Yeah, this is a problem.  I don't know yet how to solve it.  Something
like the proposed patch seems to be required but it is really
unfortunate since this means it'll not anymore possible to compile all
message catalogs without major preparations.  Currently programs like
rpm simply compile all catalogs in a loop.  This will be impossible
since a specific locale for each catalog has to be set.

One alternative would be to require the catalogs with known problems
(like the SJIS encoded catalogs) to contain a comment line specifying
the charset.  E.g., require the first line to contain

$ charset=SJIS

If no such line is found the C locale data is used.  Otherwise we'll
convert the whole input file using iconv() to UCS-4, work on it, and
convert back before writing it out.

Does this sound acceptable?
