It's not nearly as easy to fix as the reporter of that bug imagines,
because we don't know the relationship between pg_wchar representation
and the wchar_t representation assumed by the <wctype.h> functions.

In the short term it should work if you can use a single-byte encoding
(koi8r I suppose) and a locale setting compatible with that.
