Ok, that makes sense.  I'm just testing a patch which use the
environment settings internally as you proposed (still keeping UTF-8 the
default for the "C" locale).  So far it works fine, I have just trouble
with SJIS, but that's not something I can easily test.  I'm simply
lacking a real understanding of the SJIS encoding.  Maybe you can look
into that in the next couple of days?  I'll be mostly offline next week
and the week after so there's a lot time for testing ;-)
