While all this may make sense, I'm missing some more reasoning
behind the differences between X.org and glibc.
This change also looks strange:
- 'ka_ge': 'ka_GE.GEORGIAN-ACADEMY',
+ 'ka_ge': 'ka_GE.GEORGIAN_PS',
'ka_ge.georgianacademy': 'ka_GE.GEORGIAN-ACADEMY',
'ka_ge.georgianps': 'ka_GE.GEORGIAN-PS',
'ka_ge.georgianrs': 'ka_GE.GEORGIAN-ACADEMY',
Why is GEORGIAN_PS written with an underscore whereas the other
mappings use dashes ?
Or this one:
- 'fi_fi': 'fi_FI.ISO8859-15',
+ 'fi_fi': 'fi_FI.ISO8859-1',
Why would a locale switch away from an encoding having
the Euro sign to one without it ?
Or why is this latin variant removed:
- 'nan_tw@latin': 'nan_TW.UTF-8@latin',
Why should Russians switch back to ISO ?
- 'ru_ru': 'ru_RU.UTF-8',
+ 'ru_ru': 'ru_RU.ISO8859-5',
or from ISO to KOI ?
- 'russian': 'ru_RU.ISO8859-5',
+ 'russian': 'ru_RU.KOI8-R',
The more I look at these changes, the more I believe we
should not simply take everything we find in the files
for granted. They obviously both have bugs.

It's not a table of exceptions, it's a table mapping commonly
used locale settings to ones which the lib C understands :-)
But regardless, I checked the code and it is already
smart enough to convert lib C incompatible spellings such
as "utf8" to "UTF-8", so these entries can indeed be
removed, but only if the locale is otherwise listed.
In some cases, it's probably better to drop the ".utf8"
to have more generic mappings, e.g.
+ 'bhb_in.utf8': 'bhb_IN.UTF-8',
or
'de_li.utf8': 'de_LI.UTF-8',
though I'd expect that mapping to be:
'de_li': 'de_LI.ISO8859-1',
as for all other "de" entries.
