 =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.

+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:

+This tries to create a new terminal, and if fails with exit status 2,

+=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 Why does rxvt-unicode sometimes leave pixel droppings?
 Most fonts were not designed for terminal use, which means that character
 size varies a lot. A font that is otherwise fine for terminal use might
 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).

+It's not clear (to me at least), whether this is a bug in Xft, freetype,
 or the respective font. If you encounter this problem you might try using
 the C<-lsp> option to give the font more height. If that doesn't work, you
 might be forced to use a different font.
 All of this is not a problem when using X11 core fonts, as their bounding
 =head3 Can I switch the fonts at runtime?
 Yes, using an escape sequence. Try something like this, which has the same
 effect as using the C<-fn> switch, and takes effect immediately:
-   printf '\e]50;%s\007' "9x15bold,xft:Kochi Gothic"
+   printf '\33]50;%s\007' "9x15bold,xft:Kochi Gothic"
 This is useful if you e.g. work primarily with japanese (and prefer a
 japanese font), but you have to switch to chinese temporarily, where
 japanese fonts would only be in your way.
 =head3 Why do italic characters look as if clipped?
 Many fonts have difficulties with italic characters and hinting. For
 example, the otherwise very nicely hinted font C<xft:Bitstream Vera Sans
-Mono> completely fails in it's italic face. A workaround might be to
+Mono> completely fails in its italic face. A workaround might be to

    URxvt.boldItalicFont:    xft:Bitstream Vera Sans Mono:bold:italic:autohint=true

+They have been described (not by me) as "pretty girly".
 =head3 Why do some characters look so much different than others?
 See next entry.
 =head3 How does rxvt-unicode choose fonts?
 Most fonts do not contain the full range of Unicode, which is
 fine. Chances are that the font you (or the admin/package maintainer of
 your system/os) have specified does not cover all the characters you want
 to display.
 B<rxvt-unicode> makes a best-effort try at finding a replacement
 font. Often the result is fine, but sometimes the chosen font looks
 bad/ugly/wrong. Some fonts have totally strange characters that don't
 resemble the correct glyph at all, and rxvt-unicode lacks the artificial
 intelligence to detect that a specific glyph is wrong: it has to believe
 the font that the characters it claims to contain indeed look correct.
 In that case, select a font of your taste and add it to the font list,
 e.g.:
    @@URXVT_NAME@@ -fn basefont,font2,font3...
 When rxvt-unicode sees a character, it will first look at the base
 font. If the base font does not contain the character, it will go to the
 next font, and so on. Specifying your own fonts will also speed up this
 search and use less resources within rxvt-unicode and the X-server.
 The only limitation is that none of the fonts may be larger than the base
 font, as the base font defines the terminal character cell size, which
 must be the same due to the way terminals work.

+This is because there is a difference between script and language --

 =head2 Terminal Configuration
+=head3 Can I see a typical configuration?
+The default configuration tries to be xterm-like, which I don't like that
+much, but it's least surprise to regular users.
+As a rxvt or rxvt-unicode user, you are practically supposed to invest
+time into customising your terminal. To get you started, here is the

+not I<typical>, but what's typical...

+These are just for testing stuff.
+   URxvt.imLocale: ja_JP.UTF-8
+   URxvt.preeditType: OnTheSpot,None
+This tells rxvt-unicode to use a special locale when communicating with
+the X Input Method, and also tells it to only use the OnTheSpot pre-edit
+type, which requires the C<xim-onthespot> perl extension but rewards me
+with correct-looking fonts.
+   URxvt.perl-lib: /root/lib/urxvt
+   URxvt.perl-ext-common: default,selection-autotransform,selection-pastebin,xim-onthespot,remote-clipboard

+   URxvt.selection-autotransform.1: s/^ at (.*?) line (\\d+)$/:e \\Q$1\\E\\x0d:$2\\x0d/
+This is my perl configuration. The first two set the perl library
+directory and also tells urxvt to use a large number of extensions. I
+develop for myself mostly, so I actually use most of the extensions I
+write.
+The selection stuff mainly makes the selection perl-error-message aware
+and tells it to convert perl error messages into vi-commands to load the
+relevant file and go tot he error line number.
+   URxvt.scrollstyle:      plain
+   URxvt.secondaryScroll:  true
+As the documentation says: plain is the preferred scrollbar for the
+author. The C<secondaryScroll> configures urxvt to scroll in full-screen
+apps, like screen, so lines scrolled out of screen end up in urxvt's
+scrollback buffer.

+Some colours. Not sure which ones are being used or even non-defaults, but

+to light gray/black, and also make sure that the colour 7 matches the

+   urxvt.boldItalicFont:   xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
+I wrote rxvt-unicode to be able to specify fonts exactly. So don't be
+overwhelmed. A special note: the C<9x15bold> mentioned above is actually
+the version from XFree-3.3, as XFree-4 replaced it by a totally different
+font (different glyphs for C<;> and many other harmless characters),
+while the second font is actually the C<9x15bold> from XFree4/XOrg. The
+bold version has less chars than the medium version, so I use it for rare
+characters, too. When editing sources with vim, I use italic for comments
+and other stuff, which looks quite good with Bitstream Vera anti-aliased.
+Terminus is a quite bad font (many very wrong glyphs), but for most of my
+purposes, it works, and gives a different look, as my normal (Non-bold)
+font is already bold, and I want to see a difference between bold and
+normal fonts.
+Please note that I used the C<urxvt> instance name and not the C<URxvt>
+class name. Thats because I use different configs for different purposes,
+for example, my IRC window is started with C<-name IRC>, and uses these
+defaults:
+   IRC*title:              IRC
+   IRC*geometry:           87x12+535+542
+   IRC*saveLines:          0
+   IRC*mapAlert:           true
+   IRC*font:               suxuseuro
+   IRC*boldFont:           suxuseuro
+   IRC*colorBD:            white
+   IRC*keysym.M-C-1:       command:\033]710;suxuseuro\007\033]711;suxuseuro\007
+   IRC*keysym.M-C-2:       command:\033]710;9x15bold\007\033]711;9x15bold\007
+C<Alt-Shift-1> and C<Alt-Shift-2> switch between two different font
+sizes. C<suxuseuro> allows me to keep an eye (and actually read)
+stuff while keeping a very small window. If somebody pastes something
+complicated (e.g. japanese), I temporarily switch to a larger font.
+The above is all in my C<.Xdefaults> (I don't use C<.Xresources> nor
+C<xrdb>). I also have some resources in a separate C<.Xdefaults-hostname>
+file for different hosts, for example, on ym main desktop, I use:
+   URxvt.keysym.C-M-q: command:\033[3;5;5t
+   URxvt.keysym.C-M-y: command:\033[3;5;606t

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

 =head3 Why doesn't rxvt-unicode read my resources?

 applications. Most importantly, this means that if you or your OS loads

 The terminal description used by rxvt-unicode is not as widely available

 The correct solution for this problem is to install the terminfo, this can

 If you cannot or do not want to do this, then you can simply set
 C<TERM=rxvt> or even C<TERM=xterm>, and live with the small number of
 problems arising, which includes wrong keymapping, less and different
 colours and some refresh errors in fullscreen applications. It's a nice
 One reason you might want this is that some distributions or operating
 systems still compile some programs using the long-obsoleted termcap
 library (Fedora Core's bash is one example) and rely on a termcap entry
 for C<rxvt-unicode>.

 The best thing is to fix your startup environment, as you will likely run
 into other problems. If nothing works you can try this in your .profile.
-  printf '\e]701;%s\007' "$LC_CTYPE"
+  printf '\33]701;%s\007' "$LC_CTYPE"   # $LANG or $LC_ALL are worth a try, too
 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
-characters wrong as it uses it's own, locale-independent table under all
+characters wrong as it uses its own, locale-independent table under all
 locales).
 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.
 =head3 Can I switch locales at runtime?
 Yes, using an escape sequence. Try something like this, which sets
 rxvt-unicode's idea of C<LC_CTYPE>.
-  printf '\e]701;%s\007' ja_JP.SJIS
+  printf '\33]701;%s\007' ja_JP.SJIS
 See also the previous answer.
 Sometimes this capability is rather handy when you want to work in
 one locale (e.g. C<de_DE.UTF-8>) but some programs don't support it
 (e.g. UTF-8). For example, I use this script to start C<xjdic>, which
 first switches to a locale supported by xjdic and back later:
-   printf '\e]701;%s\007' ja_JP.SJIS
+   printf '\33]701;%s\007' ja_JP.SJIS
    xjdic -js
-   printf '\e]701;%s\007' de_DE.UTF-8
+   printf '\33]701;%s\007' de_DE.UTF-8
 You can also use xterm's C<luit> program, which usually works fine, except
 for some locales where character width differs between program- and

+=item - Make sure your locale I<and> the imLocale are supported on your OS.
+Try C<locale -a> or check the documentation for your OS.
+=item - Make sure your locale or imLocale matches a locale supported by your XIM.
+For example, B<kinput2> does not support UTF-8 locales, you should use
+C<ja_JP.EUC-JP> or equivalent.
+=item - Make sure your XIM server is actually running.
+=item - Make sure the C<XMODIFIERS> environment variable is set correctly when I<starting> rxvt-unicode.
+When you want to use e.g. B<kinput2>, it must be set to
+C<@im=kinput2>. For B<scim>, use C<@im=SCIM>. You can see what input

 =head3 My input method wants <some encoding> but I want UTF-8, what can I do?
 You can specify separate locales for the input method and the rest of the
 terminal, using the resource C<imlocale>:
    URxvt.imlocale: ja_JP.EUC-JP
 Now you can start your terminal with C<LC_CTYPE=ja_JP.UTF-8> and still

 =head3 Rxvt-unicode crashes when the X Input Method changes or exits.
 Unfortunately, this is unavoidable, as the XIM protocol is racy by
 design. Applications can avoid some crashes at the expense of memory
 =head3 I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
 You should build one binary with the default options. F<configure>
 now enables most useful options, and the trend goes to making them

+runtime-switchable, too, so there is usually no drawback to enabling them,
 except higher disk and possibly memory usage. The perl interpreter should
 be enabled, as important functionality (menus, selection, likely more in
 the future) depends on it.
 You should not overwrite the C<perl-ext-common> snd C<perl-ext> resources
 =head3 I am on FreeBSD and rxvt-unicode does not seem to work at all.
