I didn't think that's really the same thing, but it's a long time
since I hacked on ispell.  Also, I don't see why Emacs couldn't match
such words the same as ispell.

Anyhow, as I don't know, what does one have to do to create and use a
dictionary for utf-8 text?  I could probably add support for that.

It is only _external_ encodings that are relevant, and perhaps only
utf-8.  [I don't know if spell-checking actually makes sense in the
Oriental languages which typically use the multibyte iso-2022
encodings.]

Note that Emacs could cope now with checking utf-8-encoded text
against a dictionary for an 8-bit character set as long as the text
concerned can be encoded in that set.  The text will be appropriately
encoded when it is sent to the subprocess.  I think that really
requires using Emacs's (multibyte) syntax tables, though.
