Also on Ubuntu. I only really started using it because it is
consistent with C
i.e.
LC_CTYPE=C
LC_CTYPE=C.UTF-8

Actually this was the reason I made the comment about not being able
to detect setlocale error in bash. wanted to use a fallback list of
the locale synonyms.

The primary problem with this test is you need the locales installed.

thoretical plan
1. compile list of destination code sets.
3. some method to auto install codesets.
3. Get Unicode mappings for said code sets.
2. use iconv to generate bash test tables
4. start crying at all the error messages ;(

now locale -m gives charsets.
Any ideas about finding unicode mappings for said charsets?
I've been looking through the iconv code but all seems a bit laborious.
What charsets would make sense to test?
