    So it would seem, but I think that UNIX under some circumstances,
    though I do not remember which, needs to know that it is ASCII and
    not anything else. But I'll guess, one shall what works best see when
    making a UTF-8 enabled UNIX.

    I'll pass on this one. There are different approaches, mixed
    encodings or single UTF-8, though.
