if you e.g. work primarily with japanese (and prefer a
		600	japanese font), but you have to switch to chinese temporarily, where
		601	japanese fonts would only be in your way.
		602
		603	You can think of this as a kind of manual ISO-2022 switching.
		604
		605	=item Why do italic characters look as if clipped?
		606
		607	Many fonts have difficulties with italic characters and hinting. For
		608	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		609	Mono> completely fails in it's italic face. A workaround might be to
		610	enable freetype autohinting, i.e. like this:
		611
		612	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		613	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		614
		615	=item My input method wants <some encoding> but I want UTF-8, what can I do?
		616
		617	You can specify separate locales for the input method and the rest of the
		618	terminal, using the resource C<imlocale>:
		619
		620	URxvt.imlocale: ja_JP.EUC-JP
		621
		622	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		623	use your input method. Please note, however, that you will not be able to
		624	input characters outside C<EUC-JP> in a normal way then, as your input
		625	method limits you.
		626
		627	=item Rxvt-unicode crashes when the X Input Method changes or exits.
		628
		629	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		630	design. Applications can avoid some crashes at the expense of memory
		631	leaks, and Input Methods can avoid some crashes by careful ordering at
		632	exit time. B<kinput2> (and derived input methods) generally succeeds,
		633	while B<SCIM> (or similar input methods) fails. In the end, however,
		634	crashes cannot be completely avoided even if both sides cooperate.
		635
		636	So 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
		640	Rxvt-unicode tries to obey the rule of not charging you for something you
		641	don't use. One thing you should try is to configure out all settings that
		642	you don't need, for example, Xft support is a resource hog by design,
		643	when used. Compiling it out ensures that no Xft font will be loaded
		644	accidentally when rxvt-unicode tries to find a font for your characters.
		645
		646	Also, many people (me included) like large windows and even larger
		647	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
		648	6 bytes per screen cell. For a 160x?? window this amounts to almost a
		649	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
		650	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
		651	rxvt-unicode then uses 8 bytes per screen cell.
		652
		653	=item Can I speed up Xft rendering somehow?
		654
		655	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		656	it is simply slow. If you still want Xft fonts you might try to disable
		657	antialiasing (by appending C<:antialias=false>), which saves lots of
		658	memory and also speeds up rendering considerably.
		659
		660	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		661
		662	Rxvt-unicode will use whatever you specify as a font. If it needs to
		663	fall back to it's default font search list it will prefer X11 core
		664	fonts, because they are small and fast, and then use Xft fonts. It has
		665	antialiasing disabled for most of them, because the author thinks they
		666	look best that way.
		667
		668	If you want antialiasing, you have to specify the fonts manually.
		669
		670	=item Mouse cut/paste suddenly no longer works.
		671
		672	Make sure that mouse reporting is actually turned off since killing
		673	some editors prematurely may leave the mouse in mouse report mode. I've
		674	heard that tcsh may use mouse reporting unless it otherwise specified. A
		675	quick check is to see if cut/paste works when the Alt or Shift keys are
		676	depressed.
		677
		678	=item What's with this bold/blink stuff?
		679
		680	If no bold colour is set via C<colorBD:>, bold will invert text using the
		681	standard foreground colour.
		682
		683	For the standard background colour, blinking will actually make the
		684	text blink when compiled with C<--enable-blinking>. with standard
		685	colours. Without C<--enable-blinking>, the blink attribute will be
		686	ignored.
		687
		688	On ANSI colours, bold/blink attributes are used to set high-intensity
		689	foreground/background colors.
		690
		691	color0-7 are the low-intensity colors.
		692
		693	color8-15 are the corresponding high-intensity colors.
		694
		695	=item I don't like the screen colors. How do I change them?
		696
		697	You can change the screen colors at run-time using F<~/.Xdefaults>
		698	resources (or as long-options).
		699
		700	Here are values that are supposed to resemble a VGA screen,
		701	including the murky brown that passes for low-intensity yellow:
		702

		747
		748	=item What's with the strange Backspace/Delete key behaviour?
		749
		750	Assuming that the physical Backspace key corresponds to the
		751	BackSpace keysym (not likely for Linux ... see the following
		752	question) there are two standard values that can be used for
		753	Backspace: C<^H> and C<^?>.
		754
		755	Historically, either value is correct, but rxvt-unicode adopts the debian
		756	policy of using C<^?> when unsure, because it's the one only only correct
		757	choice :).
		758
		759	Rxvt-unicode tries to inherit the current stty settings and uses the value
		760	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
		761	started from a terminal (say, from a menu or by remote shell), then the
		762	system value of `erase', which corresponds to CERASE in <termios.h>, will
		763	be used (which may not be the same as your stty setting).
		764
		765	For starting a new rxvt-unicode:
		766
		767	# use Backspace = ^H
		768	$ stty erase ^H
		769	$ @@RXVT_NAME@@
		770
		771	# use Backspace = ^?
		772	$ stty erase ^?
		773	$ @@RXVT_NAME@@
		774
		775	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
		776
		777	For an existing rxvt-unicode:
		778
		779	# use Backspace = ^H
		780	$ stty erase ^H
		781	$ echo -n "^[[36h"
		782
		783	# use Backspace = ^?
		784	$ stty erase ^?
		785	$ echo -n "^[[36l"
		786
		787	This helps satisfy some of the Backspace discrepancies that occur, but
		788	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
		789	properly reflects that.
		790
		791	The Delete key is a another casualty of the ill-defined Backspace problem.
		792	To avoid confusion between the Backspace and Delete keys, the Delete
		793	key has been assigned an escape sequence to match the vt100 for Execute
		794	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
		795
		796	Some other Backspace problems:
		797
		798	some editors use termcap/terminfo,
		799	some editors (vim I'm told) expect Backspace = ^H,
		800	GNU Emacs (and Emacs-like editors) use ^H for help.
		801
		802	Perhaps someday this will all be resolved in a consistent manner.
		803
		804	=item I don't like the key-bindings. How do I change them?

		846	Rather than have rxvt-unicode try to accommodate all the various possible
		847	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		848	required for your particular machine.

		850	=item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
		851	I need this to decide about setting colors etc.
		852
		853	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
		854	check and see if that is set. Note that several programs, JED, slrn,
		855	Midnight Commander automatically check this variable to decide whether or
		856	not to use color.
		857
		858	=item How do I set the correct, full IP address for the DISPLAY variable?
		859
		860	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		861	insecure mode then it is possible to use the following shell script
		862	snippets to correctly set the display. If your version of rxvt-unicode
		863	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		864	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		865	regular xterm.

791	In the menus, B<DON'T> try to use menuBar commands that add or remove a
792	menuBar.

796
797	=head2 Overview of menuBar operation
798
799	For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
800	of C<Pt> can be used for a variety of tasks:
801
802	At the top level is the current menuBar which is a member of a circular
803	linked-list of other such menuBars.
804
805	The menuBar acts as a parent for the various drop-down menus, which in
806	turn, may have labels, separator lines, menuItems and subMenus.
807
808	The menuItems are the useful bits: you can use them to mimic keyboard
809	input or even to send text or escape sequences back to rxvt.
810
811	The menuBar syntax is intended to provide a simple yet robust method of
812	constructing and manipulating menus and navigating through the
813	menuBars.
814
815	The first step is to use the tag B<< [menu:I<name>] >> which creates
816	the menuBar called I<name> and allows access. You may now or menus,
817	subMenus, and menuItems. Finally, use the tag B<[done]> to set the
818	menuBar access as B<readonly> to prevent accidental corruption of the
819	menus. To re-access the current menuBar for alterations, use the tag
820	B<[menu]>, make the alterations and then use B<[done]>

855	[menu:+I<name> >> and continuing until B<[done]> is encountered.
856
857	Blank and comment lines (starting with B<#>) are ignored. Actually,
858	since any invalid menu commands are also ignored, almost anything could
859	be construed as a comment line, but this may be tightened up in the
860	future ... so don't count on it!.
