You need to convert the multibyte stream to widechar stream, and work
with widechars using iswprint.

Yes, currently glibc use ucs4 to represent widechar internally. However
we'd better not to make any assumption when writing a program.

I'd love to see that :).

Then, go ahead make one. It shouldn't be too much different from en_GB, right?
