Pedantically yes, but I am sure it would be easier for implementors of
wildmats to use the present definition, which is %xC0-FF 1*(%x80-BF), and
to be able to do so legally.
What is an implementation supposed to do if it meets an "illegal" one?
Issue an error response, or try to match a newsgroup name (whatever) with
the illigal UTF-8 in it (which will fail, presumably).
BTW, has anyone produced a model implementation of wildmats with UTF-8 in
them yet?
