 =head1 RXVT-UNICODE/URXVT FREQUENTLY ASKED QUESTIONS
 =head2 Meta, Features & Commandline Issues
 =head3 How can I start @@URXVT_NAME@@d in a race-free way?
 Try C<@@URXVT_NAME@@d -f -o>, which tells @@URXVT_NAME@@d to open the
 display, create the listening socket and then fork.

+=head3 How can I start @@URXVT_NAME@@d automatically when I run @@URXVT_NAME@@c?
 If you want to start @@URXVT_NAME@@d automatically whenever you run
 @@URXVT_NAME@@c and the daemon isn't running yet, use this script:
    #!/bin/sh
 This tries to create a new terminal, and if fails with exit status 2,
 meaning it couldn't connect to the daemon, it will start the daemon and
 re-run the command. Subsequent invocations of the script will re-use the
 existing daemon.

+=head3 How do I distinguish whether I'm running rxvt-unicode or a regular xterm? I need this to decide about setting colors etc.
 The original rxvt and rxvt-unicode always export the variable "COLORTERM",
 so you can check and see if that is set. Note that several programs, JED,
 slrn, Midnight Commander automatically check this variable to decide
 whether or not to use color.

 =head3 Isn't rxvt-unicode supposed to be small? Don't all those features bloat?
 I often get asked about this, and I think, no, they didn't cause extra
 bloat. If you compare a minimal rxvt and a minimal urxvt, you can see

 No large bloated libraries (of course, none were linked in statically),

 =head2 Rendering, Font & Look and Feel Issues

 however: Xft fonts often draw glyphs larger than their acclaimed bounding
 box, and rxvt-unicode has no way of detecting this (the correct way is to
 ask for the character bounding box, which unfortunately is wrong in these
 cases).

 If you want to select e.g. alphanumeric words, you can use the following
 circumstances, it will move your cursor around when you click into the

 but when running a program that doesn't parse cursor movements or in some
 cases during rlogin sessions, it fails to detect this properly.

+Backspace keysym (not likely for Linux ... see the following
 question) there are two standard values that can be used for
 Backspace: C<^H> and C<^?>.
 Historically, either value is correct, but rxvt-unicode adopts the debian

+policy of using C<^?> when unsure, because it's the one and only correct
 choice :).
 Rxvt-unicode tries to inherit the current stty settings and uses the value
 of `erase' to guess the value for backspace.  If rxvt-unicode wasn't
 started from a terminal (say, from a menu or by remote shell), then the
 key has been assigned an escape sequence to match the vt100 for Execute
 (C<ESC [ 3 ~>) and is in the supplied termcap/terminfo.
 Some other Backspace problems:
 some editors use termcap/terminfo,
 some editors (vim I'm told) expect Backspace = ^H,
 GNU Emacs (and Emacs-like editors) use ^H for help.
 Perhaps someday this will all be resolved in a consistent manner.
 Rather than have rxvt-unicode try to accommodate all the various possible
 keyboard mappings, it is better to use `xmodmap' to remap the keys as
 required for your particular machine.
 =head2 Terminal Configuration
 =head3 Can I see a typical configuration?
 The default configuration tries to be xterm-like, which I don't like that

 =head3 When I log-in to another system it tells me about missing terminfo data?

 as that for xterm, or even rxvt (for which the same problem often arises).
 The correct solution for this problem is to install the terminfo, this can

 One reason you might want this is that some distributions or operating
 systems still compile some programs using the long-obsoleted termcap

 If this doesn't work, then maybe you use a C<LC_CTYPE> specification not
 supported on your systems. Some systems have a C<locale> command which
 displays this (also, C<perl -e0> can be used to check locale settings, as
 it will complain loudly if it cannot set the locale). If it displays something
 The reasons is that there exists a perfectly fine mechanism for selecting
 the encoding, doing I/O and (most important) communicating this to all
 applications so everybody agrees on character properties such as width
 and code number. This mechanism is the I<locale>. Applications not using
 that info will have problems (for example, C<xterm> gets the width of

 Rxvt-unicode uses the C<LC_CTYPE> locale category to select encoding. All
 programs doing the same (that is, most) will automatically agree in the
 interpretation of characters.

 This forking is done as the very first within main(), which is very early
 and reduces possible bugs to initialisation code run before main(), or
 things like the dynamic loader of your system, which should result in very
 little risk.

 However, that means rxvt-unicode only works in C<POSIX>, C<ISO-8859-1> and
 C<UTF-8> locales under FreeBSD (which all use Unicode as B<wchar_t>.
 The rxvt-unicode author insists that the right way to fix this is in the
 system libraries once and for all, instead of forcing every app to carry
 complete replacements for them :)

 =head3 How can I use rxvt-unicode under cygwin?
 rxvt-unicode should compile and run out of the box on cygwin, using
 the X11 libraries that come with cygwin. libW11 emulation is no
 longer supported (and makes no sense, either, as it only supported a
 old libW11 emulation.
 At the time of this writing, cygwin didn't seem to support any multi-byte
 encodings (you might try C<LC_CTYPE=C-UTF-8>), so you are likely limited
 to 8-bit encodings.
+=head3 Character widths are not correct.
+urxvt uses the system wcwidth function to know the information about
+the width of characters, so on systems with incorrect locale data you
+will likely get bad results. Two notorious examples are Solaris 9,
+where single-width characters like U+2514 are reported as double-width,
+and Darwin 8, where combining chars are reported having width 1.

-Add support for XPM background pixmaps.
+Add support for libAfterImage to be used for transparency and background

+SVG, TIFF, GIF, XPM, BMP, ICO, XCF, TGA and AfterStep image XML
+(L<http://www.afterstep.org/visualdoc.php?show=asimagexml>).
+This option also adds such eye candy as blending an image over the root
+background, as well as dynamic scaling and bluring of background images.
+Note that with this option enabled, @@RXVT_NAME@@'s memory footprint might
+increase by a few megabytes even if no extra features are used (mostly due
+to third-party libraries used by libAI). Memory footprint may somewhat be
+lowered if libAfterImage is configured without support for SVG.
