    Doesn't default full case-folding already have that effect for "ß"?

    Title case is what you use for the first letter when a truly bicameral
    system would start the word in upper case and continue it in lower case.
    Thus the current default full title case of 'ß' is 'Ss', as in Karl
    Pentzlin's Sorbian example. Casing is locale-dependent. Unicode already
    specifies Lithuanian and Turkic casing rules.

    An interesting question is how a user is to customise his system to
    uppercase 'ß' to the new character, or, should the character be rejected
    again, an appropriate string. Will there be an appropriate locale?
