Thanks!  But now we have a diverging set of isxxx methods for 8-bit
strings and Unicode.  I really don't know what the equivalent of these
(ispunct, iscntrl, isgraph, isprint) is in Unicode -- maybe MAL or MvL
know?  Unicode also has a wider definition of digits; do we want to
extend isxdigit() for that?  (Probably not, but I'm not sure.)

Someone commented that isxdigit is a poor name.  OTOH it's what C
uses.  I'm not sure what to say.
