		33	interested in learning about new and exciting problems (but not FAQs :).
36		34
37	To get a selection that is very similar to the old code, try this pattern:	35	=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
38		36
39	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)	37	Beginning with version 7.3, there is a perl extension that implements a
		38	simple tabbed terminal. It is installed by default, so any of these should
		39	give you tabs:
40		40
41	Please also note that the I<LeftClick Shift-LeftClik> combination also	41	@@URXVT_NAME@@ -pe tabbed
42	selects words like the old code.
43		42
44	=head2 I don't like the new selection/popups/hotkeys/perl, how do I
45	change/disable it?
46
47	You can disable the perl extension completely by setting the
48	B<perl-ext-common> resource to the empty string, which also keeps
49	rxvt-unicode from initialising perl, saving memory.
50
51	If you only want to disable specific features, you first have to
52	identify which perl extension is responsible. For this, read the section
53	B<PREPACKAGED EXTENSIONS> in the @@RXVT_NAME@@perl(3) manpage. For
54	example, to disable the B<selection-popup> and B<option-popup>, specify
55	this B<perl-ext-common> resource:
56
57	URxvt.perl-ext-common: default,-selection-popup,-option-popup
58
59	This will keep the default extensions, but disable the two popup
60	extensions. Some extensions can also be configured, for example,
61	scrollback search mode is triggered by B<M-s>. You can move it to any
62	other combination either by setting the B<searchable-scrollback> resource:
63
64	URxvt.searchable-scrollback: CM-s
65
66	=head2 The cursor moves when selecting text in the current input line, how
67	do I switch this off?
68
69	=head2 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor
70	outputs strange escape sequences, how do I fix this?
71
72	These are caused by the C<readline> perl extension. Under normal
73	circumstances, it will move your cursor around when you click into the
74	line that contains it. It tries hard not to do this at the wrong moment,
75	but when running a program that doesn't parse cursor movements or in some
76	cases during rlogin sessions, it fails to detect this properly.
77
78	You can permamently switch this feature off by disabling the C<readline>
79	extension:
80
81	URxvt.perl-ext-common: default,-readline	43	URxvt.perl-ext-common: default,tabbed
82		44
83	=head2 Why doesn't rxvt-unicode read my resources?	45	It will also work fine with tabbing functionality of many window managers
		46	or similar tabbing programs, and its embedding-features allow it to be
		47	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
		48	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
		49	(murxvt) terminal as an example embedding application.
84		50
85	Well, why, indeed? It does, in a way very similar to other X	51	=head3 How do I know which rxvt-unicode version I'm using?
86	applications. Most importantly, this means that if you or your OS loads
87	resources into the X display (the right way to do it), rxvt-unicode will
88	ignore any resource files in your home directory. It will only read
89	F<$HOME/.Xdefaults> when no resources are attached to the display.
90		52
91	If you have or use an F<$HOME/.Xresources> file, chances are that	53	The version number is displayed with the usage (-h). Also the escape

		56	daemon.
94		57
95	Also consider the form resources have to use:	58	=head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
96		59
97	URxvt.resource: value	60	Rxvt-unicode tries to obey the rule of not charging you for something you
		61	don't use. One thing you should try is to configure out all settings that
		62	you don't need, for example, Xft support is a resource hog by design,
		63	when used. Compiling it out ensures that no Xft font will be loaded
		64	accidentally when rxvt-unicode tries to find a font for your characters.
98		65
99	If you want to use another form (there are lots of different ways of	66	Also, many people (me included) like large windows and even larger

		69	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
		70	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
		71	rxvt-unicode then uses 8 bytes per screen cell.

227		192

		220	That works. If you think it doesn't, you lack XPM and Perl support, or you

		224
		225	@@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
		226

		230	bugfixes and workarounds for Xft and Xlib to make it work, but that

		234
		235	xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
		236	-set _NET_WM_WINDOW_OPACITY 0xc0000000

		239	by other values to change the degree of opacity. If it doesn't work and
		240	your server crashes, you got to keep the pieces.
		241
		242	=head3 Why do some chinese characters look so different than others?
		243
		244	This is because there is a difference between script and language --
		245	rxvt-unicode does not know which language the text that is output is,
		246	as it only knows the unicode character codes. If rxvt-unicode first
		247	sees a japanese/chinese character, it might choose a japanese font for
		248	display. Subsequent japanese characters will use that font. Now, many
		249	chinese characters aren't represented in japanese fonts, so when the first
		250	non-japanese character comes up, rxvt-unicode will look for a chinese font
		251	-- unfortunately at this point, it will still use the japanese font for
		252	chinese characters that are also in the japanese font.
		253
		254	The workaround is easy: just tag a chinese font at the end of your font
		255	list (see the previous question). The key is to view the font list as
		256	a preference list: If you expect more japanese, list a japanese font
		257	first. If you expect more chinese, put a chinese font first.
		258
		259	In the future it might be possible to switch language preferences at
		260	runtime (the internal data structure has no problem with using different
		261	fonts for the same character at the same time, but no interface for this
		262	has been designed yet).
		263
		264	Until then, you might get away with switching fonts at runtime (see L<Can
		265	I switch the fonts at runtime?> later in this document).
		266
		267	=head3 Why does rxvt-unicode sometimes leave pixel droppings?
		268
		269	Most fonts were not designed for terminal use, which means that character
		270	size varies a lot. A font that is otherwise fine for terminal use might
		271	contain some characters that are simply too wide. Rxvt-unicode will avoid
		272	these characters. For characters that are just "a bit" too wide a special
		273	"careful" rendering mode is used that redraws adjacent characters.
		274
		275	All of this requires that fonts do not lie about character sizes,
		276	however: Xft fonts often draw glyphs larger than their acclaimed bounding
		277	box, and rxvt-unicode has no way of detecting this (the correct way is to
		278	ask for the character bounding box, which unfortunately is wrong in these
		279	cases).
		280
		281	It's not clear (to me at least), wether this is a bug in Xft, freetype,
		282	or the respective font. If you encounter this problem you might try using
		283	the C<-lsp> option to give the font more height. If that doesn't work, you
		284	might be forced to use a different font.
		285
		286	All of this is not a problem when using X11 core fonts, as their bounding
		287	box data is correct.
		288
		289	=head3 How can I keep rxvt-unicode from using reverse video so much?
		290
		291	First of all, make sure you are running with the right terminal settings
		292	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
		293	make sure you have specified colours for italic and bold, as otherwise
		294	rxvt-unicode might use reverse video to simulate the effect:
		295
		296	URxvt.colorBD: white
		297	URxvt.colorIT: green
		298
		299	=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
		300
		301	For some unexplainable reason, some rare programs assume a very weird
		302	colour palette when confronted with a terminal with more than the standard
		303	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
		304	these programs not to assume non-ISO colours without very good reasons.
		305
		306	In the meantime, you can either edit your C<rxvt-unicode> terminfo
		307	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
		308	fix colours but keep you from using other rxvt-unicode features.
		309
		310	=head3 Can I switch the fonts at runtime?
		311
		312	Yes, using an escape sequence. Try something like this, which has the same
		313	effect as using the C<-fn> switch, and takes effect immediately:
		314
		315	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
		316
		317	This is useful if you e.g. work primarily with japanese (and prefer a
		318	japanese font), but you have to switch to chinese temporarily, where
		319	japanese fonts would only be in your way.
		320
		321	You can think of this as a kind of manual ISO-2022 switching.
		322
		323	=head3 Why do italic characters look as if clipped?
		324
		325	Many fonts have difficulties with italic characters and hinting. For
		326	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
		327	Mono> completely fails in it's italic face. A workaround might be to
		328	enable freetype autohinting, i.e. like this:
		329
		330	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
		331	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		332
		333	=head3 Can I speed up Xft rendering somehow?
		334
		335	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
		336	it is simply slow. If you still want Xft fonts you might try to disable
		337	antialiasing (by appending C<:antialias=false>), which saves lots of
		338	memory and also speeds up rendering considerably.
		339
		340	=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
		341
		342	Rxvt-unicode will use whatever you specify as a font. If it needs to
		343	fall back to it's default font search list it will prefer X11 core
		344	fonts, because they are small and fast, and then use Xft fonts. It has
		345	antialiasing disabled for most of them, because the author thinks they
		346	look best that way.
		347
		348	If you want antialiasing, you have to specify the fonts manually.
		349
		350	=head3 What's with this bold/blink stuff?
		351
		352	If no bold colour is set via C<colorBD:>, bold will invert text using the
		353	standard foreground colour.
		354
		355	For the standard background colour, blinking will actually make the
		356	text blink when compiled with C<--enable-blinking>. with standard
		357	colours. Without C<--enable-blinking>, the blink attribute will be
		358	ignored.
		359
		360	On ANSI colours, bold/blink attributes are used to set high-intensity
		361	foreground/background colors.
		362
		363	color0-7 are the low-intensity colors.
		364
		365	color8-15 are the corresponding high-intensity colors.
		366
		367	=head3 I don't like the screen colors. How do I change them?
		368
		369	You can change the screen colors at run-time using F<~/.Xdefaults>
		370	resources (or as long-options).
		371
		372	Here are values that are supposed to resemble a VGA screen,
		373	including the murky brown that passes for low-intensity yellow:
		374
		375	URxvt.color0: #000000
		376	URxvt.color1: #A80000
		377	URxvt.color2: #00A800

		379	URxvt.color4: #0000A8
		380	URxvt.color5: #A800A8
		381	URxvt.color6: #00A8A8
		382	URxvt.color7: #A8A8A8
		383
		384	URxvt.color8: #000054
		385	URxvt.color9: #FF0054
		386	URxvt.color10: #00FF54
		387	URxvt.color11: #FFFF54
		388	URxvt.color12: #0000FF
		389	URxvt.color13: #FF00FF
		390	URxvt.color14: #00FFFF
		391	URxvt.color15: #FFFFFF
		392

		394	me) as "pretty girly".

		414
		415	=head3 Why do some characters look so much different than others?
		416
		417	See next entry.
		418
		419	=head3 How does rxvt-unicode choose fonts?
		420
		421	Most fonts do not contain the full range of Unicode, which is
		422	fine. Chances are that the font you (or the admin/package maintainer of
		423	your system/os) have specified does not cover all the characters you want
		424	to display.
		425
		426	B<rxvt-unicode> makes a best-effort try at finding a replacement
		427	font. Often the result is fine, but sometimes the chosen font looks
		428	bad/ugly/wrong. Some fonts have totally strange characters that don't
		429	resemble the correct glyph at all, and rxvt-unicode lacks the artificial
		430	intelligence to detect that a specific glyph is wrong: it has to believe
		431	the font that the characters it claims to contain indeed look correct.
		432
		433	In that case, select a font of your taste and add it to the font list,
		434	e.g.:
		435
		436	@@URXVT_NAME@@ -fn basefont,font2,font3...
		437
		438	When rxvt-unicode sees a character, it will first look at the base
		439	font. If the base font does not contain the character, it will go to the
		440	next font, and so on. Specifying your own fonts will also speed up this
		441	search and use less resources within rxvt-unicode and the X-server.
		442
		443	The only limitation is that none of the fonts may be larger than the base
		444	font, as the base font defines the terminal character cell size, which
		445	must be the same due to the way terminals work.
		446
		447
		448	=head2 Keyboard, Mouse & User Interaction
		449
		450	=head3 The new selection selects pieces that are too big, how can I select single words?
		451
		452	If you want to select e.g. alphanumeric words, you can use the following
		453	setting:
		454
		455	URxvt.selection.pattern-0: ([[:word:]]+)
		456
		457	If you click more than twice, the selection will be extended
		458	more and more.
		459
		460	To get a selection that is very similar to the old code, try this pattern:
		461
		462	URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
		463
		464	Please also note that the I<LeftClick Shift-LeftClik> combination also
		465	selects words like the old code.
		466
		467	=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
		468
		469	You can disable the perl extension completely by setting the
		470	B<perl-ext-common> resource to the empty string, which also keeps
		471	rxvt-unicode from initialising perl, saving memory.
		472
		473	If you only want to disable specific features, you first have to
		474	identify which perl extension is responsible. For this, read the section
		475	B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
		476	example, to disable the B<selection-popup> and B<option-popup>, specify
		477	this B<perl-ext-common> resource:
		478
		479	URxvt.perl-ext-common: default,-selection-popup,-option-popup
		480
		481	This will keep the default extensions, but disable the two popup
		482	extensions. Some extensions can also be configured, for example,
		483	scrollback search mode is triggered by B<M-s>. You can move it to any
		484	other combination either by setting the B<searchable-scrollback> resource:
		485
		486	URxvt.searchable-scrollback: CM-s
		487
		488	=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
		489
		490	See next entry.
		491
		492	=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
		493
		494	These are caused by the C<readline> perl extension. Under normal
		495	circumstances, it will move your cursor around when you click into the
		496	line that contains it. It tries hard not to do this at the wrong moment,
		497	but when running a program that doesn't parse cursor movements or in some
		498	cases during rlogin sessions, it fails to detect this properly.
		499
		500	You can permamently switch this feature off by disabling the C<readline>
		501	extension:
		502
234	URxvt.perl-ext-common: default,tabbed	503	URxvt.perl-ext-common: default,-readline
235		504
236	It will also work fine with tabbing functionality of many window managers	505	=head3 My numerical keypad acts weird and generates differing output?
237	or similar tabbing programs, and its embedding-features allow it to be
238	embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
239	the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
240	(murxvt) terminal as an example embedding application.
241		506
242	=head2 How do I know which rxvt-unicode version I'm using?	507	Some Debian GNUL/Linux users seem to have this problem, although no
		508	specific details were reported so far. It is possible that this is caused
		509	by the wrong C<TERM> setting, although the details of wether and how
		510	this can happen are unknown, as C<TERM=rxvt> should offer a compatible
		511	keymap. See the answer to the previous question, and please report if that
		512	helped.

248		515
249	=head2 I am using Debian GNU/Linux and have a problem...	516	The most common causes for this are that either your locale is not set
		517	correctly, or you specified a B<preeditStyle> that is not supported by
		518	your input method. For example, if you specified B<OverTheSpot> and
		519	your input method (e.g. the default input method handling Compose keys)
		520	does not support this (for instance because it is not visual), then
		521	rxvt-unicode will continue without an input method.
250		522
251	The Debian GNU/Linux package of rxvt-unicode in sarge contains large	523	In this case either do not specify a B<preeditStyle> or specify more than

254	the original rxvt-unicode author please download and install the genuine

256	the problem. If you cannot, chances are that the problems are specific to
257	Debian GNU/Linux, in which case it should be reported via the Debian Bug
258	Tracking System (use C<reportbug> to report the bug).

		649	applications. Most importantly, this means that if you or your OS loads
		650	resources into the X display (the right way to do it), rxvt-unicode will
		651	ignore any resource files in your home directory. It will only read
		652	F<$HOME/.Xdefaults> when no resources are attached to the display.
		653
		654	If you have or use an F<$HOME/.Xresources> file, chances are that
		655	resources are loaded into your X-server. In this case, you have to

461	In that case, select a font of your taste and add it to the font list,	820	The reasons is that there exists a perfectly fine mechanism for selecting

469	search and use less resources within rxvt-unicode and the X-server.
470
471	The only limitation is that none of the fonts may be larger than the base
472	font, as the base font defines the terminal character cell size, which
473	must be the same due to the way terminals work.
474
475	=head2 Why do some chinese characters look so different than others?
476
477	This is because there is a difference between script and language --
478	rxvt-unicode does not know which language the text that is output is,
479	as it only knows the unicode character codes. If rxvt-unicode first
480	sees a japanese/chinese character, it might choose a japanese font for
481	display. Subsequent japanese characters will use that font. Now, many
482	chinese characters aren't represented in japanese fonts, so when the first
483	non-japanese character comes up, rxvt-unicode will look for a chinese font
484	-- unfortunately at this point, it will still use the japanese font for
485	chinese characters that are also in the japanese font.
486
487	The workaround is easy: just tag a chinese font at the end of your font
488	list (see the previous question). The key is to view the font list as
489	a preference list: If you expect more japanese, list a japanese font
490	first. If you expect more chinese, put a chinese font first.
491
492	In the future it might be possible to switch language preferences at
493	runtime (the internal data structure has no problem with using different
494	fonts for the same character at the same time, but no interface for this
495	has been designed yet).
496
497	Until then, you might get away with switching fonts at runtime (see L<Can
498	I switch the fonts at runtime?> later in this document).
499
500	=head2 Why does rxvt-unicode sometimes leave pixel droppings?
501
502	Most fonts were not designed for terminal use, which means that character
503	size varies a lot. A font that is otherwise fine for terminal use might
504	contain some characters that are simply too wide. Rxvt-unicode will avoid
505	these characters. For characters that are just "a bit" too wide a special
506	"careful" rendering mode is used that redraws adjacent characters.
507
508	All of this requires that fonts do not lie about character sizes,
509	however: Xft fonts often draw glyphs larger than their acclaimed bounding
510	box, and rxvt-unicode has no way of detecting this (the correct way is to
511	ask for the character bounding box, which unfortunately is wrong in these
512	cases).	826	locales).
513		827
514	It's not clear (to me at least), wether this is a bug in Xft, freetype,	828	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
515	or the respective font. If you encounter this problem you might try using	829	programs doing the same (that is, most) will automatically agree in the

517	might be forced to use a different font.
518		831
519	All of this is not a problem when using X11 core fonts, as their bounding	832	Unfortunately, there is no system-independent way to select locales, nor
520	box data is correct.	833	is there a standard on how locale specifiers will look like.
521		834
		835	On most systems, the content of the C<LC_CTYPE> environment variable
		836	contains an arbitrary string which corresponds to an already-installed
		837	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
		838	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
		839	(i.e. C<de> or C<german>) are also common.
		840
		841	Rxvt-unicode ignores all other locale categories, and except for
		842	the encoding, ignores country or language-specific settings,
		843	i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
		844	rxvt-unicode.
		845
		846	If you want to use a specific encoding you have to make sure you start
		847	rxvt-unicode with the correct C<LC_CTYPE> category.
		848
		849	=head3 Can I switch locales at runtime?
		850
		851	Yes, using an escape sequence. Try something like this, which sets
		852	rxvt-unicode's idea of C<LC_CTYPE>.
		853
		854	printf '\e]701;%s\007' ja_JP.SJIS
		855
		856	See also the previous answer.
		857
		858	Sometimes this capability is rather handy when you want to work in
		859	one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
		860	(e.g. UTF-8). For example, I use this script to start C<xjdic>, which
		861	first switches to a locale supported by xjdic and back later:
		862
		863	printf '\e]701;%s\007' ja_JP.SJIS
		864	xjdic -js
		865	printf '\e]701;%s\007' de_DE.UTF-8
		866
		867	You can also use xterm's C<luit> program, which usually works fine, except
		868	for some locales where character width differs between program- and
		869	rxvt-unicode-locales.
		870
		871	=head3 My input method wants <some encoding> but I want UTF-8, what can I do?
		872
		873	You can specify separate locales for the input method and the rest of the
		874	terminal, using the resource C<imlocale>:
		875
		876	URxvt.imlocale: ja_JP.EUC-JP
		877
		878	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
		879	use your input method. Please note, however, that you will not be able to
		880	input characters outside C<EUC-JP> in a normal way then, as your input
		881	method limits you.
		882
		883	=head3 Rxvt-unicode crashes when the X Input Method changes or exits.
		884
		885	Unfortunately, this is unavoidable, as the XIM protocol is racy by
		886	design. Applications can avoid some crashes at the expense of memory
		887	leaks, and Input Methods can avoid some crashes by careful ordering at
		888	exit time. B<kinput2> (and derived input methods) generally succeeds,
		889	while B<SCIM> (or similar input methods) fails. In the end, however,
		890	crashes cannot be completely avoided even if both sides cooperate.
		891
		892	So the only workaround is not to kill your Input Method Servers.

		895	=head2 Operating Systems / Package Maintaining
		896
		897	=head3 I am using Debian GNU/Linux and have a problem...
		898
		899	The Debian GNU/Linux package of rxvt-unicode in sarge contains large
		900	patches that considerably change the behaviour of rxvt-unicode (but
		901	unfortunately this notice has been removed). Before reporting a bug to
		902	the original rxvt-unicode author please download and install the genuine
		903	version (L<http://software.schmorp.de#rxvt-unicode>) and try to reproduce
		904	the problem. If you cannot, chances are that the problems are specific to
		905	Debian GNU/Linux, in which case it should be reported via the Debian Bug
		906	Tracking System (use C<reportbug> to report the bug).
		907
		908	For other problems that also affect the Debian package, you can and
		909	probably should use the Debian BTS, too, because, after all, it's also a
		910	bug in the Debian version and it serves as a reminder for other users that
		911	might encounter the same issue.
		912
		913	=head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
		914
		915	You should build one binary with the default options. F<configure>
		916	now enables most useful options, and the trend goes to making them
		917	runtime-switchable, too, so there is usually no drawback to enbaling them,
		918	except higher disk and possibly memory usage. The perl interpreter should
		919	be enabled, as important functionality (menus, selection, likely more in
		920	the future) depends on it.
		921
		922	You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
		923	system-wide (except maybe with C<defaults>). This will result in useful
		924	behaviour. If your distribution aims at low memory, add an empty
		925	C<perl-ext-common> resource to the app-defaults file. This will keep the
		926	perl interpreter disabled until the user enables it.
		927
		928	If you can/want build more binaries, I recommend building a minimal
		929	one with C<--disable-everything> (very useful) and a maximal one with
		930	C<--enable-everything> (less useful, it will be very big due to a lot of
		931	encodings built-in that increase download times and are rarely used).
		932
		933	=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
		934
		935	It should be, starting with release 7.1. You are encouraged to properly
		936	install urxvt with privileges necessary for your OS now.
		937
		938	When rxvt-unicode detects that it runs setuid or setgid, it will fork
		939	into a helper process for privileged operations (pty handling on some
		940	systems, utmp/wtmp/lastlog handling on others) and drop privileges
		941	immediately. This is much safer than most other terminals that keep
		942	privileges while running (but is more relevant to urxvt, as it contains
		943	things as perl interpreters, which might be "helpful" to attackers).
		944
		945	This forking is done as the very first within main(), which is very early
		946	and reduces possible bugs to initialisation code run before main(), or
		947	things like the dynamic loader of your system, which should result in very
		948	little risk.

530	=head2 My Compose (Multi_key) key is no longer working.
531
532	The most common causes for this are that either your locale is not set
533	correctly, or you specified a B<preeditStyle> that is not supported by
534	your input method. For example, if you specified B<OverTheSpot> and
535	your input method (e.g. the default input method handling Compose keys)
536	does not support this (for instance because it is not visual), then
537	rxvt-unicode will continue without an input method.
538
539	In this case either do not specify a B<preeditStyle> or specify more than
540	one pre-edit style, such as B<OverTheSpot,Root,None>.
541
542	=head2 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755

544	Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
545	international keyboards) or simply use ISO 14755 support to your
546	advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
547	codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
548	character and so on.
549
550	=head2 How can I keep rxvt-unicode from using reverse video so much?
551
552	First of all, make sure you are running with the right terminal settings
553	(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
554	make sure you have specified colours for italic and bold, as otherwise
555	rxvt-unicode might use reverse video to simulate the effect:
556
557	URxvt.colorBD: white
558	URxvt.colorIT: green
559
560	=head2 Some programs assume totally weird colours (red instead of blue), how can I fix that?
561
562	For some unexplainable reason, some rare programs assume a very weird
563	colour palette when confronted with a terminal with more than the standard
564	8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
565	these programs not to assume non-ISO colours without very good reasons.
566
567	In the meantime, you can either edit your C<rxvt-unicode> terminfo
568	definition to only claim 8 colour support or use C<TERM=rxvt>, which will
569	fix colours but keep you from using other rxvt-unicode features.

621	=head2 How does rxvt-unicode determine the encoding to use?
622
623	=head2 Is there an option to switch encodings?
624
625	Unlike some other terminals, rxvt-unicode has no encoding switch, and no
626	specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
627	UTF-8 or any other encodings with respect to terminal I/O.
628
629	The reasons is that there exists a perfectly fine mechanism for selecting
630	the encoding, doing I/O and (most important) communicating this to all
631	applications so everybody agrees on character properties such as width
632	and code number. This mechanism is the I<locale>. Applications not using
633	that info will have problems (for example, C<xterm> gets the width of
634	characters wrong as it uses it's own, locale-independent table under all
635	locales).
636
637	Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
638	programs doing the same (that is, most) will automatically agree in the
639	interpretation of characters.
640
641	Unfortunately, there is no system-independent way to select locales, nor
642	is there a standard on how locale specifiers will look like.
643
644	On most systems, the content of the C<LC_CTYPE> environment variable
645	contains an arbitrary string which corresponds to an already-installed
646	locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
647	C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
648	(i.e. C<de> or C<german>) are also common.
649
650	Rxvt-unicode ignores all other locale categories, and except for

670	first switches to a locale supported by xjdic and back later:
671
672	printf '\e]701;%s\007' ja_JP.SJIS
673	xjdic -js
674	printf '\e]701;%s\007' de_DE.UTF-8
675
676	You can also use xterm's C<luit> program, which usually works fine, except
677	for some locales where character width differs between program- and
678	rxvt-unicode-locales.
679
680	=head2 Can I switch the fonts at runtime?
681
682	Yes, using an escape sequence. Try something like this, which has the same
683	effect as using the C<-fn> switch, and takes effect immediately:
684
685	printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
686
687	This is useful if you e.g. work primarily with japanese (and prefer a
688	japanese font), but you have to switch to chinese temporarily, where
689	japanese fonts would only be in your way.
690
691	You can think of this as a kind of manual ISO-2022 switching.
692
693	=head2 Why do italic characters look as if clipped?
694
695	Many fonts have difficulties with italic characters and hinting. For
696	example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
697	Mono> completely fails in it's italic face. A workaround might be to
698	enable freetype autohinting, i.e. like this:
699
700	URxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
701	URxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
702
703	=head2 My input method wants <some encoding> but I want UTF-8, what can I do?
704
705	You can specify separate locales for the input method and the rest of the
706	terminal, using the resource C<imlocale>:
707
708	URxvt.imlocale: ja_JP.EUC-JP
709
710	Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still
711	use your input method. Please note, however, that you will not be able to
712	input characters outside C<EUC-JP> in a normal way then, as your input
713	method limits you.
714
715	=head2 Rxvt-unicode crashes when the X Input Method changes or exits.
716
717	Unfortunately, this is unavoidable, as the XIM protocol is racy by
718	design. Applications can avoid some crashes at the expense of memory
719	leaks, and Input Methods can avoid some crashes by careful ordering at
720	exit time. B<kinput2> (and derived input methods) generally succeeds,
721	while B<SCIM> (or similar input methods) fails. In the end, however,
722	crashes cannot be completely avoided even if both sides cooperate.
723
724	So the only workaround is not to kill your Input Method Servers.
725
726	=head2 Rxvt-unicode uses gobs of memory, how can I reduce that?
727
728	Rxvt-unicode tries to obey the rule of not charging you for something you
729	don't use. One thing you should try is to configure out all settings that
730	you don't need, for example, Xft support is a resource hog by design,
731	when used. Compiling it out ensures that no Xft font will be loaded
732	accidentally when rxvt-unicode tries to find a font for your characters.
733
734	Also, many people (me included) like large windows and even larger
735	scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
736	6 bytes per screen cell. For a 160x?? window this amounts to almost a
737	kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
738	use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
739	rxvt-unicode then uses 8 bytes per screen cell.
740
741	=head2 Can I speed up Xft rendering somehow?
742
743	Yes, the most obvious way to speed it up is to avoid Xft entirely, as
744	it is simply slow. If you still want Xft fonts you might try to disable
745	antialiasing (by appending C<:antialias=false>), which saves lots of
746	memory and also speeds up rendering considerably.
747
748	=head2 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
749
750	Rxvt-unicode will use whatever you specify as a font. If it needs to
751	fall back to it's default font search list it will prefer X11 core
752	fonts, because they are small and fast, and then use Xft fonts. It has
753	antialiasing disabled for most of them, because the author thinks they
754	look best that way.
755
756	If you want antialiasing, you have to specify the fonts manually.
757
758	=head2 Mouse cut/paste suddenly no longer works.
759
760	Make sure that mouse reporting is actually turned off since killing
761	some editors prematurely may leave the mouse in mouse report mode. I've
762	heard that tcsh may use mouse reporting unless it otherwise specified. A
763	quick check is to see if cut/paste works when the Alt or Shift keys are
764	depressed.
765
766	=head2 What's with this bold/blink stuff?
767
768	If no bold colour is set via C<colorBD:>, bold will invert text using the
769	standard foreground colour.
770
771	For the standard background colour, blinking will actually make the
772	text blink when compiled with C<--enable-blinking>. with standard
773	colours. Without C<--enable-blinking>, the blink attribute will be
774	ignored.
775
776	On ANSI colours, bold/blink attributes are used to set high-intensity
777	foreground/background colors.
778
779	color0-7 are the low-intensity colors.
780
781	color8-15 are the corresponding high-intensity colors.
782
783	=head2 I don't like the screen colors. How do I change them?
784
785	You can change the screen colors at run-time using F<~/.Xdefaults>
786	resources (or as long-options).
787
788	Here are values that are supposed to resemble a VGA screen,
789	including the murky brown that passes for low-intensity yellow:
790
791	URxvt.color0: #000000
792	URxvt.color1: #A80000
793	URxvt.color2: #00A800
794	URxvt.color3: #A8A800
795	URxvt.color4: #0000A8
796	URxvt.color5: #A800A8
797	URxvt.color6: #00A8A8
798	URxvt.color7: #A8A8A8
799
800	URxvt.color8: #000054
801	URxvt.color9: #FF0054
802	URxvt.color10: #00FF54
803	URxvt.color11: #FFFF54
804	URxvt.color12: #0000FF
805	URxvt.color13: #FF00FF
806	URxvt.color14: #00FFFF
807	URxvt.color15: #FFFFFF
808
809	And here is a more complete set of non-standard colors described (not by
810	me) as "pretty girly".
811
812	URxvt.cursorColor: #dc74d1
813	URxvt.pointerColor: #dc74d1
814	URxvt.background: #0e0e0e
815	URxvt.foreground: #4ad5e1
816	URxvt.color0: #000000
817	URxvt.color8: #8b8f93
818	URxvt.color1: #dc74d1
819	URxvt.color9: #dc74d1
820	URxvt.color2: #0eb8c7
821	URxvt.color10: #0eb8c7
822	URxvt.color3: #dfe37e
823	URxvt.color11: #dfe37e
824	URxvt.color5: #9e88f0
825	URxvt.color13: #9e88f0
826	URxvt.color6: #73f7ff
827	URxvt.color14: #73f7ff
828	URxvt.color7: #e1dddd
829	URxvt.color15: #e1dddd
830
831	=head2 How can I start @@RXVT_NAME@@d in a race-free way?
832
833	Try C<@@RXVT_NAME@@d -f -o>, which tells @@RXVT_NAME@@d to open the
834	display, create the listening socket and then fork.
835
836	=head2 What's with the strange Backspace/Delete key behaviour?
837
838	Assuming that the physical Backspace key corresponds to the
839	BackSpace keysym (not likely for Linux ... see the following
840	question) there are two standard values that can be used for
841	Backspace: C<^H> and C<^?>.
842
843	Historically, either value is correct, but rxvt-unicode adopts the debian
844	policy of using C<^?> when unsure, because it's the one only only correct
845	choice :).
846
847	Rxvt-unicode tries to inherit the current stty settings and uses the value
848	of `erase' to guess the value for backspace. If rxvt-unicode wasn't
849	started from a terminal (say, from a menu or by remote shell), then the
850	system value of `erase', which corresponds to CERASE in <termios.h>, will
851	be used (which may not be the same as your stty setting).
852
853	For starting a new rxvt-unicode:
854
855	# use Backspace = ^H
856	$ stty erase ^H
857	$ @@RXVT_NAME@@
858
859	# use Backspace = ^?
860	$ stty erase ^?
861	$ @@RXVT_NAME@@
862
863	Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
864
865	For an existing rxvt-unicode:
866
867	# use Backspace = ^H
868	$ stty erase ^H
869	$ echo -n "^[[36h"
870
871	# use Backspace = ^?
872	$ stty erase ^?
873	$ echo -n "^[[36l"
874
875	This helps satisfy some of the Backspace discrepancies that occur, but
876	if you use Backspace = C<^H>, make sure that the termcap/terminfo value
877	properly reflects that.
878
879	The Delete key is a another casualty of the ill-defined Backspace problem.
880	To avoid confusion between the Backspace and Delete keys, the Delete
881	key has been assigned an escape sequence to match the vt100 for Execute
882	(C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
883
884	Some other Backspace problems:
885
886	some editors use termcap/terminfo,
887	some editors (vim I'm told) expect Backspace = ^H,
888	GNU Emacs (and Emacs-like editors) use ^H for help.
889
890	Perhaps someday this will all be resolved in a consistent manner.
891
892	=head2 I don't like the key-bindings. How do I change them?
893
894	There are some compile-time selections available via configure. Unless
895	you have run "configure" with the C<--disable-resources> option you can
896	use the `keysym' resource to alter the keystrings associated with keysyms.
897
898	Here's an example for a URxvt session started using C<@@RXVT_NAME@@ -name URxvt>
899
900	URxvt.keysym.Home: \033[1~
901	URxvt.keysym.End: \033[4~
902	URxvt.keysym.C-apostrophe: \033<C-'>
903	URxvt.keysym.C-slash: \033<C-/>
904	URxvt.keysym.C-semicolon: \033<C-;>
905	URxvt.keysym.C-grave: \033<C-`>
906	URxvt.keysym.C-comma: \033<C-,>
907	URxvt.keysym.C-period: \033<C-.>
908	URxvt.keysym.C-0x60: \033<C-`>
909	URxvt.keysym.C-Tab: \033<C-Tab>
910	URxvt.keysym.C-Return: \033<C-Return>
911	URxvt.keysym.S-Return: \033<S-Return>
912	URxvt.keysym.S-space: \033<S-Space>
913	URxvt.keysym.M-Up: \033<M-Up>
914	URxvt.keysym.M-Down: \033<M-Down>
915	URxvt.keysym.M-Left: \033<M-Left>
916	URxvt.keysym.M-Right: \033<M-Right>
917	URxvt.keysym.M-C-0: list \033<M-C- 0123456789 >
918	URxvt.keysym.M-C-a: list \033<M-C- abcdefghijklmnopqrstuvwxyz >
919	URxvt.keysym.F12: command:\033]701;zh_CN.GBK\007
920
921	See some more examples in the documentation for the B<keysym> resource.
922
923	=head2 I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
924	How do I make use of them? For example, the Sun Keyboard type 4
925	has the following mappings that rxvt-unicode doesn't recognize.
926
927	KP_Insert == Insert
928	F22 == Print
929	F27 == Home
930	F29 == Prior
931	F33 == End
932	F35 == Next
933
934	Rather than have rxvt-unicode try to accommodate all the various possible
935	keyboard mappings, it is better to use `xmodmap' to remap the keys as
936	required for your particular machine.
937
938	=head2 How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
939	I need this to decide about setting colors etc.
940
941	rxvt and rxvt-unicode always export the variable "COLORTERM", so you can
942	check and see if that is set. Note that several programs, JED, slrn,
943	Midnight Commander automatically check this variable to decide whether or
944	not to use color.
945
946	=head2 How do I set the correct, full IP address for the DISPLAY variable?
947
948	If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
949	insecure mode then it is possible to use the following shell script
950	snippets to correctly set the display. If your version of rxvt-unicode
951	wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
952	the COLORTERM variable can be used to distinguish rxvt-unicode from a
953	regular xterm.
954
955	Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
956	snippets:
957

960	if [ ${TERM:-foo} = xterm ]; then
961	stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
962	echo -n '^[Z'
963	read term_id
964	stty icanon echo
965	if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
966	echo -n '^[[7n' # query the rxvt we are in for the DISPLAY string
967	read DISPLAY # set it in our local shell
968	fi
969	fi
970
971	=head2 How do I compile the manual pages for myself?
972
973	You need to have a recent version of perl installed as F</usr/bin/perl>,
974	one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
975	the doc subdirectory and enter C<make alldoc>.
976
977	=head2 My question isn't answered here, can I ask a human?
978
979	Before sending me mail, you could go to IRC: C<irc.freenode.net>,
980	channel C<#rxvt-unicode> has some rxvt-unicode enthusiasts that might be
981	interested in learning about new and exciting problems (but not FAQs :).
