    Of course it has a casing relationship. It is one of two uppercase
    forms of "ß", the other being "SS".
    One of these ("SS", with good reasons) is the value of Unicode toupper("ß").
    Nevertheless, users or applications may select the other form whenever
    considered appropriate.
    And, of course, the lowercase of uppercase-ß is ß. Therefore, it is
    proposed that the value of tolower(uppercase-ß) will be ß.
    There is no requirement that toupper is the inverse function of tolower.

    when he adheres to the implicit premise that there is no orthography
    than the current "official" German one. This is a false premise, as
    (as the proposal gives evidence) there are a lot of people (past and
    present) who use a variant of the German orthography in which the use
    of an uppercase-ß is correct.
