+Before sending me mail, you could go to IRC: C<irc.freenode.net>,

+interested in learning about new and exciting problems (but not FAQs :).
+=head3 Does it support tabs, can I have a tabbed rxvt-unicode?
+Beginning with version 7.3, there is a perl extension that implements a
+simple tabbed terminal. It is installed by default, so any of these should
+give you tabs:
+   @@URXVT_NAME@@ -pe tabbed
+   URxvt.perl-ext-common: default,tabbed
+It will also work fine with tabbing functionality of many window managers
+or similar tabbing programs, and its embedding-features allow it to be
+embedded into other programs, as witnessed by F<doc/rxvt-tabbed> or
+the upcoming C<Gtk2::URxvt> perl module, which features a tabbed urxvt
+(murxvt) terminal as an example embedding application.

+kilobyte per line. A scrollback buffer of 10000 lines will then (if full)
+use 10 Megabytes of memory. With C<--enable-unicode3> it gets worse, as
+rxvt-unicode then uses 8 bytes per screen cell.
+=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
+   @@URXVT_NAME@@c "$@"
+   if [ $? -eq 2 ]; then
+      @@URXVT_NAME@@d -q -o -f
+      @@URXVT_NAME@@c "$@"
+   fi
+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 wether 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 How do I set the correct, full IP address for the DISPLAY variable?
+If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
+insecure mode then it is possible to use the following shell script
+snippets to correctly set the display. If your version of rxvt-unicode
+wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
+the COLORTERM variable can be used to distinguish rxvt-unicode from a
+regular xterm.
+Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
+snippets:
+   # Bourne/Korn/POSIX family of shells:
+   [ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
+   if [ ${TERM:-foo} = xterm ]; then
+      stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
+      echo -n '^[Z'
+      read term_id
+      stty icanon echo
+      if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
+         echo -n '^[[7n'        # query the rxvt we are in for the DISPLAY string
+         read DISPLAY           # set it in our local shell
+      fi
+   fi
+=head3 How do I compile the manual pages on my own?
+You need to have a recent version of perl installed as F</usr/bin/perl>,
+one that comes with F<pod2man>, F<pod2text> and F<pod2html>. Then go to
+the doc subdirectory and enter C<make alldoc>.
+=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
+that the urxvt binary is larger (due to some encoding tables always being
+compiled in), but it actually uses less memory (RSS) after startup. Even
+with C<--disable-everything>, this comparison is a bit unfair, as many
+features unique to urxvt (locale, encoding conversion, iso14755 etc.) are
+already in use in this mode.

+  188985    9048   66616   18222    1788 urxvt --disable-everything
+When you C<--enable-everything> (which I<is> unfair, as this involves xft
+and full locale/XIM support which are quite bloaty inside libX11 and my
+libc), the two diverge, but not unreasnobaly so.

+ 1035683   49680   66648   29096    3680 urxvt --enable-everything
+The very large size of the text section is explained by the east-asian
+encoding tables, which, if unused, take up disk space but nothing else
+and can be compiled out unless you rely on X11 core fonts that use those
+encodings. The BSS size comes from the 64k emergency buffer that my c++
+compiler allocates (but of course doesn't use unless you are out of
+memory). Also, using an xft font instead of a core font immediately adds a
+few megabytes of RSS. Xft indeed is responsible for a lot of RSS even when
+not used.
+Of course, due to every character using two or four bytes instead of one,
+a large scrollback buffer will ultimately make rxvt-unicode use more
+memory.
+Compared to e.g. Eterm (5112k), aterm (3132k) and xterm (4680k), this
+still fares rather well. And compared to some monsters like gnome-terminal
+(21152k + extra 4204k in separate processes) or konsole (22200k + extra
+43180k in daemons that stay around after exit, plus half a minute of
+startup time, including the hundreds of warnings it spits out), it fares
+extremely well *g*.
+=head3 Why C++, isn't that unportable/bloated/uncool?
+Is this a question? :) It comes up very often. The simple answer is: I had
+to write it, and C++ allowed me to write and maintain it in a fraction
+of the time and effort (which is a scarce resource for me). Put even
+shorter: It simply wouldn't exist without C++.
+My personal stance on this is that C++ is less portable than C, but in
+the case of rxvt-unicode this hardly matters, as its portability limits
+are defined by things like X11, pseudo terminals, locale support and unix
+domain sockets, which are all less portable than C++ itself.
+Regarding the bloat, see the above question: It's easy to write programs
+in C that use gobs of memory, an certainly possible to write programs in
+C++ that don't. C++ also often comes with large libraries, but this is
+not necessarily the case with GCC. Here is what rxvt links against on my
+system with a minimal config:
+   libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
+   libc.so.6 => /lib/libc.so.6 (0x00002aaaaadde000)
+   libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab01d000)
+   /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
+And here is rxvt-unicode:
+   libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x00002aaaaabc3000)
+   libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaada2000)
+   libc.so.6 => /lib/libc.so.6 (0x00002aaaaaeb0000)
+   libdl.so.2 => /lib/libdl.so.2 (0x00002aaaab0ee000)
+   /lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
+No large bloated libraries (of course, none were linked in statically),
+except maybe libX11 :)
+=head2 Rendering, Font & Look and Feel Issues
+=head3 I can't get transparency working, what am I doing wrong?
+First of all, transparency isn't officially supported in rxvt-unicode, so
+you are mostly on your own. Do not bug the author about it (but you may
+bug everybody else). Also, if you can't get it working consider it a rite
+of passage: ... and you failed.
+Here are four ways to get transparency. B<Do> read the manpage and option
+descriptions for the programs mentioned and rxvt-unicode. Really, do it!
+1. Use inheritPixmap:
+   Esetroot wallpaper.jpg
+   @@URXVT_NAME@@ -ip -tint red -sh 40
+That works. If you think it doesn't, you lack transparency and tinting
+support, or you are unable to read.
+2. Use a simple pixmap and emulate pseudo-transparency. This enables you
+to use effects other than tinting and shading: Just shade/tint/whatever
+your picture with gimp or any other tool:
+   convert wallpaper.jpg -blur 20x20 -modulate 30 background.xpm
+   @@URXVT_NAME@@ -pixmap background.xpm -pe automove-background
+That works. If you think it doesn't, you lack XPM and Perl support, or you
+are unable to read.
+3. Use an ARGB visual:
+   @@URXVT_NAME@@ -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc
+This requires XFT support, and the support of your X-server. If that
+doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't
+there yet, no matter what they claim. Rxvt-Unicode contains the neccessary
+bugfixes and workarounds for Xft and Xlib to make it work, but that
+doesn't mean that your WM has the required kludges in place.
+4. Use xcompmgr and let it do the job:
+  xprop -frame -f _NET_WM_WINDOW_OPACITY 32c \
+        -set _NET_WM_WINDOW_OPACITY 0xc0000000
+Then click on a window you want to make transparent. Replace C<0xc0000000>
+by other values to change the degree of opacity. If it doesn't work and
+your server crashes, you got to keep the pieces.
+=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
+contain some characters that are simply too wide. Rxvt-unicode will avoid
+these characters. For characters that are just "a bit" too wide a special
+"careful" rendering mode is used that redraws adjacent characters.
+All of this requires that fonts do not lie about character sizes,
+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), wether 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
+box data is correct.
+=head3 How can I keep rxvt-unicode from using reverse video so much?
+First of all, make sure you are running with the right terminal settings
+(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
+make sure you have specified colours for italic and bold, as otherwise
+rxvt-unicode might use reverse video to simulate the effect:
+   URxvt.colorBD:  white
+   URxvt.colorIT:  green
+=head3 Some programs assume totally weird colours (red instead of blue), how can I fix that?
+For some unexplainable reason, some rare programs assume a very weird
+colour palette when confronted with a terminal with more than the standard
+8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
+these programs not to assume non-ISO colours without very good reasons.
+In the meantime, you can either edit your C<rxvt-unicode> terminfo
+definition to only claim 8 colour support or use C<TERM=rxvt>, which will
+fix colours but keep you from using other rxvt-unicode features.
+=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"
+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.
+You can think of this as a kind of manual ISO-2022 switching.
+=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
+enable freetype autohinting, i.e. like this:
+   URxvt.italicFont:        xft:Bitstream Vera Sans Mono:italic:autohint=true
+   URxvt.boldItalicFont:    xft:Bitstream Vera Sans Mono:bold:italic:autohint=true
+=head3 Can I speed up Xft rendering somehow?
+Yes, the most obvious way to speed it up is to avoid Xft entirely, as
+it is simply slow. If you still want Xft fonts you might try to disable
+antialiasing (by appending C<:antialias=false>), which saves lots of
+memory and also speeds up rendering considerably.
+=head3 Rxvt-unicode doesn't seem to anti-alias its fonts, what is wrong?
+Rxvt-unicode will use whatever you specify as a font. If it needs to
+fall back to it's default font search list it will prefer X11 core
+fonts, because they are small and fast, and then use Xft fonts. It has
+antialiasing disabled for most of them, because the author thinks they
+look best that way.
+If you want antialiasing, you have to specify the fonts manually.
+=head3 What's with this bold/blink stuff?
+If no bold colour is set via C<colorBD:>, bold will invert text using the
+standard foreground colour.
+For the standard background colour, blinking will actually make the
+text blink when compiled with C<--enable-blinking>. with standard
+colours. Without C<--enable-blinking>, the blink attribute will be
+ignored.
+On ANSI colours, bold/blink attributes are used to set high-intensity
+foreground/background colors.
+color0-7 are the low-intensity colors.
+color8-15 are the corresponding high-intensity colors.
+=head3 I don't like the screen colors.  How do I change them?
+You can change the screen colors at run-time using F<~/.Xdefaults>
+resources (or as long-options).
+Here are values that are supposed to resemble a VGA screen,
+including the murky brown that passes for low-intensity yellow:
+   URxvt.color0:   #000000
+   URxvt.color1:   #A80000
+   URxvt.color2:   #00A800
+   URxvt.color3:   #A8A800
+   URxvt.color4:   #0000A8
+   URxvt.color5:   #A800A8
+   URxvt.color6:   #00A8A8
+   URxvt.color7:   #A8A8A8
+   URxvt.color8:   #000054
+   URxvt.color9:   #FF0054
+   URxvt.color10:  #00FF54
+   URxvt.color11:  #FFFF54
+   URxvt.color12:  #0000FF
+   URxvt.color13:  #FF00FF
+   URxvt.color14:  #00FFFF
+   URxvt.color15:  #FFFFFF
+And here is a more complete set of non-standard colors.
+   URxvt.cursorColor:  #dc74d1
+   URxvt.pointerColor: #dc74d1
+   URxvt.background:   #0e0e0e
+   URxvt.foreground:   #4ad5e1
+   URxvt.color0:       #000000
+   URxvt.color8:       #8b8f93
+   URxvt.color1:       #dc74d1
+   URxvt.color9:       #dc74d1
+   URxvt.color2:       #0eb8c7
+   URxvt.color10:      #0eb8c7
+   URxvt.color3:       #dfe37e
+   URxvt.color11:      #dfe37e
+   URxvt.color5:       #9e88f0
+   URxvt.color13:      #9e88f0
+   URxvt.color6:       #73f7ff
+   URxvt.color14:      #73f7ff
+   URxvt.color7:       #e1dddd
+   URxvt.color15:      #e1dddd
+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.
+=head3 Why do some chinese characters look so different than others?
+This is because there is a difference between script and language --
+rxvt-unicode does not know which language the text that is output is,
+as it only knows the unicode character codes. If rxvt-unicode first
+sees a japanese/chinese character, it might choose a japanese font for
+display. Subsequent japanese characters will use that font. Now, many
+chinese characters aren't represented in japanese fonts, so when the first
+non-japanese character comes up, rxvt-unicode will look for a chinese font
+-- unfortunately at this point, it will still use the japanese font for
+chinese characters that are also in the japanese font.
+The workaround is easy: just tag a chinese font at the end of your font
+list (see the previous question). The key is to view the font list as
+a preference list: If you expect more japanese, list a japanese font
+first. If you expect more chinese, put a chinese font first.
+In the future it might be possible to switch language preferences at
+runtime (the internal data structure has no problem with using different
+fonts for the same character at the same time, but no interface for this
+has been designed yet).
+Until then, you might get away with switching fonts at runtime (see L<Can
+I switch the fonts at runtime?> later in this document).
+=head2 Keyboard, Mouse & User Interaction
+=head3 The new selection selects pieces that are too big, how can I select single words?
+If you want to select e.g. alphanumeric words, you can use the following
+setting:
+   URxvt.selection.pattern-0: ([[:word:]]+)
+If you click more than twice, the selection will be extended
+more and more.
+To get a selection that is very similar to the old code, try this pattern:
+   URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
+Please also note that the I<LeftClick Shift-LeftClik> combination also
+selects words like the old code.
+=head3 I don't like the new selection/popups/hotkeys/perl, how do I change/disable it?
+You can disable the perl extension completely by setting the
+B<perl-ext-common> resource to the empty string, which also keeps
+rxvt-unicode from initialising perl, saving memory.
+If you only want to disable specific features, you first have to
+identify which perl extension is responsible. For this, read the section
+B<PREPACKAGED EXTENSIONS> in the @@URXVT_NAME@@perl(3) manpage. For
+example, to disable the B<selection-popup> and B<option-popup>, specify
+this B<perl-ext-common> resource:
+   URxvt.perl-ext-common: default,-selection-popup,-option-popup
+This will keep the default extensions, but disable the two popup
+extensions. Some extensions can also be configured, for example,
+scrollback search mode is triggered by B<M-s>. You can move it to any
+other combination either by setting the B<searchable-scrollback> resource:
+   URxvt.searchable-scrollback: CM-s
+=head3 The cursor moves when selecting text in the current input line, how do I switch this off?
+See next entry.
+=head3 During rlogin/ssh/telnet/etc. sessions, clicking near the cursor outputs strange escape sequences, how do I fix this?
+These are caused by the C<readline> perl extension. Under normal
+circumstances, it will move your cursor around when you click into the
+line that contains it. It tries hard not to do this at the wrong moment,
+but when running a program that doesn't parse cursor movements or in some
+cases during rlogin sessions, it fails to detect this properly.
+You can permamently switch this feature off by disabling the C<readline>
+extension:
+   URxvt.perl-ext-common: default,-readline
+=head3 My numerical keypad acts weird and generates differing output?
+Some Debian GNUL/Linux users seem to have this problem, although no
+specific details were reported so far. It is possible that this is caused
+by the wrong C<TERM> setting, although the details of wether and how
+this can happen are unknown, as C<TERM=rxvt> should offer a compatible
+keymap. See the answer to the previous question, and please report if that
+helped.
+=head3 My Compose (Multi_key) key is no longer working.
+The most common causes for this are that either your locale is not set
+correctly, or you specified a B<preeditStyle> that is not supported by
+your input method. For example, if you specified B<OverTheSpot> and
+your input method (e.g. the default input method handling Compose keys)
+does not support this (for instance because it is not visual), then
+rxvt-unicode will continue without an input method.
+In this case either do not specify a B<preeditStyle> or specify more than
+one pre-edit style, such as B<OverTheSpot,Root,None>.
+=head3 I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
+Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
+international keyboards) or simply use ISO 14755 support to your
+advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
+codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
+character and so on.
+=head3 Mouse cut/paste suddenly no longer works.
+Make sure that mouse reporting is actually turned off since killing
+some editors prematurely may leave the mouse in mouse report mode. I've
+heard that tcsh may use mouse reporting unless it otherwise specified. A
+quick check is to see if cut/paste works when the Alt or Shift keys are
+depressed.
+=head3 What's with the strange Backspace/Delete key behaviour?
+Assuming that the physical Backspace key corresponds to the
+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 only 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
+system value of `erase', which corresponds to CERASE in <termios.h>, will
+be used (which may not be the same as your stty setting).
+For starting a new rxvt-unicode:
+   # use Backspace = ^H
+   $ stty erase ^H
+   $ @@URXVT_NAME@@
+   # use Backspace = ^?
+   $ stty erase ^?
+   $ @@URXVT_NAME@@
+Toggle with C<ESC [ 36 h> / C<ESC [ 36 l>.
+For an existing rxvt-unicode:
+   # use Backspace = ^H
+   $ stty erase ^H
+   $ echo -n "^[[36h"
+   # use Backspace = ^?
+   $ stty erase ^?
+   $ echo -n "^[[36l"
+This helps satisfy some of the Backspace discrepancies that occur, but
+if you use Backspace = C<^H>, make sure that the termcap/terminfo value
+properly reflects that.
+The Delete key is a another casualty of the ill-defined Backspace problem.
+To avoid confusion between the Backspace and Delete keys, the Delete
+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:

+=head2 Terminal Configuration
+=head3 Why doesn't rxvt-unicode read my resources?
+Well, why, indeed? It does, in a way very similar to other X
+applications. Most importantly, this means that if you or your OS loads
+resources into the X display (the right way to do it), rxvt-unicode will
+ignore any resource files in your home directory. It will only read
+F<$HOME/.Xdefaults> when no resources are attached to the display.
+If you have or use an F<$HOME/.Xresources> file, chances are that
+resources are loaded into your X-server. In this case, you have to
+re-login after every change (or run F<xrdb -merge $HOME/.Xresources>).
+Also consider the form resources have to use:
+  URxvt.resource: value
+If you want to use another form (there are lots of different ways of

 Make sure you are using C<TERM=rxvt-unicode>. Some pre-packaged
 distributions (most notably Debian GNU/Linux) break rxvt-unicode
 by setting C<TERM> to C<rxvt>, which doesn't have these extra
 features. Unfortunately, some of these (most notably, again, Debian
 GNU/Linux) furthermore fail to even install the C<rxvt-unicode> terminfo
 file, so you will need to install it on your own (See the question B<When

+=head3 Unicode does not seem to work?
 If you encounter strange problems like typing an accented character but
 getting two unrelated other characters or similar, or if program output is
 subtly garbled, then you should check your locale settings.
 If nothing works and you are sure that everything is set correctly then
 you will need to remember a little known fact: Some programs just don't
 support locales :(
-=item Why do some characters look so much different than others?
-=item 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.:
-   @@RXVT_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.
-=item Why do some chinese characters look so different than others?
-This is because there is a difference between script and language --
-rxvt-unicode does not know which language the text that is output is,
-as it only knows the unicode character codes. If rxvt-unicode first
-sees a japanese/chinese character, it might choose a japanese font for
-display. Subsequent japanese characters will use that font. Now, many
-chinese characters aren't represented in japanese fonts, so when the first
-non-japanese character comes up, rxvt-unicode will look for a chinese font
--- unfortunately at this point, it will still use the japanese font for
-chinese characters that are also in the japanese font.
-The workaround is easy: just tag a chinese font at the end of your font
-list (see the previous question). The key is to view the font list as
-a preference list: If you expect more japanese, list a japanese font
-first. If you expect more chinese, put a chinese font first.
-In the future it might be possible to switch language preferences at
-runtime (the internal data structure has no problem with using different
-fonts for the same character at the same time, but no interface for this
-has been designed yet).
-Until then, you might get away with switching fonts at runtime (see L<Can
-I switch the fonts at runtime?> later in this document).
-=item 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
-contain some characters that are simply too wide. Rxvt-unicode will avoid
-these characters. For characters that are just "a bit" too wide a special
-"careful" rendering mode is used that redraws adjacent characters.
-All of this requires that fonts do not lie about character sizes,
-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), wether 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
-box data is correct.
-=item My Compose (Multi_key) key is no longer working.
-The most common causes for this are that either your locale is not set
-correctly, or you specified a B<preeditStyle> that is not supported by
-your input method. For example, if you specified B<OverTheSpot> and
-your input method (e.g. the default input method handling Compose keys)
-does not support this (for instance because it is not visual), then
-rxvt-unicode will continue without an input method.
-In this case either do not specify a B<preeditStyle> or specify more than
-one pre-edit style, such as B<OverTheSpot,Root,None>.
-=item I cannot type C<Ctrl-Shift-2> to get an ASCII NUL character due to ISO 14755
-Either try C<Ctrl-2> alone (it often is mapped to ASCII NUL even on
-international keyboards) or simply use ISO 14755 support to your
-advantage, typing <Ctrl-Shift-0> to get a ASCII NUL. This works for other
-codes, too, such as C<Ctrl-Shift-1-d> to type the default telnet escape
-character and so on.
-=item How can I keep rxvt-unicode from using reverse video so much?
-First of all, make sure you are running with the right terminal settings
-(C<TERM=rxvt-unicode>), which will get rid of most of these effects. Then
-make sure you have specified colours for italic and bold, as otherwise
-rxvt-unicode might use reverse video to simulate the effect:
-   URxvt.colorBD:  white
-   URxvt.colorIT:  green
-=item Some programs assume totally weird colours (red instead of blue), how can I fix that?
-For some unexplainable reason, some rare programs assume a very weird
-colour palette when confronted with a terminal with more than the standard
-8 colours (rxvt-unicode supports 88). The right fix is, of course, to fix
-these programs not to assume non-ISO colours without very good reasons.
-In the meantime, you can either edit your C<rxvt-unicode> terminfo
-definition to only claim 8 colour support or use C<TERM=rxvt>, which will
-fix colours but keep you from using other rxvt-unicode features.
-=item I am on FreeBSD and rxvt-unicode does not seem to work at all.
-Rxvt-unicode requires the symbol C<__STDC_ISO_10646__> to be defined
-in your compile environment, or an implementation that implements it,
-wether it defines the symbol or not. C<__STDC_ISO_10646__> requires that
-B<wchar_t> is represented as unicode.
-As you might have guessed, FreeBSD does neither define this symobl nor
-does it support it. Instead, it uses it's own internal representation of
-B<wchar_t>. This is, of course, completely fine with respect to standards.
-However, C<__STDC_ISO_10646__> is the only sane way to support
-multi-language apps in an OS, as using a locale-dependent (and
-non-standardized) representation of B<wchar_t> makes it impossible to
-convert between B<wchar_t> (as used by X11 and your applications) and any
-other encoding without implementing OS-specific-wrappers for each and
-every locale. There simply are no APIs to convert B<wchar_t> into anything
-except the current locale encoding.
-Some applications (such as the formidable B<mlterm>) work around this
-by carrying their own replacement functions for character set handling
-with them, and either implementing OS-dependent hacks or doing multiple
-conversions (which is slow and unreliable in case the OS implements
-encodings slightly different than the terminal emulator).
-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 :)

 Unfortunately, this is unavoidable, as the XIM protocol is racy by

 leaks, and Input Methods can avoid some crashes by careful ordering at

+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
+single font). I recommend starting the X-server in C<-multiwindow> or
+C<-rootless> mode instead, which will result in similar look&feel as the
+old libW11 emulation.
-=item What's with the strange Backspace/Delete key behaviour?
+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.
-Assuming that the physical Backspace key corresponds to the
-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 only 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
-system value of `erase', which corresponds to CERASE in <termios.h>, will
-be used (which may not be the same as your stty setting).
-For starting a new rxvt-unicode:
-   # use Backspace = ^H
-   $ stty erase ^H
-   $ @@RXVT_NAME@@
-   # use Backspace = ^?
-   $ stty erase ^?
-   $ @@RXVT_NAME@@
-Toggle with C<ESC [ 36 h> / C<ESC [ 36 l> as documented in @@RXVT_NAME@@(7).
-For an existing rxvt-unicode:
-   # use Backspace = ^H
-   $ stty erase ^H
-   $ echo -n "^[[36h"
-   # use Backspace = ^?
-   $ stty erase ^?
-   $ echo -n "^[[36l"
-This helps satisfy some of the Backspace discrepancies that occur, but
-if you use Backspace = C<^H>, make sure that the termcap/terminfo value
-properly reflects that.
-The Delete key is a another casualty of the ill-defined Backspace problem.
-To avoid confusion between the Backspace and Delete keys, the Delete
-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.
-=item I don't like the key-bindings.  How do I change them?
-There are some compile-time selections available via configure. Unless
-you have run "configure" with the C<--disable-resources> option you can
-use the `keysym' resource to alter the keystrings associated with keysyms.
-Here's an example for a URxvt session started using C<@@RXVT_NAME@@ -name URxvt>

-=item I'm using keyboard model XXX that has extra Prior/Next/Insert keys.
-How do I make use of them?  For example, the Sun Keyboard type 4
-has the following mappings that rxvt-unicode doesn't recognize.
-   KP_Insert == Insert
-   F22 == Print
-   F27 == Home
-   F29 == Prior
-   F33 == End
-   F35 == Next
-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.
-=item How do I distinguish wether I'm running rxvt-unicode or a regular xterm?
-I need this to decide about setting colors etc.
-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.
-=item How do I set the correct, full IP address for the DISPLAY variable?
-If you've compiled rxvt-unicode with DISPLAY_IS_IP and have enabled
-insecure mode then it is possible to use the following shell script
-snippets to correctly set the display. If your version of rxvt-unicode
-wasn't also compiled with ESCZ_ANSWER (as assumed in these snippets) then
-the COLORTERM variable can be used to distinguish rxvt-unicode from a
-regular xterm.
-Courtesy of Chuck Blake <cblake@BBN.COM> with the following shell script
-snippets:
-   # Bourne/Korn/POSIX family of shells:
-   [ ${TERM:-foo} = foo ] && TERM=xterm # assume an xterm if we don't know
-   if [ ${TERM:-foo} = xterm ]; then
-      stty -icanon -echo min 0 time 15 # see if enhanced rxvt or not
-      echo -n '^[Z'
-      read term_id
-      stty icanon echo
-      if [ ""${term_id} = '^[[?1;2C' -a ${DISPLAY:-foo} = foo ]; then
-         echo -n '^[[7n'     	# query the rxvt we are in for the DISPLAY string
-         read DISPLAY     	# set it in our local shell
-      fi
-   fi
-=item How do I compile the manual pages for myself?

-B<< The exact syntax used is I<almost> solidified. >>
-In the menus, B<DON'T> try to use menuBar commands that add or remove a
-menuBar.
-Note that in all of the commands, the B<< I</path/> >> I<cannot> be
-omitted: use B<./> to specify a menu relative to the current menu.
-=head2 Overview of menuBar operation
-For the menuBar XTerm escape sequence C<ESC ] 703 ; Pt ST>, the syntax
-of C<Pt> can be used for a variety of tasks:
-At the top level is the current menuBar which is a member of a circular
-linked-list of other such menuBars.
-The menuBar acts as a parent for the various drop-down menus, which in
-turn, may have labels, separator lines, menuItems and subMenus.
-The menuItems are the useful bits: you can use them to mimic keyboard
-input or even to send text or escape sequences back to rxvt.
-The menuBar syntax is intended to provide a simple yet robust method of
-constructing and manipulating menus and navigating through the
-menuBars.
-The first step is to use the tag B<< [menu:I<name>] >> which creates
-the menuBar called I<name> and allows access. You may now or menus,
-subMenus, and menuItems. Finally, use the tag B<[done]> to set the
-menuBar access as B<readonly> to prevent accidental corruption of the
-menus. To re-access the current menuBar for alterations, use the tag
-B<[menu]>, make the alterations and then use B<[done]>
-X<menuBarCommands>
