+From [[Faidon]]:
+
+Joey,
+Attached is a patch that adds locale support to ikiwiki.
+A suitable locale is choosed in that order:
+1) $config{locale}
+2) $ENV{LC_ALL}
+3) en_US.UTF-8
+4) en_*.UTF-8
+5) *.UTF-8
+5) en_US
+6) en_*
+7) *
+8) POSIX
+(where * == the first item found)
+
+The patch brings the following functionality:
+a) Proper local time, either using a UTF-8 locale or not (by the means
+of a new function decode_locale),
+b) Support for UTF-8 (or ISO-8859-X) filenames in SVN. Before this
+patch, commiting (or even rcs_updating) on repositories with UTF-8
+filenames is impossible.
+
+This is RFC because it has some hard-coded parts: 'locale -a' and
+/usr/share/i18n/SUPPORTED. They obviously work on Debian, but I'm sure
+they won't work on other distros, let along on other operating systems.
+
+Besides that, it's quite a big of a change and I could use some comments
+to make it better :)
