I normally use w3m but I have w3m/0.3.2+mee-p24-21+moe-1.5.8
installed and can test it with Emacs 21.3 and Mule-UCS.  I'm
almost ignorant for w3mmee, though.

I tried it and saw almost all non-ASCII characters were shown as
question marks.  I think it is useless.  Instead, I tried the
following and got a good result.

cp /usr/local/etc/w3mmee/w3mconfig.utf-8 ‾/.w3mmee/config

Both `w3m-input-coding-system' and `w3m-output-coding-system'
were `ctext' which is the default then.  Furthermore, I
confirmed setting one or both to `utf-8' causes no problem.

Although I'm not well informed of all of those, I know that
question marks being displayed means Emacs cannot recognize them
as valid characters.  On the other hand, that empty boxes are
displayed suggests lack of some fonts.

Probably, a person who is more appropriate than I should answer
your question. ;-)
