    Others have posted the right place to look.  However, if you are
dealing with multi-lingual or non-Latin1 text be warned.

    The "correct" mapping for ISO Latin 1, which is what you should
get, may not be what you want.  In particular PC-Compatible machines,
Macintoshes, and Unix machines do not use Latin1 by default.  (The
Amiga I am typing this on does. ;-)

    The multilingual problems can arise either due to use of say
Latin2, or be more subtle.  For instance, the correct upper/lower case
mapping for e-acute in French is locale specific.

    All this is why the facilities for making your own maps are there.
