The regex code is working with pg_wchar strings, which aren't
necessarily the same representation that the OS' wide-char functions
expect. If we could guarantee compatibility then the above plan
would make sense ...
it seems to me, that is possible for UTF8 encoding. So isalpha() function may be
defined as:
static int
pg_wc_isalpha(pg_wchar c)
{
if ( (c >= 0 && c <= UCHAR_MAX) )
return isalpha((unsigned char) c)
#ifdef HAVE_WCSTOMBS
else if ( GetDatabaseEncoding() == PG_UTF8 )
return iswalpha((wint_t) c)
#endif
return 0;
}
