    I believe the STL now has something kinda like this
    too.

    Does it actually come straight from $LANG or does it
    come from the internally cached values parsed from
    $LANG at program initialization? I ask this because
    the Windows code acts in an equivalent manner but of
    course has no $LANG variable. What does this new code
    do on a Windows (or other) system?

    Also remember that the Unix locale can have one more
    field, often in practice it tends to be "@euro" where
    "@" is the field separator and "euro" is the
    "variant".
    This field is a bit vague though ):

    Another thing is that the encoding field does not tell
    us everything we need to know about the encodings
    needed on any particular system. Specifically the
    GUI can use a different encoding and on some non-Unix
    but Unix-like systems, the filesystem may also use
    UTF-8 I believe.

    Good luck!
