		45	For these reasons, it is impossible to support rxvt-unicode on

		93
		94	If you want to start @@URXVT_NAME@@d automatically whenever you run
		95	@@URXVT_NAME@@c and the daemon isn't running yet, use this script:
		96
		97	#!/bin/sh
		98	@@URXVT_NAME@@c "$@"

		100	@@URXVT_NAME@@d -q -o -f
		101	@@URXVT_NAME@@c "$@"
		102	fi
		103
		104	This tries to create a new terminal, and if fails with exit status 2,
		105	meaning it couldn't connect to the daemon, it will start the daemon and
		106	re-run the command. Subsequent invocations of the script will re-use the

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).

		457	=head3 Why do some chinese characters look so different than others?
		458
		459	This is because there is a difference between script and language --
		460	rxvt-unicode does not know which language the text that is output is,
		461	as it only knows the unicode character codes. If rxvt-unicode first
		462	sees a japanese/chinese character, it might choose a japanese font for
		463	display. Subsequent japanese characters will use that font. Now, many
		464	chinese characters aren't represented in japanese fonts, so when the first
		465	non-japanese character comes up, rxvt-unicode will look for a chinese font
		466	-- unfortunately at this point, it will still use the japanese font for
		467	chinese characters that are also in the japanese font.
		468
		469	The workaround is easy: just tag a chinese font at the end of your font
		470	list (see the previous question). The key is to view the font list as
		471	a preference list: If you expect more japanese, list a japanese font
		472	first. If you expect more chinese, put a chinese font first.
		473
		474	In the future it might be possible to switch language preferences at
		475	runtime (the internal data structure has no problem with using different
		476	fonts for the same character at the same time, but no interface for this
		477	has been designed yet).
		478
		479	Until then, you might get away with switching fonts at runtime (see L<Can
		480	I switch the fonts at runtime?> later in this document).

		488	=head3 Why is the cursor now blinking in emacs/vi/...?
		489
		490	This is likely caused by your editor/program's use of the C<cvvis>
		491	terminfo capability. Emacs uses it by default, as well as some versions of
		492	vi and possibly other programs.
		493
		494	In emacs, you can switch that off by adding this to your C<.emacs> file:

		496	(setq visible-cursor nil)
		497
		498	For other programs, if they do not have an option, your have to remove the

		500
		501	When @@URXVT_NAME@@ first added the blinking cursor option, it didn't
		502	add a C<cvvis> capability, which served no purpose before. Version 9.21
		503	introduced C<cvvis> (and the ability to control blinking independent of
		504	cursor shape) for compatibility with other terminals, which traditionally
		505	use a blinking cursor for C<cvvis>. This also reflects the intent of
		506	programs such as emacs, who expect C<cvvis> to enable a blinking cursor.

		717	relevant file and go to the error line number.
		718
		719	URxvt.scrollstyle: plain
		720	URxvt.secondaryScroll: true
		721
		722	As the documentation says: plain is the preferred scrollbar for the
		723	author. The C<secondaryScroll> configures urxvt to scroll in full-screen
		724	apps, like screen, so lines scrolled out of screen end up in urxvt's
		725	scrollback buffer.
		726

		732	URxvt.throughColor: #8080f0
		733	URxvt.highlightColor: #f0f0f0
		734
		735	Some colours. Not sure which ones are being used or even non-defaults, but
		736	these are in my .Xdefaults. Most notably, they set foreground/background
		737	to light gray/black, and also make sure that the colour 7 matches the
		738	default foreground colour.
		739
		740	URxvt.underlineColor: yellow
		741
		742	Another colour, makes underline lines look different. Sometimes hurts, but
		743	is mostly a nice effect.
		744

		746	URxvt.loginShell: false
		747	URxvt.meta: ignore

		758
		759	The only case I use it is for my IRC window, which I like to keep
		760	iconified till people msg me (which beeps).
		761
		762	URxvt.visualBell: true

		782	urxvt.boldItalicFont: xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
		783
		784	I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
		785	overwhelmed. A special note: the C<9x15bold> mentioned above is actually
		786	the version from XFree-3.3, as XFree-4 replaced it by a totally different
		787	font (different glyphs for C<;> and many other harmless characters),
		788	while the second font is actually the C<9x15bold> from XFree4/XOrg. The
		789	bold version has less chars than the medium version, so I use it for rare
		790	characters, too. When editing sources with vim, I use italic for comments
		791	and other stuff, which looks quite good with Bitstream Vera anti-aliased.
		792
		793	Terminus is a quite bad font (many very wrong glyphs), but for most of my
		794	purposes, it works, and gives a different look, as my normal (Non-bold)
		795	font is already bold, and I want to see a difference between bold and
		796	normal fonts.
		797
		798	Please note that I used the C<urxvt> instance name and not the C<URxvt>
		799	class name. That is because I use different configs for different purposes,
		800	for example, my IRC window is started with C<-name IRC>, and uses these
		801	defaults:
		802
		803	IRC*title: IRC
		804	IRC*geometry: 87x12+535+542
		805	IRC*saveLines: 0
		806	IRC*mapAlert: true

		811	IRC*keysym.M-C-2: command:\033]710;9x15bold\007\033]711;9x15bold\007
		812
		813	C<Alt-Ctrl-1> and C<Alt-Ctrl-2> switch between two different font
		814	sizes. C<suxuseuro> allows me to keep an eye (and actually read)
		815	stuff while keeping a very small window. If somebody pastes something
		816	complicated (e.g. japanese), I temporarily switch to a larger font.
		817
		818	The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
		819	C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
		820	file for different hosts, for example, on my main desktop, I use:
		821
		822	URxvt.keysym.C-M-q: command:\033[3;5;5t
		823	URxvt.keysym.C-M-y: command:\033[3;5;606t

		825	URxvt.keysym.C-M-c: command:\033[3;1605;606t
		826	URxvt.keysym.C-M-p: perl:test
		827
		828	The first for keysym definitions allow me to quickly bring some windows
		829	in the layout I like most. Ion users might start laughing but will stop
		830	immediately when I tell them that I use my own Fvwm2 module for much the
		831	same effect as Ion provides, and I only very rarely use the above key

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

		1186	=head3 Character widths are not correct.

		1188	urxvt uses the system wcwidth function to know the information about

		1192	and Darwin 8, where combining chars are reported having width 1.

		1987	This mode should be enabled I<before> actually enabling mouse reporting,
		1988	for semi-obvious reasons.
		1989
		1990	The sequences received for various modes are as follows:
		1991
		1992	ESC [ M o o o !1005, !1015 (three octets)
		1993	ESC [ M c c c 1005, !1015 (three characters)
		1994	ESC [ Pm M 1015 (three or more numeric parameters)
		1995
		1996	The first three parameters are C<code>, C<x> and C<y>. Code is the numeric
		1997	code as for the other modes (but encoded as a decimal number, including
		1998	the additional offset of 32, so you have to subtract 32 first), C<x> and
		1999	C<y> are the coordinates (1|1 is the upper left corner, just as with
		2000	cursor positioning).
		2001
		2002	Example: Shift-Button-1 press at top row, column 80.
		2003
		2004	ESC [ 37 ; 80 ; 1 M
		2005
		2006	One can use this feature by simply enabling it and then looking for
		2007	parameters to the C<ESC [ M> reply - if there are any, this mode is
		2008	active, otherwise one of the old reporting styles is used.
		2009
		2010	Other (to be implemented) reply sequences will use a similar encoding.
		2011
		2012	In the future, more parameters might get added (pixel coordinates for
		2013	example - anybody out there who needs this?).
