		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 Isn't rxvt supposed to be small? Don't all those features bloat?
		30
		31	I often get asked about this, and I think, no, they didn't cause extra
		32	bloat. If you compare a minimal rxvt and a minimal urxvt, you can see
		33	that the urxvt binary is larger (due to some encoding tables always being
		34	compiled in), but it actually uses less memory (RSS) after startup. Even
		35	with C<--disable-everything>, this comparison is a bit unfair, as many
		36	features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
		37	already in use in this mode.
		38
		39	text data bss drs rss filename
		40	98398 1664 24 15695 1824 rxvt --disable-everything
		41	188985 9048 66616 18222 1788 urxvt --disable-everything
		42
		43	When you C<--enable-everything> (which _is_ unfair, as this involves xft
		44	and full locale/XIM support which are quite bloaty inside libX11 and my
		45	libc), the two diverge, but not unreasnobaly so.
		46
		47	text data bss drs rss filename
		48	163431 2152 24 20123 2060 rxvt --enable-everything
		49	1035683 49680 66648 29096 3680 urxvt --enable-everything
		50
		51	The very large size of the text section is explained by the east-asian
		52	encoding tables, which, if unused, take up disk space but nothing else
		53	and can be compiled out unless you rely on X11 core fonts that use those
		54	encodings. The BSS size comes from the 64k emergency buffer that my c++
		55	compiler allocates (but of course doesn't use unless you are out of
		56	memory). Also, using an xft font instead of a core font immediately adds a
		57	few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
		58	not used.
		59
		60	Of course, due to every character using two or four bytes instead of one,
		61	a large scrollback buffer will ultimately make rxvt-unicode use more
		62	memory.
		63
		64	Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
		65	still fares rather well. And compared to some monsters like gnome-terminal
		66	(21152k + extra 4204k in separate processes) or konsole (22200k + extra
		67	43180k in daemons that stay around after exit, plus half a minute of
		68	startup time, including the hundreds of warnings it spits out), it fares
		69	extremely well *g*.
		70
		71	=item Why C++, isn't that unportable/bloated/uncool?
		72
		73	Is this a question? :) It comes up very often. The simple answer is: I had
		74	to write it, and C++ allowed me to write and maintain it in a fraction
		75	of the time and effort (which is a scarce resource for me). Put even
		76	shorter: It simply wouldn't exist without C++.
		77
		78	My personal stance on this is that C++ is less portable than C, but in
		79	the case of rxvt-unicode this hardly matters, as its portability limits
		80	are defined by things like X11, pseudo terminals, locale support and unix
		81	domain sockets, which are all less portable than C++ itself.
		82
		83	Regarding the bloat, see the above question: It's easy to write programs
		84	in C that use gobs of memory, an certainly possible to write programs in
		85	C++ that don't. C++ also often comes with large libraries, but this is
		86	not necessarily the case with GCC. Here is what rxvt links against on my
		87	system with a minimal config:
		88
		89	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		90	libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
		91	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
		92	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		93
		94	And here is rxvt-unicode:
		95
		96	libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
		97	libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
		98	libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
		99	libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
		100	/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
		101
		102	No large bloated libraries (of course, none were linked in statically),
		103	except maybe libX11 :)
		104
		105	=item Does it support tabs, can I have a tabbed rxvt-unicode?
		106
		107	rxvt-unicode does not directly support tabs. It will work fine with
		108	tabbing functionality of many window managers or similar tabbing programs,
		109	and its embedding-features allow it to be embedded into other programs,
		110	as witnessed by F<doc/rxvt-tabbed> or the upcoming C<Gtk2::URxvt> perl
		111	module, which features a tabbed urxvt (murxvt) terminal as an example
		112	embedding application.
		113
		114	=item How do I know which rxvt-unicode version I'm using?
		115
		116	The version number is displayed with the usage (-h). Also the escape
		117	sequence C<ESC [ 8 n> sets the window title to the version number. When
		118	using the @@RXVT_NAME@@c client, the version displayed is that of the
		119	daemon.
		120
		121	=item I am using Debian GNU/Linux and have a problem...
		122
		123	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		124	patches that considerably change the behaviour of rxvt-unicode. Before
		125	reporting a bug to the original rxvt-unicode author please download and
		126	install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
		127	and try to reproduce the problem. If you cannot, chances are that the
		128	problems are specific to Debian GNU/Linux, in which case it should be
		129	reported via the Debian Bug Tracking System (use C<reportbug> to report
		130	the bug).
		131
		132	For other problems that also affect the Debian package, you can and
		133	probably should use the Debian BTS, too, because, after all, it's also a
		134	bug in the Debian version and it serves as a reminder for other users that
		135	might encounter the same issue.
		136
		137	=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		138
		139	You should build one binary with the default options. F<configure>
		140	now enables most useful options, and the trend goes to making them
		141	runtime-switchable, too, so there is usually no drawback to enbaling them,
		142	except higher disk and possibly memory usage. The perl interpreter should
		143	be enabled, as important functionality (menus, selection, likely more in
		144	the future) depends on it.
		145
		146	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		147	system-wide (except maybe with C<defaults>). This will result in useful
		148	behaviour. If your distribution aims at low memory, add an empty
		149	C<perl-ext-common> resource to the app-defaults file. This will keep the
		150	perl interpreter disabled until the user enables it.
		151
		152	If you can/want build more binaries, I recommend building a minimal
		153	one with C<--disable-everything> (very useful) and a maximal one with
		154	C<--enable-everything> (less useful, it will be very big due to a lot of
		155	encodings built-in that increase download times and are rarely used).
		156
		157	=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		158
		159	Likely not. While I honestly try to make it secure, and am probably not
		160	bad at it, I think it is simply unreasonable to expect all of freetype
		161	+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
		162	secure. Also, rxvt-unicode disables some options when it detects that it
		163	runs setuid or setgid, which is not nice. Besides, with the embedded perl
		164	interpreter the possibility for security problems easily multiplies.
		165
		166	Elevated privileges are only required for utmp and pty operations on some
		167	systems (for example, GNU/Linux doesn't need any extra privileges for
		168	ptys, but some need it for utmp support). It is planned to mvoe this into
		169	a forked handler process, but this is not yet done.
		170
		171	So, while setuid/setgid operation is supported and not a problem on your
		172	typical single-user-no-other-logins unix desktop, always remember that
		173	its an awful lot of code, most of which isn't checked for security issues
		174	regularly.
		175
		176	=item When I log-in to another system it tells me about missing terminfo data?
		177
		178	The terminal description used by rxvt-unicode is not as widely available
		179	as that for xterm, or even rxvt (for which the same problem often arises).
		180
		181	The correct solution for this problem is to install the terminfo, this can
		182	be done like this (with ncurses' infocmp):
		183
		184	REMOTE=remotesystem.domain
		185	infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
		186
		187	... or by installing rxvt-unicode normally on the remote system,
		188
		189	If you cannot or do not want to do this, then you can simply set
		190	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		191	problems arising, which includes wrong keymapping, less and different
		192	colours and some refresh errors in fullscreen applications. It's a nice
		193	quick-and-dirty workaround for rare cases, though.
		194
		195	If you always want to do this (and are fine with the consequences) you
		196	can either recompile rxvt-unicode with the desired TERM value or use a
		197	resource to set it:
		198
		199	URxvt.termName: rxvt
		200
		201	If you don't plan to use B<rxvt> (quite common...) you could also replace
		202	the rxvt terminfo file with the rxvt-unicode one.
		203
		204	=item C<tic> outputs some error when compiling the terminfo entry.
		205
		206	Most likely it's the empty definition for C<enacs=>. Just replace it by
		207	C<enacs=\E[0@> and try again.
		208
		209	=item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
		210
		211	=item I need a termcap file entry.
		212
		213	One reason you might want this is that some distributions or operating
		214	systems still compile some programs using the long-obsoleted termcap
		215	library (Fedora Core's bash is one example) and rely on a termcap entry
		216	for C<rxvt-unicode>.
		217
		218	You could use rxvt's termcap entry with resonable results in many cases.
		219	You can also create a termcap entry by using terminfo's infocmp program
		220	like this:
		221
		222	infocmp -C rxvt-unicode
		223
		224	Or you could use this termcap entry, generated by the command above:
		225

		246
		247	=item Why does C<ls> no longer have coloured output?
		248
		249	The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
		250	decide wether a terminal has colour, but uses it's own configuration
		251	file. Needless to say, C<rxvt-unicode> is not in it's default file (among
		252	with most other terminals supporting colour). Either add:
		253
		254	TERM rxvt-unicode
		255
		256	to C</etc/DIR_COLORS> or simply add:
		257
		258	alias ls='ls --color=auto'
		259
		260	to your C<.profile> or C<.bashrc>.
		261
		262	=item Why doesn't vim/emacs etc. use the 88 colour mode?
		263
		264	=item Why doesn't vim/emacs etc. make use of italic?
		265
		266	=item Why are the secondary screen-related options not working properly?
		267
		268	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		269	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		270	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		271	features. Unfortunately, some of these (most notably, again, Debian
		272	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		273	file, so you will need to install it on your own (See the question B<When
		274	I log-in to another system it tells me about missing terminfo data?> on
		275	how to do this).
		276
		277	=item My numerical keypad acts weird and generates differing output?
		278
		279	Some Debian GNUL/Linux users seem to have this problem, although no
		280	specific details were reported so far. It is possible that this is caused
		281	by the wrong C<TERM> setting, although the details of wether and how
		282	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		283	keymap. See the answer to the previous question, and please report if that
		284	helped.
		285
		286	=item Rxvt-unicode does not seem to understand the selected encoding?
		287
		288	=item Unicode does not seem to work?
		289
		290	If you encounter strange problems like typing an accented character but
		291	getting two unrelated other characters or similar, or if program output is
		292	subtly garbled, then you should check your locale settings.
		293
		294	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		295	programs. Often rxvt-unicode is started in the C<C> locale, while the
		296	login script running within the rxvt-unicode window changes the locale to
		297	something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
		298
		299	The best thing is to fix your startup environment, as you will likely run
		300	into other problems. If nothing works you can try this in your .profile.
		301
		302	printf '\e]701;%s\007' "$LC_CTYPE"
		303
		304	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		305	supported on your systems. Some systems have a C<locale> command which
		306	displays this (also, C<perl -e0> can be used to check locale settings, as
		307	it will complain loudly if it cannot set the locale). If it displays something
		308	like:
		309
		310	locale: Cannot set LC_CTYPE to default locale: ...
		311
		312	Then the locale you specified is not supported on your system.
		313
		314	If nothing works and you are sure that everything is set correctly then
		315	you will need to remember a little known fact: Some programs just don't
		316	support locales :(
		317
		318	=item Why do some characters look so much different than others?
		319
		320	=item How does rxvt-unicode choose fonts?
		321
		322	Most fonts do not contain the full range of Unicode, which is
		323	fine. Chances are that the font you (or the admin/package maintainer of
		324	your system/os) have specified does not cover all the characters you want
		325	to display.
		326
		327	B<rxvt-unicode> makes a best-effort try at finding a replacement
		328	font. Often the result is fine, but sometimes the chosen font looks
		329	bad/ugly/wrong. Some fonts have totally strange characters that don't
		330	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		331	intelligence to detect that a specific glyph is wrong: it has to believe
		332	the font that the characters it claims to contain indeed look correct.
		333
		334	In that case, select a font of your taste and add it to the font list,
		335	e.g.:
		336
		337	@@RXVT_NAME@@ -fn basefont,font2,font3...
		338
		339	When rxvt-unicode sees a character, it will first look at the base
		340	font. If the base font does not contain the character, it will go to the
		341	next font, and so on. Specifying your own fonts will also speed up this
		342	search and use less resources within rxvt-unicode and the X-server.
		343
		344	The only limitation is that none of the fonts may be larger than the base
		345	font, as the base font defines the terminal character cell size, which
		346	must be the same due to the way terminals work.
		347
		348	=item Why do some chinese characters look so different than others?
		349
		350	This is because there is a difference between script and language --
		351	rxvt-unicode does not know which language the text that is output is,
		352	as it only knows the unicode character codes. If rxvt-unicode first
		353	sees a japanese/chinese character, it might choose a japanese font for
		354	display. Subsequent japanese characters will use that font. Now, many
		355	chinese characters aren't represented in japanese fonts, so when the first
		356	non-japanese character comes up, rxvt-unicode will look for a chinese font
		357	-- unfortunately at this point, it will still use the japanese font for
		358	chinese characters that are also in the japanese font.
		359
		360	The workaround is easy: just tag a chinese font at the end of your font
		361	list (see the previous question). The key is to view the font list as
		362	a preference list: If you expect more japanese, list a japanese font
		363	first. If you expect more chinese, put a chinese font first.
		364
		365	In the future it might be possible to switch language preferences at
		366	runtime (the internal data structure has no problem with using different
		367	fonts for the same character at the same time, but no interface for this
		368	has been designed yet).
		369
		370	Until then, you might get away with switching fonts at runtime (see L<Can
		371	I switch the fonts at runtime?> later in this document).
		372
		373	=item Why does rxvt-unicode sometimes leave pixel droppings?
		374
		375	Most fonts were not designed for terminal use, which means that character
		376	size varies a lot. A font that is otherwise fine for terminal use might
		377	contain some characters that are simply too wide. Rxvt-unicode will avoid
		378	these characters. For characters that are just "a bit" too wide a special
		379	"careful" rendering mode is used that redraws adjacent characters.
		380
		381	All of this requires that fonts do not lie about character sizes,
		382	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		383	box, and rxvt-unicode has no way of detecting this (the correct way is to
		384	ask for the character bounding box, which unfortunately is wrong in these
		385	cases).
		386
		387	It's not clear (to me at least), wether this is a bug in Xft, freetype,
		388	or the respective font. If you encounter this problem you might try using
		389	the C<-lsp> option to give the font more height. If that doesn't work, you
		390	might be forced to use a different font.
		391
		392	All of this is not a problem when using X11 core fonts, as their bounding
		393	box data is correct.
		394
		395	=item On Solaris 9, many line-drawing characters are too wide.
		396
		397	Seems to be a known bug, read
		398	L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
		399	following ugly workaround to get non-double-wide-characters working:
		400
		401	#define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
		402
		403	=item My Compose (Multi_key) key is no longer working.
		404
		405	The most common causes for this are that either your locale is not set
		406	correctly, or you specified a B<preeditStyle> that is not supported by
		407	your input method. For example, if you specified B<OverTheSpot> and
		408	your input method (e.g. the default input method handling Compose keys)
		409	does not support this (for instance because it is not visual), then
		410	rxvt-unicode will continue without an input method.
		411
		412	In this case either do not specify a B<preeditStyle> or specify more than
		413	one pre-edit style, such as B<OverTheSpot,Root,None>.
		414
		415	=item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		416
		417	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		418	international keyboards) or simply use ISO 14755 support to your
		419	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		420	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		421	character and so on.
		422
		423	=item How can I keep rxvt-unicode from using reverse video so much?
		424
		425	First of all, make sure you are running with the right terminal settings
		426	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		427	make sure you have specified colours for italic and bold, as otherwise
		428	rxvt-unicode might use reverse video to simulate the effect:
		429
		430	URxvt.colorBD: white
		431	URxvt.colorIT: green
		432
		433	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
		434
		435	For some unexplainable reason, some rare programs assume a very weird
		436	colour palette when confronted with a terminal with more than the standard
		437	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		438	these programs not to assume non-ISO colours without very good reasons.
		439
		440	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		441	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		442	fix colours but keep you from using other rxvt-unicode features.
		443
		444	=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
		445
		446	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
		447	in your compile environment, or an implementation that implements it,
		448	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
		449	B<wchar_t> is represented as unicode.
		450
		451	As you might have guessed, FreeBSD does neither define this symobl nor
		452	does it support it. Instead, it uses it's own internal representation of
		453	B<wchar_t>. This is, of course, completely fine with respect to standards.
		454
		455	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		456	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
		457
		458	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		459	apps in an OS, as using a locale-dependent (and non-standardized)
		460	representation of B<wchar_t> makes it impossible to convert between
		461	B<wchar_t> (as used by X11 and your applications) and any other encoding
		462	without implementing OS-specific-wrappers for each and every locale. There
		463	simply are no APIs to convert B<wchar_t> into anything except the current
		464	locale encoding.
		465
		466	Some applications (such as the formidable B<mlterm>) work around this
		467	by carrying their own replacement functions for character set handling
		468	with them, and either implementing OS-dependent hacks or doing multiple
		469	conversions (which is slow and unreliable in case the OS implements
		470	encodings slightly different than the terminal emulator).
		471
		472	The rxvt-unicode author insists that the right way to fix this is in the
		473	system libraries once and for all, instead of forcing every app to carry
		474	complete replacements for them :)
		475
		476	=item I use Solaris 9 and it doesn't compile/work/etc.
		477
		478	Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
		479	problems with C<wcwidth> and a compile problem.
		480
		481	=item How can I use rxvt-unicode under cygwin?
		482
		483	rxvt-unicode should compile and run out of the box on cygwin, using
		484	the X11 libraries that come with cygwin. libW11 emulation is no
		485	longer supported (and makes no sense, either, as it only supported a
		486	single font). I recommend starting the X-server in C<-multiwindow> or
		487	C<-rootless> mode instead, which will result in similar look&feel as the
		488	old libW11 emulation.
		489
		490	At the time of this writing, cygwin didn't seem to support any multi-byte
		491	encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
		492	to 8-bit encodings.
		493
		494	=item How does rxvt-unicode determine the encoding to use?
		495
		496	=item Is there an option to switch encodings?
		497
		498	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		499	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		500	UTF-8 or any other encodings with respect to terminal I/O.
		501
		502	The reasons is that there exists a perfectly fine mechanism for selecting
		503	the encoding, doing I/O and (most important) communicating this to all
		504	applications so everybody agrees on character properties such as width
		505	and code number. This mechanism is the I<locale>. Applications not using
		506	that info will have problems (for example, C<xterm> gets the width of
		507	characters wrong as it uses it's own, locale-independent table under all
		508	locales).
		509
		510	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		511	programs doing the same (that is, most) will automatically agree in the
		512	interpretation of characters.
		513
		514	Unfortunately, there is no system-independent way to select locales, nor
		515	is there a standard on how locale specifiers will look like.
		516
		517	On most systems, the content of the C<LC_CTYPE> environment variable
		518	contains an arbitrary string which corresponds to an already-installed
		519	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		520	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		521	(i.e. C<de> or C<german>) are also common.
		522
		523	Rxvt-unicode ignores all other locale categories, and except for
		524	the encoding, ignores country or language-specific settings,
		525	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		526	rxvt-unicode.
		527
		528	If you want to use a specific encoding you have to make sure you start
		529	rxvt-unicode with the correct C<LC_CTYPE> category.
		530
		531	=item Can I switch locales at runtime?
		532
		533	Yes, using an escape sequence. Try something like this, which sets
		534	rxvt-unicode's idea of C<LC_CTYPE>.
		535
		536	printf '\e]701;%s\007' ja_JP.SJIS
		537
		538	See also the previous answer.
		539
		540	Sometimes this capability is rather handy when you want to work in
		541	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		542	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		543	first switches to a locale supported by xjdic and back later:
		544
		545	printf '\e]701;%s\007' ja_JP.SJIS
		546	xjdic -js
		547	printf '\e]701;%s\007' de_DE.UTF-8
		548
		549	You can also use xterm's C<luit> program, which usually works fine, except
		550	for some locales where character width differs between program- and
		551	rxvt-unicode-locales.
		552
		553	=item Can I switch the fonts at runtime?
		554
		555	Yes, using an escape sequence. Try something like this, which has the same
		556	effect as using the C<-fn> switch, and takes effect immediately:
		557
		558	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
		559
		560	This is useful if you e.g. work primarily with japanese (and prefer a
		561	japanese font), but you have to switch to chinese temporarily, where
		562	japanese fonts would only be in your way.
		563
		564	You can think of this as a kind of manual ISO-2022 switching.
		565
		566	=item Why do italic characters look as if clipped?
		567
		568	Many fonts have difficulties with italic characters and hinting. For
		569	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		570	Mono> completely fails in it's italic face. A workaround might be to
		571	enable freetype autohinting, i.e. like this:
		572
		573	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		574	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		575
		576	=item My input method wants <some encoding> but I want UTF-8, what can I do?
		577
		578	You can specify separate locales for the input method and the rest of the
		579	terminal, using the resource C<imlocale>:
		580
		581	URxvt*imlocale: ja_JP.EUC-JP
		582
		583	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		584	use your input method. Please note, however, that you will not be able to
		585	input characters outside C<EUC-JP> in a normal way then, as your input
		586	method limits you.
		587
		588	=item Rxvt-unicode crashes when the X Input Method changes or exits.
		589
		590	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		591	design. Applications can avoid some crashes at the expense of memory
		592	leaks, and Input Methods can avoid some crashes by careful ordering at
		593	exit time. B<kinput2> (and derived input methods) generally succeeds,
		594	while B<SCIM> (or similar input methods) fails. In the end, however,
		595	crashes cannot be completely avoided even if both sides cooperate.
		596
		597	So the only workaround is not to kill your Input Method Servers.
		598
		599	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
		600
		601	Rxvt-unicode tries to obey the rule of not charging you for something you
		602	don't use. One thing you should try is to configure out all settings that
		603	you don't need, for example, Xft support is a resource hog by design,
		604	when used. Compiling it out ensures that no Xft font will be loaded
		605	accidentally when rxvt-unicode tries to find a font for your characters.
		606
		607	Also, many people (me included) like large windows and even larger
		608	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
		609	6 bytes per screen cell. For a 160x?? window this amounts to almost a
		610	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
		611	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
		612	rxvt-unicode then uses 8 bytes per screen cell.
		613
		614	=item Can I speed up Xft rendering somehow?
		615
		616	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		617	it is simply slow. If you still want Xft fonts you might try to disable
		618	antialiasing (by appending C<:antialias=false>), which saves lots of
		619	memory and also speeds up rendering considerably.
		620
		621	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		622
		623	Rxvt-unicode will use whatever you specify as a font. If it needs to
		624	fall back to it's default font search list it will prefer X11 core
		625	fonts, because they are small and fast, and then use Xft fonts. It has
		626	antialiasing disabled for most of them, because the author thinks they
		627	look best that way.
		628
		629	If you want antialiasing, you have to specify the fonts manually.
		630
		631	=item Mouse cut/paste suddenly no longer works.
		632
		633	Make sure that mouse reporting is actually turned off since killing
		634	some editors prematurely may leave the mouse in mouse report mode. I've
		635	heard that tcsh may use mouse reporting unless it otherwise specified. A
		636	quick check is to see if cut/paste works when the Alt or Shift keys are
		637	depressed. See @@RXVT_NAME@@(7)
		638
		639	=item What's with this bold/blink stuff?
		640
		641	If no bold colour is set via C<colorBD:>, bold will invert text using the
		642	standard foreground colour.
		643
		644	For the standard background colour, blinking will actually make the
		645	text blink when compiled with C<--enable-blinking>. with standard
		646	colours. Without C<--enable-blinking>, the blink attribute will be
		647	ignored.
		648
		649	On ANSI colours, bold/blink attributes are used to set high-intensity
		650	foreground/background colors.
		651
		652	color0-7 are the low-intensity colors.
		653
		654	color8-15 are the corresponding high-intensity colors.
		655
		656	=item I don't like the screen colors. How do I change them?
		657
		658	You can change the screen colors at run-time using F<~/.Xdefaults>
		659	resources (or as long-options).
		660
		661	Here are values that are supposed to resemble a VGA screen,
		662	including the murky brown that passes for low-intensity yellow:
		663
		664	URxvt.color0: #000000

		709	=item What's with the strange Backspace/Delete key behaviour?
		710
		711	Assuming that the physical Backspace key corresponds to the
		712	BackSpace keysym (not likely for Linux ... see the following
		713	question) there are two standard values that can be used for
		714	Backspace: C<^H> and C<^?>.
		715
		716	Historically, either value is correct, but rxvt-unicode adopts the debian
		717	policy of using C<^?> when unsure, because it's the one only only correct
		718	choice :).
		719
		720	Rxvt-unicode tries to inherit the current stty settings and uses the value
		721	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
		722	started from a terminal (say, from a menu or by remote shell), then the
		723	system value of `erase', which corresponds to CERASE in <termios.h>, will
		724	be used (which may not be the same as your stty setting).
		725
		726	For starting a new rxvt-unicode:
		727
		728	# use Backspace = ^H
		729	$ stty erase ^H
		730	$ @@RXVT_NAME@@
		731
		732	# use Backspace = ^?
		733	$ stty erase ^?
		734	$ @@RXVT_NAME@@
		735
		736	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l> as documented in @@RXVT_NAME@@(7).
		737
		738	For an existing rxvt-unicode:
		739
		740	# use Backspace = ^H
		741	$ stty erase ^H
		742	$ echo -n "^[[36h"
		743
		744	# use Backspace = ^?
		745	$ stty erase ^?
		746	$ echo -n "^[[36l"
		747
		748	This helps satisfy some of the Backspace discrepancies that occur, but
		749	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
		750	properly reflects that.
		751
		752	The Delete key is a another casualty of the ill-defined Backspace problem.
		753	To avoid confusion between the Backspace and Delete keys, the Delete
		754	key has been assigned an escape sequence to match the vt100 for Execute
		755	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
		756
		757	Some other Backspace problems:
		758
		759	some editors use termcap/terminfo,
		760	some editors (vim I'm told) expect Backspace = ^H,
		761	GNU Emacs (and Emacs-like editors) use ^H for help.
		762
		763	Perhaps someday this will all be resolved in a consistent manner.
		764
		765	=item I don't like the key-bindings. How do I change them?
		766
		767	There are some compile-time selections available via configure. Unless
