    If you are going to look at the env yourself, rather than using the
    relevant libraries, you must look at more than just LC_CTYPE.

    The progression is:

        LC_ALL overrides LC_CTYPE overrides LANG

    So, first check LC_ALL; if that is not set then check LC_CTYPE; if
    that is also not set check LANG; if that is not set the locale is C.

    That should match the behavior of POSIX compliant libraries.
