There was some discussion about this a week or two ago. Apparently,
glibc has a way to ask what character set a given locale expects,
but there's no such capability in the C standards, so it's not portable.

Since glibc-based systems seem to be the main ones guilty of defaulting
to non-C locales, perhaps it would be Good Enough (TM) to make the check
on glibc, and assume that the user knows what he's doing elsewhere.
Needs thought though.
