		16	=head1 DESCRIPTION
		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. Before
		165	reporting a bug to the original rxvt-unicode author please download and
		166	install the genuine version (L<http://software.schmorp.de#rxvt-unicode>)
		167	and try to reproduce the problem. If you cannot, chances are that the
		168	problems are specific to Debian GNU/Linux, in which case it should be
		169	reported via the Debian Bug Tracking System (use C<reportbug> to report
		170	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 recommendation?
		178
		179	You should build one binary with the default options. F<configure>
		180	now enables most useful options, and the trend goes to making them
		181	runtime-switchable, too, so there is usually no drawback to enbaling them,
		182	except higher disk and possibly memory usage. The perl interpreter should
		183	be enabled, as important functionality (menus, selection, likely more in
		184	the future) depends on it.
		185
		186	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		187	system-wide (except maybe with C<defaults>). This will result in useful
		188	behaviour. If your distribution aims at low memory, add an empty
		189	C<perl-ext-common> resource to the app-defaults file. This will keep the
		190	perl interpreter disabled until the user enables it.
		191
		192	If you can/want build more binaries, I recommend building a minimal
		193	one with C<--disable-everything> (very useful) and a maximal one with
		194	C<--enable-everything> (less useful, it will be very big due to a lot of
		195	encodings built-in that increase download times and are rarely used).
		196
		197	=item I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		198
		199	Likely not. While I honestly try to make it secure, and am probably not
		200	bad at it, I think it is simply unreasonable to expect all of freetype
		201	+ fontconfig + xft + xlib + perl + ... + rxvt-unicode itself to all be
		202	secure. Also, rxvt-unicode disables some options when it detects that it
		203	runs setuid or setgid, which is not nice. Besides, with the embedded perl
		204	interpreter the possibility for security problems easily multiplies.
		205
		206	Elevated privileges are only required for utmp and pty operations on some
		207	systems (for example, GNU/Linux doesn't need any extra privileges for
		208	ptys, but some need it for utmp support). It is planned to mvoe this into
		209	a forked handler process, but this is not yet done.
		210
		211	So, while setuid/setgid operation is supported and not a problem on your
		212	typical single-user-no-other-logins unix desktop, always remember that
		213	its an awful lot of code, most of which isn't checked for security issues
		214	regularly.
		215
		216	=item When I log-in to another system it tells me about missing terminfo data?
		217
		218	The terminal description used by rxvt-unicode is not as widely available
		219	as that for xterm, or even rxvt (for which the same problem often arises).
		220
		221	The correct solution for this problem is to install the terminfo, this can
		222	be done like this (with ncurses' infocmp):
		223
		224	REMOTE=remotesystem.domain
		225	infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
		226
		227	... or by installing rxvt-unicode normally on the remote system,
		228
		229	If you cannot or do not want to do this, then you can simply set
		230	C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
		231	problems arising, which includes wrong keymapping, less and different
		232	colours and some refresh errors in fullscreen applications. It's a nice
		233	quick-and-dirty workaround for rare cases, though.
		234
		235	If you always want to do this (and are fine with the consequences) you
		236	can either recompile rxvt-unicode with the desired TERM value or use a
		237	resource to set it:
		238
		239	URxvt.termName: rxvt
		240
		241	If you don't plan to use B<rxvt> (quite common...) you could also replace
		242	the rxvt terminfo file with the rxvt-unicode one.
		243
		244	=item C<tic> outputs some error when compiling the terminfo entry.
		245
		246	Most likely it's the empty definition for C<enacs=>. Just replace it by
		247	C<enacs=\E[0@> and try again.
		248
		249	=item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
		250
		251	=item I need a termcap file entry.
		252
		253	One reason you might want this is that some distributions or operating
		254	systems still compile some programs using the long-obsoleted termcap
		255	library (Fedora Core's bash is one example) and rely on a termcap entry
		256	for C<rxvt-unicode>.
		257
		258	You could use rxvt's termcap entry with resonable results in many cases.
		259	You can also create a termcap entry by using terminfo's infocmp program
		260	like this:
		261
		262	infocmp -C rxvt-unicode
		263
		264	Or you could use this termcap entry, generated by the command above:
		265
		266	rxvt-unicode|rxvt-unicode terminal (X Window System):\

		286
		287	=item Why does C<ls> no longer have coloured output?
		288
		289	The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
		290	decide wether a terminal has colour, but uses it's own configuration
		291	file. Needless to say, C<rxvt-unicode> is not in it's default file (among
		292	with most other terminals supporting colour). Either add:
		293
		294	TERM rxvt-unicode
		295
		296	to C</etc/DIR_COLORS> or simply add:
		297
		298	alias ls='ls --color=auto'
		299
		300	to your C<.profile> or C<.bashrc>.
		301
		302	=item Why doesn't vim/emacs etc. use the 88 colour mode?
		303
		304	=item Why doesn't vim/emacs etc. make use of italic?
		305
		306	=item Why are the secondary screen-related options not working properly?
		307
		308	Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
		309	distributions (most notably Debian GNU/Linux) break rxvt-unicode
		310	by setting C<TERM> to C<rxvt>, which doesn't have these extra
		311	features. Unfortunately, some of these (most notably, again, Debian
		312	GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
		313	file, so you will need to install it on your own (See the question B<When
		314	I log-in to another system it tells me about missing terminfo data?> on
		315	how to do this).
		316
		317	=item My numerical keypad acts weird and generates differing output?
		318
		319	Some Debian GNUL/Linux users seem to have this problem, although no
		320	specific details were reported so far. It is possible that this is caused
		321	by the wrong C<TERM> setting, although the details of wether and how
		322	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		323	keymap. See the answer to the previous question, and please report if that
		324	helped.
		325
		326	=item Rxvt-unicode does not seem to understand the selected encoding?
		327
		328	=item Unicode does not seem to work?
		329
		330	If you encounter strange problems like typing an accented character but
		331	getting two unrelated other characters or similar, or if program output is
		332	subtly garbled, then you should check your locale settings.
		333
		334	Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
		335	programs. Often rxvt-unicode is started in the C<C> locale, while the
		336	login script running within the rxvt-unicode window changes the locale to
		337	something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
		338
		339	The best thing is to fix your startup environment, as you will likely run
		340	into other problems. If nothing works you can try this in your .profile.
		341
		342	printf '\e]701;%s\007' "$LC_CTYPE"
		343
		344	If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
		345	supported on your systems. Some systems have a C<locale> command which
		346	displays this (also, C<perl -e0> can be used to check locale settings, as
		347	it will complain loudly if it cannot set the locale). If it displays something
		348	like:
		349
		350	locale: Cannot set LC_CTYPE to default locale: ...
		351
		352	Then the locale you specified is not supported on your system.
		353
		354	If nothing works and you are sure that everything is set correctly then
		355	you will need to remember a little known fact: Some programs just don't
		356	support locales :(
		357
		358	=item Why do some characters look so much different than others?
		359
		360	=item How does rxvt-unicode choose fonts?
		361
		362	Most fonts do not contain the full range of Unicode, which is
		363	fine. Chances are that the font you (or the admin/package maintainer of
		364	your system/os) have specified does not cover all the characters you want
		365	to display.
		366
		367	B<rxvt-unicode> makes a best-effort try at finding a replacement
		368	font. Often the result is fine, but sometimes the chosen font looks
		369	bad/ugly/wrong. Some fonts have totally strange characters that don't
		370	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		371	intelligence to detect that a specific glyph is wrong: it has to believe
		372	the font that the characters it claims to contain indeed look correct.
		373
		374	In that case, select a font of your taste and add it to the font list,
		375	e.g.:
		376
		377	@@RXVT_NAME@@ -fn basefont,font2,font3...
		378
		379	When rxvt-unicode sees a character, it will first look at the base
		380	font. If the base font does not contain the character, it will go to the
		381	next font, and so on. Specifying your own fonts will also speed up this
		382	search and use less resources within rxvt-unicode and the X-server.
		383
		384	The only limitation is that none of the fonts may be larger than the base
		385	font, as the base font defines the terminal character cell size, which
		386	must be the same due to the way terminals work.
		387
		388	=item Why do some chinese characters look so different than others?
		389
		390	This is because there is a difference between script and language --
		391	rxvt-unicode does not know which language the text that is output is,
		392	as it only knows the unicode character codes. If rxvt-unicode first
		393	sees a japanese/chinese character, it might choose a japanese font for
		394	display. Subsequent japanese characters will use that font. Now, many
		395	chinese characters aren't represented in japanese fonts, so when the first
		396	non-japanese character comes up, rxvt-unicode will look for a chinese font
		397	-- unfortunately at this point, it will still use the japanese font for
		398	chinese characters that are also in the japanese font.
		399
		400	The workaround is easy: just tag a chinese font at the end of your font
		401	list (see the previous question). The key is to view the font list as
		402	a preference list: If you expect more japanese, list a japanese font
		403	first. If you expect more chinese, put a chinese font first.
		404
		405	In the future it might be possible to switch language preferences at
		406	runtime (the internal data structure has no problem with using different
		407	fonts for the same character at the same time, but no interface for this
		408	has been designed yet).
		409
		410	Until then, you might get away with switching fonts at runtime (see L<Can
		411	I switch the fonts at runtime?> later in this document).
		412
		413	=item Why does rxvt-unicode sometimes leave pixel droppings?
		414
		415	Most fonts were not designed for terminal use, which means that character
		416	size varies a lot. A font that is otherwise fine for terminal use might
		417	contain some characters that are simply too wide. Rxvt-unicode will avoid
		418	these characters. For characters that are just "a bit" too wide a special
		419	"careful" rendering mode is used that redraws adjacent characters.
		420
		421	All of this requires that fonts do not lie about character sizes,
		422	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		423	box, and rxvt-unicode has no way of detecting this (the correct way is to
		424	ask for the character bounding box, which unfortunately is wrong in these
		425	cases).
		426
		427	It's not clear (to me at least), wether this is a bug in Xft, freetype,
		428	or the respective font. If you encounter this problem you might try using
		429	the C<-lsp> option to give the font more height. If that doesn't work, you
		430	might be forced to use a different font.
		431
		432	All of this is not a problem when using X11 core fonts, as their bounding
		433	box data is correct.
		434
		435	=item On Solaris 9, many line-drawing characters are too wide.
		436
		437	Seems to be a known bug, read
		438	L<http://nixdoc.net/files/forum/about34198.html>. Some people use the
		439	following ugly workaround to get non-double-wide-characters working:
		440
		441	#define wcwidth(x) wcwidth(x) > 1 ? 1 : wcwidth(x)
		442
		443	=item My Compose (Multi_key) key is no longer working.
		444
		445	The most common causes for this are that either your locale is not set
		446	correctly, or you specified a B<preeditStyle> that is not supported by
		447	your input method. For example, if you specified B<OverTheSpot> and
		448	your input method (e.g. the default input method handling Compose keys)
		449	does not support this (for instance because it is not visual), then
		450	rxvt-unicode will continue without an input method.
		451
		452	In this case either do not specify a B<preeditStyle> or specify more than
		453	one pre-edit style, such as B<OverTheSpot,Root,None>.
		454
		455	=item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
		456
		457	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
		458	international keyboards) or simply use ISO 14755 support to your
		459	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
		460	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
		461	character and so on.
		462
		463	=item How can I keep rxvt-unicode from using reverse video so much?
		464
		465	First of all, make sure you are running with the right terminal settings
		466	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		467	make sure you have specified colours for italic and bold, as otherwise
		468	rxvt-unicode might use reverse video to simulate the effect:
		469
		470	URxvt.colorBD: white
		471	URxvt.colorIT: green
		472
		473	=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
		474
		475	For some unexplainable reason, some rare programs assume a very weird
		476	colour palette when confronted with a terminal with more than the standard
		477	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		478	these programs not to assume non-ISO colours without very good reasons.
		479
		480	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		481	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		482	fix colours but keep you from using other rxvt-unicode features.
		483
		484	=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
		485
		486	Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
		487	in your compile environment, or an implementation that implements it,
		488	wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
		489	B<wchar_t> is represented as unicode.
		490
		491	As you might have guessed, FreeBSD does neither define this symobl nor
		492	does it support it. Instead, it uses it's own internal representation of
		493	B<wchar_t>. This is, of course, completely fine with respect to standards.
		494
		495	However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
		496	C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
		497
		498	C<__STDC_ISO_10646__> is the only sane way to support multi-language
		499	apps in an OS, as using a locale-dependent (and non-standardized)
		500	representation of B<wchar_t> makes it impossible to convert between
		501	B<wchar_t> (as used by X11 and your applications) and any other encoding
		502	without implementing OS-specific-wrappers for each and every locale. There
		503	simply are no APIs to convert B<wchar_t> into anything except the current
		504	locale encoding.
		505
		506	Some applications (such as the formidable B<mlterm>) work around this
		507	by carrying their own replacement functions for character set handling
		508	with them, and either implementing OS-dependent hacks or doing multiple
		509	conversions (which is slow and unreliable in case the OS implements
		510	encodings slightly different than the terminal emulator).
		511
		512	The rxvt-unicode author insists that the right way to fix this is in the
		513	system libraries once and for all, instead of forcing every app to carry
		514	complete replacements for them :)
		515
		516	=item I use Solaris 9 and it doesn't compile/work/etc.
		517
		518	Try the diff in F<doc/solaris9.patch> as a base. It fixes the worst
		519	problems with C<wcwidth> and a compile problem.
		520
		521	=item How can I use rxvt-unicode under cygwin?
		522
		523	rxvt-unicode should compile and run out of the box on cygwin, using
		524	the X11 libraries that come with cygwin. libW11 emulation is no
		525	longer supported (and makes no sense, either, as it only supported a
		526	single font). I recommend starting the X-server in C<-multiwindow> or
		527	C<-rootless> mode instead, which will result in similar look&feel as the
		528	old libW11 emulation.
		529
		530	At the time of this writing, cygwin didn't seem to support any multi-byte
		531	encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
		532	to 8-bit encodings.
		533
		534	=item How does rxvt-unicode determine the encoding to use?
		535
		536	=item Is there an option to switch encodings?
		537
		538	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
		539	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
		540	UTF-8 or any other encodings with respect to terminal I/O.
		541
		542	The reasons is that there exists a perfectly fine mechanism for selecting
		543	the encoding, doing I/O and (most important) communicating this to all
		544	applications so everybody agrees on character properties such as width
		545	and code number. This mechanism is the I<locale>. Applications not using
		546	that info will have problems (for example, C<xterm> gets the width of
		547	characters wrong as it uses it's own, locale-independent table under all
		548	locales).
		549
		550	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
		551	programs doing the same (that is, most) will automatically agree in the
		552	interpretation of characters.
		553
		554	Unfortunately, there is no system-independent way to select locales, nor
		555	is there a standard on how locale specifiers will look like.
		556
		557	On most systems, the content of the C<LC_CTYPE> environment variable
		558	contains an arbitrary string which corresponds to an already-installed
		559	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		560	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		561	(i.e. C<de> or C<german>) are also common.
		562
		563	Rxvt-unicode ignores all other locale categories, and except for
		564	the encoding, ignores country or language-specific settings,
		565	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		566	rxvt-unicode.
		567
		568	If you want to use a specific encoding you have to make sure you start
		569	rxvt-unicode with the correct C<LC_CTYPE> category.
		570
		571	=item Can I switch locales at runtime?
		572
		573	Yes, using an escape sequence. Try something like this, which sets
		574	rxvt-unicode's idea of C<LC_CTYPE>.
		575
		576	printf '\e]701;%s\007' ja_JP.SJIS
		577
		578	See also the previous answer.
		579
		580	Sometimes this capability is rather handy when you want to work in
		581	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		582	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		583	first switches to a locale supported by xjdic and back later:
		584
		585	printf '\e]701;%s\007' ja_JP.SJIS
		586	xjdic -js
		587	printf '\e]701;%s\007' de_DE.UTF-8
		588
		589	You can also use xterm's C<luit> program, which usually works fine, except
		590	for some locales where character width differs between program- and
		591	rxvt-unicode-locales.
		592
		593	=item Can I switch the fonts at runtime?
		594
		595	Yes, using an escape sequence. Try something like this, which has the same
		596	effect as using the C<-fn> switch, and takes effect immediately:
		597
		598	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
		599
		600	This is useful if you e.g. work primarily with japanese (and prefer a
		601	japanese font), but you have to switch to chinese temporarily, where
		602	japanese fonts would only be in your way.
		603
		604	You can think of this as a kind of manual ISO-2022 switching.
		605
		606	=item Why do italic characters look as if clipped?
		607
		608	Many fonts have difficulties with italic characters and hinting. For
		609	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		610	Mono> completely fails in it's italic face. A workaround might be to
		611	enable freetype autohinting, i.e. like this:
		612
		613	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		614	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		615
		616	=item My input method wants <some encoding> but I want UTF-8, what can I do?
		617
		618	You can specify separate locales for the input method and the rest of the
		619	terminal, using the resource C<imlocale>:
		620
		621	URxvt*imlocale: ja_JP.EUC-JP
		622
		623	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		624	use your input method. Please note, however, that you will not be able to
		625	input characters outside C<EUC-JP> in a normal way then, as your input
		626	method limits you.
		627
		628	=item Rxvt-unicode crashes when the X Input Method changes or exits.
		629
		630	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		631	design. Applications can avoid some crashes at the expense of memory
		632	leaks, and Input Methods can avoid some crashes by careful ordering at
		633	exit time. B<kinput2> (and derived input methods) generally succeeds,
		634	while B<SCIM> (or similar input methods) fails. In the end, however,
		635	crashes cannot be completely avoided even if both sides cooperate.
		636
		637	So the only workaround is not to kill your Input Method Servers.
		638
		639	=item Rxvt-unicode uses gobs of memory, how can I reduce that?
		640
		641	Rxvt-unicode tries to obey the rule of not charging you for something you
		642	don't use. One thing you should try is to configure out all settings that
		643	you don't need, for example, Xft support is a resource hog by design,
		644	when used. Compiling it out ensures that no Xft font will be loaded
		645	accidentally when rxvt-unicode tries to find a font for your characters.
		646
		647	Also, many people (me included) like large windows and even larger
		648	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
		649	6 bytes per screen cell. For a 160x?? window this amounts to almost a
		650	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
		651	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
		652	rxvt-unicode then uses 8 bytes per screen cell.
		653
		654	=item Can I speed up Xft rendering somehow?
		655
		656	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		657	it is simply slow. If you still want Xft fonts you might try to disable
		658	antialiasing (by appending C<:antialias=false>), which saves lots of
		659	memory and also speeds up rendering considerably.
		660
		661	=item Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		662
		663	Rxvt-unicode will use whatever you specify as a font. If it needs to
		664	fall back to it's default font search list it will prefer X11 core
		665	fonts, because they are small and fast, and then use Xft fonts. It has
		666	antialiasing disabled for most of them, because the author thinks they
		667	look best that way.
		668
		669	If you want antialiasing, you have to specify the fonts manually.
		670
		671	=item Mouse cut/paste suddenly no longer works.
		672
		673	Make sure that mouse reporting is actually turned off since killing
		674	some editors prematurely may leave the mouse in mouse report mode. I've
		675	heard that tcsh may use mouse reporting unless it otherwise specified. A
		676	quick check is to see if cut/paste works when the Alt or Shift keys are
		677	depressed.
		678
		679	=item What's with this bold/blink stuff?
		680
		681	If no bold colour is set via C<colorBD:>, bold will invert text using the
		682	standard foreground colour.
		683
		684	For the standard background colour, blinking will actually make the
		685	text blink when compiled with C<--enable-blinking>. with standard
		686	colours. Without C<--enable-blinking>, the blink attribute will be
		687	ignored.
		688
		689	On ANSI colours, bold/blink attributes are used to set high-intensity
		690	foreground/background colors.
		691
		692	color0-7 are the low-intensity colors.
		693
		694	color8-15 are the corresponding high-intensity colors.
		695
		696	=item I don't like the screen colors. How do I change them?
		697
		698	You can change the screen colors at run-time using F<~/.Xdefaults>
		699	resources (or as long-options).
		700
		701	Here are values that are supposed to resemble a VGA screen,
		702	including the murky brown that passes for low-intensity yellow:

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

		803	Perhaps someday this will all be resolved in a consistent manner.

		837	How do I make use of them? For example, the Sun Keyboard type 4
		838	has the following mappings that rxvt-unicode doesn't recognize.
		839
		840	KP_Insert == Insert
		841	F22 == Print
		842	F27 == Home
		843	F29 == Prior
		844	F33 == End
		845	F35 == Next
		846
		847	Rather than have rxvt-unicode try to accommodate all the various possible
		848	keyboard mappings, it is better to use `xmodmap' to remap the keys as
		849	required for your particular machine.
		850
		851	=item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
		852	I need this to decide about setting colors etc.
		853
		854	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
		855	check and see if that is set. Note that several programs, JED, slrn,
		856	Midnight Commander automatically check this variable to decide whether or
		857	not to use color.
		858
		859	=item How do I set the correct, full IP address for the DISPLAY variable?
		860
		861	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
		862	insecure mode then it is possible to use the following shell script
		863	snippets to correctly set the display. If your version of rxvt-unicode
		864	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
		865	the COLORTERM variable can be used to distinguish rxvt-unicode from a
		866	regular xterm.
		867
		868	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
		869	snippets:
		870
		871	# Bourne/Korn/POSIX family of shells:
		872	[ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
		873	if [ ${TERM:-foo} = xterm ]; then
		874	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
		875	echo -n '^[Z'
		876	read term_id
		877	stty icanon echo
		878	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
		879	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
		880	read DISPLAY # set it in our local shell
		881	fi

		883
		884	=item How do I compile the manual pages for myself?
		885
		886	You need to have a recent version of perl installed as F</usr/bin/perl>,
		887	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
		888	the doc subdirectory and enter C<make alldoc>.

		2366
		2367	General hint: if you get compile errors, then likely your configuration
		2368	hasn't been tested well. Either try with C<--enable-everything> or use
		2369	the F<./reconf> script as a base for experiments. F<./reconf> is used by
		2370	myself, so it should generally be a working config. Of course, you should
		2371	always report when a combination doesn't work, so it can be fixed. Marc
		2372	Lehmann <rxvt@schmorp.de>.

		2374	All
		2375
		2376	=over 4
		2377
		2378	=item --enable-everything
		2379
		2380	Add (or remove) support for all non-multichoice options listed in "./configure
		2381	--help".
		2382
		2383	You can specify this and then disable options you do not like by
		2384	I<following> this with the appropriate C<--disable-...> arguments,
		2385	or you can start with a minimal configuration by specifying
		2386	C<--disable-everything> and than adding just the C<--enable-...> arguments
		2387	you want.
		2388
		2389	=item --enable-xft (default: enabled)
		2390
		2391	Add support for Xft (anti-aliases, among others) fonts. Xft fonts are
		2392	slower and require lots of memory, but as long as you don't use them, you
		2393	don't pay for them.
		2394
		2395	=item --enable-font-styles (default: on)
		2396
		2397	Add support for B<bold>, I<italic> and B<< I<bold italic> >> font
		2398	styles. The fonts can be set manually or automatically.
		2399
		2400	=item --with-codesets=NAME,... (default: all)
		2401
		2402	Compile in support for additional codeset (encoding) groups (C<eu>, C<vn>
		2403	are always compiled in, which includes most 8-bit character sets). These
		2404	codeset tables are used for driving X11 core fonts, they are not required
		2405	for Xft fonts, although having them compiled in lets rxvt-unicode choose
		2406	replacement fonts more intelligently. Compiling them in will make your
		2407	binary bigger (all of together cost about 700kB), but it doesn't increase
		2408	memory usage unless you use a font requiring one of these encodings.

		2418
		2419	=end table
		2420
		2421	=item --enable-xim (default: on)
		2422
		2423	Add support for XIM (X Input Method) protocol. This allows using
		2424	alternative input methods (e.g. kinput2) and will also correctly
		2425	set up the input for people using dead keys or compose keys.
		2426
		2427	=item --enable-unicode3 (default: off)
		2428
		2429	Enable direct support for displaying unicode codepoints above
		2430	65535 (the basic multilingual page). This increases storage
		2431	requirements per character from 2 to 4 bytes. X11 fonts do not yet
		2432	support these extra characters, but Xft does.
		2433
		2434	Please note that rxvt-unicode can store unicode code points >65535
		2435	even without this flag, but the number of such characters is
		2436	limited to a view thousand (shared with combining characters,
		2437	see next switch), and right now rxvt-unicode cannot display them
		2438	(input/output and cut&paste still work, though).
		2439
		2440	=item --enable-combining (default: on)
		2441
		2442	Enable automatic composition of combining characters into
		2443	composite characters. This is required for proper viewing of text
		2444	where accents are encoded as seperate unicode characters. This is
		2445	done by using precomposited characters when available or creating
		2446	new pseudo-characters when no precomposed form exists.
		2447
		2448	Without --enable-unicode3, the number of additional precomposed characters
		2449	is rather limited (2048, if this is full, rxvt-unicode will use the
		2450	private use area, extending the number of combinations to 8448). With
		2451	--enable-unicode3, no practical limit exists.
		2452
		2453	This option will also enable storage (but not display) of characters
		2454	beyond plane 0 (>65535) when --enable-unicode3 was not specified.
		2455
		2456	The combining table also contains entries for arabic presentation forms,
		2457	but these are not currently used. Bug me if you want these to be used (and
		2458	tell me how these are to be used...).
		2459
		2460	=item --enable-fallback(=CLASS) (default: Rxvt)
		2461
		2462	When reading resource settings, also read settings for class CLASS. To disable resource fallback use --disable-fallback.
		2463
		2464	=item --with-res-name=NAME (default: urxvt)
		2465
		2466	Use the given name as default application name when
		2467	reading resources. Specify --with-res-name=rxvt to replace rxvt.
		2468
		2469	=item --with-res-class=CLASS /default: URxvt)
		2470
		2471	Use the given class as default application class
		2472	when reading resources. Specify --with-res-class=Rxvt to replace
		2473	rxvt.
		2474
		2475	=item --enable-utmp (default: on)
		2476
		2477	Write user and tty to utmp file (used by programs like F<w>) at
		2478	start of rxvt execution and delete information when rxvt exits.
		2479
		2480	=item --enable-wtmp (default: on)
		2481
		2482	Write user and tty to wtmp file (used by programs like F<last>) at
		2483	start of rxvt execution and write logout when rxvt exits. This
		2484	option requires --enable-utmp to also be specified.
		2485
		2486	=item --enable-lastlog (default: on)
		2487
		2488	Write user and tty to lastlog file (used by programs like
		2489	F<lastlogin>) at start of rxvt execution. This option requires
		2490	--enable-utmp to also be specified.
		2491
		2492	=item --enable-xpm-background (default: on)
		2493
		2494	Add support for XPM background pixmaps.
		2495
		2496	=item --enable-transparency (default: on)
		2497
		2498	Add support for inheriting parent backgrounds thus giving a fake
		2499	transparency to the term.
		2500
		2501	=item --enable-fading (default: on)
		2502
		2503	Add support for fading the text when focus is lost (requires C<--enable-transparency>).
		2504
		2505	=item --enable-tinting (default: on)
		2506
		2507	Add support for tinting of transparent backgrounds (requires C<--enable-transparency>).
		2508
		2509	=item --enable-menubar (default: off) [DEPRECATED]
		2510
		2511	Add support for our menu bar system (this interacts badly with dynamic
		2512	locale switching currently). This option is DEPRECATED and will be removed
		2513	in the future.
		2514
		2515	=item --enable-rxvt-scroll (default: on)
		2516
		2517	Add support for the original rxvt scrollbar.
		2518
		2519	=item --enable-next-scroll (default: on)
		2520
		2521	Add support for a NeXT-like scrollbar.
		2522
		2523	=item --enable-xterm-scroll (default: on)
		2524
		2525	Add support for an Xterm-like scrollbar.
		2526
		2527	=item --enable-plain-scroll (default: on)
		2528
		2529	Add support for a very unobtrusive, plain-looking scrollbar that
		2530	is the favourite of the rxvt-unicode author, having used it for
		2531	many years.
		2532
		2533	=item --enable-half-shadow (default: off)
		2534
		2535	Make shadows on the scrollbar only half the normal width & height.
		2536	only applicable to rxvt scrollbars.
		2537
		2538	=item --enable-ttygid (default: off)
		2539
		2540	Change tty device setting to group "tty" - only use this if
		2541	your system uses this type of security.
		2542
		2543	=item --disable-backspace-key
		2544
		2545	Removes any handling of the backspace key by us - let the X server do it.
		2546
		2547	=item --disable-delete-key
		2548
		2549	Removes any handling of the delete key by us - let the X server
		2550	do it.
		2551
		2552	=item --disable-resources
		2553
		2554	Removes any support for resource checking.
		2555
		2556	=item --disable-swapscreen
		2557
		2558	Remove support for secondary/swap screen.
		2559
		2560	=item --enable-frills (default: on)
		2561
		2562	Add support for many small features that are not essential but nice to
		2563	have. Normally you want this, but for very small binaries you may want to
		2564	disable this.
		2565
		2566	A non-exhaustive list of features enabled by C<--enable-frills> (possibly
		2567	in combination with other switches) is:
		2568
		2569	MWM-hints
		2570	EWMH-hints (pid, utf8 names) and protocols (ping)
		2571	seperate underline colour (-underlineColor)

		2586
		2587	=item --enable-iso14755 (default: on)
		2588
		2589	Enable extended ISO 14755 support (see @@RXVT_NAME@@(1), or
		2590	F<doc/rxvt.1.txt>). Basic support (section 5.1) is enabled by
		2591	C<--enable-frills>, while support for 5.2, 5.3 and 5.4 is enabled with
		2592	this switch.
		2593
		2594	=item --enable-keepscrolling (default: on)
		2595
		2596	Add support for continual scrolling of the display when you hold

		2602
		2603	=item --enable-slipwheeling (default: on)
		2604
		2605	Add support for continual scrolling (using the mouse wheel as an
		2606	accelerator) while the control key is held down. This option
		2607	requires --enable-mousewheel to also be specified.
		2608
		2609	=item --disable-new-selection
		2610
		2611	Remove support for mouse selection style like that of xterm.
		2612
		2613	=item --enable-dmalloc (default: off)
		2614
		2615	Use Gray Watson's malloc - which is good for debugging See
		2616	http://www.letters.com/dmalloc/ for details If you use either this or the
		2617	next option, you may need to edit src/Makefile after compiling to point
		2618	DINCLUDE and DLIB to the right places.
		2619
		2620	You can only use either this option and the following (should
		2621	you use either) .
		2622
		2623	=item --enable-dlmalloc (default: off)
		2624
		2625	Use Doug Lea's malloc - which is good for a production version
		2626	See L<http://g.oswego.edu/dl/html/malloc.html> for details.
		2627
		2628	=item --enable-smart-resize (default: on)
		2629
		2630	Add smart growth/shrink behaviour when changing font size via hot
		2631	keys. This should keep the window corner which is closest to a corner of
		2632	the screen in a fixed position.
		2633
		2634	=item --enable-pointer-blank (default: on)
		2635
		2636	Add support to have the pointer disappear when typing or inactive.
		2637

		2639
		2640	Enable an embedded perl interpreter. See the B<@@RXVT_NAME@@perl(3)>
		2641	manpage (F<doc/rxvtperl.txt>) for more info on this feature, or the files
		2642	in F<src/perl-ext/> for the extensions that are installed by default. The
		2643	perl interpreter that is used can be specified via the C<PERL> environment
		2644	variable when running configure.
		2645
		2646	=item --with-name=NAME (default: urxvt)
		2647
