It works fine in INN (after I fixed the wildmat support in general to
support UTF-8).  Most of the problems with UTF-8 support in [...] you
have to fix to properly support ? anyway, and some edge cases with *.
It's a bit more complicated and rules out some simple implementation
strategies, but it's not horribly difficult.

There's a test suite in INN that's free for anyone to use which tests
wildmat functions including character classes against various UTF-8 cases
and malformed UTF-8.
