(directly with wcscmp())
For single byte locales wcsxfrm() and wcscoll() works, but for multibyte
they do just raw binary.

GNU grep and sort will work just fine.
BSD grep not calls setlocale() but even it will be added, BSD grep
have other places where multibyte is not handled proberly. I already
notice two of them: ignore case comparison and word boundary sensing,
perhaps other places exists, I not study the code enough to cach them all.
BSD sort uses upper half of 256 char table on its own purposes so badly
damage both single byte and multibyte locales and of couse not use
wcscoll() at all etc.
