	no, wchar_t is not UCS4.  you need to handle wchar_t values as opaque
	(we support a lot more things than Unicode, and there's no standard
	that says wchar_t is UCS4).
	the following program should identify what encodings are supported.

% env LANG=C ./a.out 
locale C is supported
% env LANG=ja_JP.ISO2022-JP ./a.out
locale ja_JP.ISO2022-JP is supported
% env LANG=en_US.UTF-8 ./a.out 
locale en_US.UTF-8 is supported
% env LANG=bogus ./a.out 
locale bogus is not supported


#include <stdio.h>
#include <locale.h>

	if (!getenv("LANG")) {
		fprintf(stderr, "LANG unset\n");

	if (setlocale(LC_ALL, ""))
		fprintf(stderr, "locale %s is supported\n", getenv("LANG"));
		fprintf(stderr, "locale %s is not supported\n", getenv("LANG"));
