If the low codes aren't identical to ASCII, then I think
ascii-compatible should be nil, and I think the relevant example to
follow is that of EBCDIC. I'd suggest to construct a map file by
hand, using EBCDIC maps as example, and see if that works.
It didn't, I took the EBCDIC-US map, and replaced the first entry,
<U0000> /x00 NULL (NUL)
with
<U00B7> /x00 MIDDLE DOT
If it doesn't work, we might need to bring Kenichi Handa on board of
the discussion.
If Kenichi Handa can help, that would be very nice -- it isn't a very
important one but it would be useful for me to get this working.

Not UCS-4, but Unicode codepoints (which is the same thing in
practice, but just so we get our terminology right.)
Are you sure? According to the glibc manual (and a quick glance at the
source, glibc/locale/program/charmap.c), the Unicode entry is supposed
to be a UCS-4 name.
