		41	all Gentoo systems are completely broken (missing or mismatched header
		42	files, broken compiler etc. are just the tip of the iceberg); secondly,
		43	the Gentoo maintainer thinks it is a good idea to add broken patches to
		44	the code; and lastly, it should be called Gentoo GNU/Linux.
		45
		46	For these reasons, it is impossible to support rxvt-unicode on
		47	Gentoo. Problems appearing on Gentoo systems will usually simply be
		48	ignored unless they can be reproduced on non-Gentoo systems.

		94
		95	If you want to start @@URXVT_NAME@@d automatically whenever you run
		96	@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
		97
		98	#!/bin/sh

		101	@@URXVT_NAME@@d -q -o -f

		104
		105	This tries to create a new terminal, and if fails with exit status 2,
		106	meaning it couldn't connect to the daemon, it will start the daemon and
		107	re-run the command. Subsequent invocations of the script will re-use the
		108	existing daemon.

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).

		453	=head3 Why do some chinese characters look so different than others?
		454
		455	This is because there is a difference between script and language --
		456	rxvt-unicode does not know which language the text that is output is,
		457	as it only knows the unicode character codes. If rxvt-unicode first
		458	sees a japanese/chinese character, it might choose a japanese font for
		459	display. Subsequent japanese characters will use that font. Now, many
		460	chinese characters aren't represented in japanese fonts, so when the first
		461	non-japanese character comes up, rxvt-unicode will look for a chinese font
		462	-- unfortunately at this point, it will still use the japanese font for
		463	chinese characters that are also in the japanese font.
		464
		465	The workaround is easy: just tag a chinese font at the end of your font
		466	list (see the previous question). The key is to view the font list as
		467	a preference list: If you expect more japanese, list a japanese font
		468	first. If you expect more chinese, put a chinese font first.
		469
		470	In the future it might be possible to switch language preferences at
		471	runtime (the internal data structure has no problem with using different
		472	fonts for the same character at the same time, but no interface for this
		473	has been designed yet).
		474
		475	Until then, you might get away with switching fonts at runtime (see L<Can
		476	I switch the fonts at runtime?> later in this document).

		686
		687	As a rxvt or rxvt-unicode user, you are practically supposed to invest

		711
		712	This is my perl configuration. The first two set the perl library

		716
		717	The selection stuff mainly makes the selection perl-error-message aware

		786	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		787	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		788	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		789	font (different glyphs for C<;> and many other harmless characters),
		790	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		791	bold version has less chars than the medium version, so I use it for rare
		792	characters, too. When editing sources with vim, I use italic for comments
		793	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		794
		795	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		796	purposes, it works, and gives a different look, as my normal (Non-bold)
		797	font is already bold, and I want to see a difference between bold and
		798	normal fonts.
		799
		800	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		801	class name. Thats because I use different configs for different purposes,
		802	for example, my IRC window is started with C<-name IRC>, and uses these
		803	defaults:
		804
		805	IRC*title: IRC
		806	IRC*geometry: 87x12+535+542

		814
		815	C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
		816	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		817	stuff while keeping a very small window. If somebody pastes something

		1200	=head3 Character widths are not correct.
		1201
		1202	urxvt uses the system wcwidth function to know the information about
		1203	the width of characters, so on systems with incorrect locale data you
		1204	will likely get bad results. Two notorious examples are Solaris 9,
		1205	where single-width characters like U+2514 are reported as double-width,
		1206	and Darwin 8, where combining chars are reported having width 1.
		1207
		1208	The solution is to upgrade your system or switch to a better one. A
		1209	possibly working workaround is to use a wcwidth implementation like
