You are invited to look into glibc sources, but I doubt that you'd
find there some ``standard'' implementation.  The implementation of
wide character functions depends on the internal representation of
non-ASCII characters, and the standard doesn't mandate what that
representation is.  So each implementation is non-standard, in this
sense.

Also, the _really_ hard part of adding such functions to the library
is that all the other character-related functions, like isupper,
ispunct, etc., need to know about the non-ASCII characters and support
them as you'd expect.
