From bugzilla bug 10943¹:
There are several Catalan locale codes which presently can
be used in X11 systems; especially after they were accepted
in belocs-locale-data².
In the following patches, I³ add ca_AD, ca_FR and ca_IT Catalan
locale codes. For instance, without this, using ca_AD (actually
a quite used locale⁴) some applications (eg. Emacs or Skype)
cannot display Catalan diacritic marks as you type them.

//freedesktop.org/bugzilla/show_bug.cgi?id=1544): Adding support for the si_LK (si, sinhala, si_LK, si_LK.UTF-8) locale. Patch by Anuradha Ratnaweera <gnu.slash.linux@gmail.com>.

Adding some of the major indic locales (bn_IN.UTF-8, bn_IN.utf8, gu_IN.UTF-8, gu_IN.utf8, pa_IN.UTF-8, pa_IN.utf8) to X. Patch by Leon Ho <llch@redhat.com>.
Compress all font encodings (Stefan Dirsch).
Fixed warnings.
Turn on forwarding XNSpotLocation event to XIM server in OffTheSpot and Root mode (bugzilla #1580, James Su).
Added another compose key combination for the Euro symbol (Stefan Dirsch).
Added support for UTF-8 in ja_JP, ko_KR and zh_TW locales (Mike Fabian).
Changed default encoding for ru from KOI8-R to ISO8859-5 (Mike Fabian). This is the encoding that is also used by glibc. We may break other libcs - lets see who complains.
Added explanation for DESTDIR to install to a different directory than /.
Added some early bailouts to atiprobe if PCI structure pointer is NULL to prevent sig11.
XV support doesn't depend on 2D acceleration any more. This patch removes this limitation from the NSC driver. This is a patch that I have committed to XFree86 a while ago but never ported over to X.Org. Matthieu Herrb contributed some build fixes.
Fixing SetDPMSTimers() so that DPMS*Time == 0 disables the appropriate timer. This takes advantage of the fact that TimerSet() with a timeout argument 0 behaves like TimerCanel().
Use /dev/xconsole (named pipe) or devpts for system logger (Werner Fink).
Create missing links for backward compatibility to XFree86 (Stefan Dirsch).
Changed comment to mention xorg.
Changed cursor for the 'kill' action from XC_draped_box to XC_Pirate. If you don't like it we can change it back (original author unkown).
Added 'pic' to the man page rendering command pipeline (Werner Fink).
Added missing return value (Stefan Dirsch, Roland Mainz)
