-more and more.
-To get a selection that is very similar to the old code, try this pattern:
+There are three big problems with Gentoo Linux: first of all, most if not
+all Gentoo systems are completely broken (missing or mismatched header
+files, broken compiler etc. are just the tip of the iceberg); secondly,
+the Gentoo maintainer thinks it is a good idea to add broken patches to
+the code; and lastly, it should be called Gentoo GNU/Linux.
-   URxvt.selection.pattern-0: ([^"&'()*,;<=>?@[\\\\]^`{|})]+)
+For these reasons, it is impossible to support rxvt-unicode on
+Gentoo. Problems appearing on Gentoo systems will usually simply be
+ignored unless they can be reproduced on non-Gentoo systems.

-You can disable the perl extension completely by setting the
+   @@URXVT_NAME@@ -pe tabbed
-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
+   URxvt.perl-ext-common: default,tabbed
-identify which perl extension is responsible. For this, read the section
-B<PREPACKAGED EXTENSIONS> in the @@RXVT_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
+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

-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
+The version number is displayed with the usage (-h). Also the escape
+sequence C<ESC [ 8 n> sets the window title to the version number. When
+using the @@URXVT_NAME@@c client, the version displayed is that of the
+daemon.
+=head3 Rxvt-unicode uses gobs of memory, how can I reduce that?
+Rxvt-unicode tries to obey the rule of not charging you for something you
+don't use. One thing you should try is to configure out all settings that
+you don't need, for example, Xft support is a resource hog by design,
+when used. Compiling it out ensures that no Xft font will be loaded
+accidentally when rxvt-unicode tries to find a font for your characters.
+Also, many people (me included) like large windows and even larger
+scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
+6 bytes per screen cell. For a 160x?? window this amounts to almost a
+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 whether I'm running rxvt-unicode or a regular
+xterm? I need this to decide about setting colours 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 colour.
+=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<pod2xhtml> (from
+F<Pod::Xhtml>). 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

 (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*.
-=item Why C++, isn't that unportable/bloated/uncool?
+=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++.
 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
+in C that use gobs of memory, and 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)
 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 :)
-=item Does it support tabs, can I have a tabbed rxvt-unicode?
-rxvt-unicode does not directly support tabs. It will work fine with
+=head2 Rendering, Font & Look and Feel Issues

-=item How do I know which rxvt-unicode version I'm using?
+=head3 I can't get transparency working, what am I doing wrong?

-=item I am maintaining rxvt-unicode for distribution/OS XXX, any recommendation?
+That works. If you think it doesn't, you lack transparency and tinting
+support, or you are unable to read.
+This method requires that the background-setting program sets the
+_XROOTPMAP_ID or ESETROOT_PMAP_ID property. Compatible programs
+are Esetroot, hsetroot and feh.

-   REMOTE=remotesystem.domain
-   infocmp rxvt-unicode | ssh $REMOTE "cat >/tmp/ti && tic /tmp/ti"
-... or by installing rxvt-unicode normally on the remote system,
-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

-quick-and-dirty workaround for rare cases, though.
-If you always want to do this (and are fine with the consequences) you
-can either recompile rxvt-unicode with the desired TERM value or use a
-resource to set it:

-If you don't plan to use B<rxvt> (quite common...) you could also replace
-the rxvt terminfo file with the rxvt-unicode one.
-=item C<tic> outputs some error when compiling the terminfo entry.
-Most likely it's the empty definition for C<enacs=>. Just replace it by
-C<enacs=\E[0@> and try again.
-=item C<bash>'s readline does not work correctly under @@RXVT_NAME@@.
-=item I need a termcap file entry.
-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>.
-You could use rxvt's termcap entry with resonable results in many cases.
-You can also create a termcap entry by using terminfo's infocmp program
-like this:
-   infocmp -C rxvt-unicode
-Or you could use this termcap entry, generated by the command above:

-=item Why does C<ls> no longer have coloured output?
-The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
-decide wether a terminal has colour, but uses it's own configuration
-file. Needless to say, C<rxvt-unicode> is not in it's default file (among
-with most other terminals supporting colour). Either add:
-   TERM rxvt-unicode
-to C</etc/DIR_COLORS> or simply add:
-   alias ls='ls --color=auto'
-to your C<.profile> or C<.bashrc>.
-=item Why doesn't vim/emacs etc. use the 88 colour mode?
-=item Why doesn't vim/emacs etc. make use of italic?
-=item Why are the secondary screen-related options not working properly?
-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
-I log-in to another system it tells me about missing terminfo data?> on
-how to do this).
-=item 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.
-=item Rxvt-unicode does not seem to understand the selected encoding?
-=item 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.
-Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
-programs. Often rxvt-unicode is started in the C<C> locale, while the
-login script running within the rxvt-unicode window changes the locale to
-something else, e.g. C<en_GB.UTF-8>. Needless to say, this is not going to work.
-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"
-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
-like:
-  locale: Cannot set LC_CTYPE to default locale: ...
-Then the locale you specified is not supported on your system.
-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

+=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
 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
 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

-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.

 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:

+=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.
-=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, 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>.
-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 :)

-=item 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
-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.
-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.
-=item How does rxvt-unicode determine the encoding to use?
-=item Is there an option to switch encodings?
-Unlike some other terminals, rxvt-unicode has no encoding switch, and no
-specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
-UTF-8 or any other encodings with respect to terminal I/O.
-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
-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.
-Unfortunately, there is no system-independent way to select locales, nor
-is there a standard on how locale specifiers will look like.
-On most systems, the content of the C<LC_CTYPE> environment variable
-contains an arbitrary string which corresponds to an already-installed
-locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
-C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
-(i.e. C<de> or C<german>) are also common.
-Rxvt-unicode ignores all other locale categories, and except for
-the encoding, ignores country or language-specific settings,
-i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
-rxvt-unicode.
-If you want to use a specific encoding you have to make sure you start
-rxvt-unicode with the correct C<LC_CTYPE> category.
-=item 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
-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
-   xjdic -js
-   printf '\e]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
-rxvt-unicode-locales.
-=item Can I switch the fonts at runtime?
+=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.
 You can think of this as a kind of manual ISO-2022 switching.

-=item 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
-use your input method. Please note, however, that you will not be able to
-input characters outside C<EUC-JP> in a normal way then, as your input
-method limits you.
-=item 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
-leaks, and Input Methods can avoid some crashes by careful ordering at
-exit time. B<kinput2> (and derived input methods) generally succeeds,
-while B<SCIM> (or similar input methods) fails. In the end, however,
-crashes cannot be completely avoided even if both sides cooperate.
-So the only workaround is not to kill your Input Method Servers.
-=item Rxvt-unicode uses gobs of memory, how can I reduce that?
-Rxvt-unicode tries to obey the rule of not charging you for something you
-don't use. One thing you should try is to configure out all settings that
-you don't need, for example, Xft support is a resource hog by design,
-when used. Compiling it out ensures that no Xft font will be loaded
-accidentally when rxvt-unicode tries to find a font for your characters.
-Also, many people (me included) like large windows and even larger
-scrollback buffers: Without C<--enable-unicode3>, rxvt-unicode will use
-6 bytes per screen cell. For a 160x?? window this amounts to almost a
-kilobyte per line. A scrollback buffer of 10000 lines will then (if full)

+Most fonts do not contain the full range of Unicode, which is

+to display.
+B<rxvt-unicode> makes a best-effort try at finding a replacement

+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

+=head3 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 map
-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

 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.

+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 to the 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.

+   URxvt.throughColor:     #8080f0
+   URxvt.highlightColor:   #f0f0f0
+Some colours. Not sure which ones are being used or even non-defaults, but
+these are in my .Xdefaults. Most notably, they set foreground/background
+to light gray/black, and also make sure that the colour 7 matches the
+default foreground colour.

+   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. That is 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-Ctrl-1> and C<Alt-Ctrl-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 my 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-e: command:\033[3;1605;5t
+   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
+combinations :->
+=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
+specifying resources), make sure you understand whether and why it
+works. If unsure, use the form above.
+=head3 When I log-in to another system it tells me about missing terminfo data?
+The terminal description used by rxvt-unicode is not as widely available
+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
+be done by simply installing rxvt-unicode on the remote system as well
+(in case you have a nice package manager ready), or you can install the
+terminfo database manually like this (with ncurses infocmp. works as
+user and root):
+   REMOTE=remotesystem.domain
+   infocmp rxvt-unicode | ssh $REMOTE "mkdir -p .terminfo && cat >/tmp/ti && tic /tmp/ti"
+One some systems you might need to set C<$TERMINFO> to the full path of
+F<$HOME/.terminfo> for this to work.
+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
+quick-and-dirty workaround for rare cases, though.
+If you always want to do this (and are fine with the consequences) you
+can either recompile rxvt-unicode with the desired TERM value or use a
+resource to set it:
+   URxvt.termName: rxvt
+If you don't plan to use B<rxvt> (quite common...) you could also replace
+the rxvt terminfo file with the rxvt-unicode one and use C<TERM=rxvt>.
+=head3 nano fails with "Error opening terminal: rxvt-unicode"
+This exceptionally confusing and useless error message is printed by nano
+when it can't find the terminfo database. Nothing is wrong with your
+terminal, read the previous answer for a solution.
+=head3 C<tic> outputs some error when compiling the terminfo entry.
+Most likely it's the empty definition for C<enacs=>. Just replace it by
+C<enacs=\E[0@> and try again.
+=head3 C<bash>'s readline does not work correctly under @@URXVT_NAME@@.
+See next entry.
+=head3 I need a termcap file entry.
+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>.
+You could use rxvt's termcap entry with reasonable results in many cases.
+You can also create a termcap entry by using terminfo's infocmp program
+like this:
+   infocmp -C rxvt-unicode
+Or you could use the termcap entry in doc/etc/rxvt-unicode.termcap,
+generated by the command above.
+=head3 Why does C<ls> no longer have coloured output?
+The C<ls> in the GNU coreutils unfortunately doesn't use terminfo to
+decide whether a terminal has colour, but uses its own configuration
+file. Needless to say, C<rxvt-unicode> is not in its default file (among
+with most other terminals supporting colour). Either add:
+   TERM rxvt-unicode
+to C</etc/DIR_COLORS> or simply add:
+   alias ls='ls --color=auto'
+to your C<.profile> or C<.bashrc>.
+=head3 Why doesn't vim/emacs etc. use the 88 colour mode?
+See next entry.
+=head3 Why doesn't vim/emacs etc. make use of italic?
+See next entry.
+=head3 Why are the secondary screen-related options not working properly?
+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
+I log-in to another system it tells me about missing terminfo data?> on
+how to do this).
+=head2 Encoding / Locale / Input Method Issues
+=head3 Rxvt-unicode does not seem to understand the selected encoding?
+See next entry.
+=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.
+Rxvt-unicode must be started with the same C<LC_CTYPE> setting as the
+programs running in it. Often rxvt-unicode is started in the C<C> locale,
+while the login script running within the rxvt-unicode window changes the
+locale to something else, e.g. C<en_GB.UTF-8>. Needless to say, this is
+not going to work, and is the most common cause for problems.
+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 '\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
+like:
+  locale: Cannot set LC_CTYPE to default locale: ...
+Then the locale you specified is not supported on your system.
+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 :(
+=head3 How does rxvt-unicode determine the encoding to use?
+See next entry.
+=head3 Is there an option to switch encodings?
+Unlike some other terminals, rxvt-unicode has no encoding switch, and no
+specific "utf-8" mode, such as xterm. In fact, it doesn't even know about
+UTF-8 or any other encodings with respect to terminal I/O.
+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 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.
+Unfortunately, there is no system-independent way to select locales, nor
+is there a standard on how locale specifiers will look like.
+On most systems, the content of the C<LC_CTYPE> environment variable
+contains an arbitrary string which corresponds to an already-installed
+locale. Common names for locales are C<en_US.UTF-8>, C<de_DE.ISO-8859-15>,
+C<ja_JP.EUC-JP>, i.e. C<language_country.encoding>, but other forms
+(i.e. C<de> or C<german>) are also common.
+Rxvt-unicode ignores all other locale categories, and except for
+the encoding, ignores country or language-specific settings,
+i.e. C<de_DE.UTF-8> and C<ja_JP.UTF-8> are the normally same to
+rxvt-unicode.
+If you want to use a specific encoding you have to make sure you start
+rxvt-unicode with the correct C<LC_CTYPE> category.
+=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 '\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 '\33]701;%s\007' ja_JP.SJIS
+   xjdic -js
+   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
+rxvt-unicode-locales.
+=head3 I have problems getting my input method working.
+Try a search engine, as this is slightly different for every input method server.
+Here is a checklist:
+=over 4
+=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
+method servers are running with this command:
+   xprop -root XIM_SERVERS
+=item
 =back
+=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
+use your input method. Please note, however, that, depending on your Xlib
+version, you may not be able to input characters outside C<EUC-JP> in a
+normal way then, as your input method limits you.
+=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
+leaks, and Input Methods can avoid some crashes by careful ordering at
+exit time. B<kinput2> (and derived input methods) generally succeeds,
+while B<SCIM> (or similar input methods) fails. In the end, however,
+crashes cannot be completely avoided even if both sides cooperate.
+So the only workaround is not to kill your Input Method Servers.
+=head2 Operating Systems / Package Maintaining
+=head3 I am using Debian GNU/Linux and have a problem...
+The Debian GNU/Linux package of rxvt-unicode in sarge contains large
+patches that considerably change the behaviour of rxvt-unicode (but
+unfortunately this notice has been removed). Before reporting a bug to
+the original rxvt-unicode author please download and install the genuine
+version (L<http://software.schmorp.de/pkg/rxvt-unicode.html>) and try to
+reproduce the problem. If you cannot, chances are that the problems are
+specific to Debian GNU/Linux, in which case it should be reported via the
+Debian Bug Tracking System (use C<reportbug> to report the bug).
+For other problems that also affect the Debian package, you can and
+probably should use the Debian BTS, too, because, after all, it's also a
+bug in the Debian version and it serves as a reminder for other users that
+might encounter the same issue.
+=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> and C<perl-ext> resources
+system-wide (except maybe with C<defaults>). This will result in useful
+behaviour. If your distribution aims at low memory, add an empty
+C<perl-ext-common> resource to the app-defaults file. This will keep the
+perl interpreter disabled until the user enables it.
+If you can/want build more binaries, I recommend building a minimal
+one with C<--disable-everything> (very useful) and a maximal one with
+C<--enable-everything> (less useful, it will be very big due to a lot of
+encodings built-in that increase download times and are rarely used).
+=head3 I need to make it setuid/setgid to support utmp/ptys on my OS, is this safe?
+It should be, starting with release 7.1. You are encouraged to properly
+install urxvt with privileges necessary for your OS now.
+When rxvt-unicode detects that it runs setuid or setgid, it will fork
+into a helper process for privileged operations (pty handling on some
+systems, utmp/wtmp/lastlog handling on others) and drop privileges
+immediately. This is much safer than most other terminals that keep
+privileges while running (but is more relevant to urxvt, as it contains
+things as perl interpreters, which might be "helpful" to attackers).
+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.
+=head3 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,
+whether 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 symbol nor
+does it support it. Instead, it uses its own internal representation of
+B<wchar_t>. This is, of course, completely fine with respect to standards.
+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>).
+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

+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
+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.
+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.
+The solution is to upgrade your system or switch to a better one. A
+possibly working workaround is to use a wcwidth implementation like
+http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c

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

 =item --enable-unicode3 (default: off)
+Recommended to stay off unless you really need non-BMP characters.
 Enable direct support for displaying unicode codepoints above
 65535 (the basic multilingual page). This increases storage
 requirements per character from 2 to 4 bytes. X11 fonts do not yet
 support these extra characters, but Xft does.
 Please note that rxvt-unicode can store unicode code points >65535

 This option will also enable storage (but not display) of characters
 beyond plane 0 (>65535) when --enable-unicode3 was not specified.

 but these are not currently used. Bug me if you want these to be used (and
 tell me how these are to be used...).

+SVG, TIFF, GIF, XPM, BMP, ICO, XCF, TGA and AfterStep image XML
+(L<http://www.afterstep.org/visualdoc.php?show=asimagexml>).
+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.

+=item --enable-256-color (default: off)
+Force use of so-called 256 colour mode, to work around buggy applications
+that do not support termcap/terminfo, or simply improve support for
