Ooooh.  I didn't know about __STDC_ISO_10646__.  On the other hand, I
imagine that relying on __STDC_ISO_10646__ is approximately equivalent
to relying on the existence of iswprint(), portability-wise, so we
don't really gain anything.

To the best of my knowledge, wchar_t between 0 and 255 are not
guaranteed to be equivalent to unsigned char.  Of course, it may be
true in practice.

The correct answer for all of this is probably libicu.  But that would
be another external dependency, and currently a somewhat volatile one,
so I'm not excited about that either.
