    Do I understand correctly that the special casing table will continue to
    contain the mapping from SHARP S (U+00DF) to "SS" as below:

    # The German es-zed is special--the normal mapping is to SS. # Note: the
    titlecase should never occur in practice. It is equal to
    00DF; 00DF; 0053 0073; 0053 0053; # LATIN SMALL LETTER SHARP S

    when there is now an official uppercase version of SHARP-S?

    I mean: great for stability, but when one runs upper(0xDF) what is the
    correct outcome?
    Will we we need an exception or override property to the special casing

    The current result of upper(0xDF) in SQL is as follows:
    Oracle: "SS"
    SQL Server: 0xDF (still lowercase!)

    will they both have to change?
