    No. A <S ZWJ S> leaves the interpretation of the ligature to the font
    designer. There is no mechanism which ensures a sequence being
    interpreted as an uppercase-ß. In fact, there may already exist fonts
    which interpret the <S ZWJ S> a beautiful ligature of two capital S,
    which may be appropriate at places where the use of an uppercase-ß
    is not wanted (e.g. because in lowercase, the ß would be wrong at that

    On the other hand, if Unicode would standardize <S ZWJ S> to be
    interpreted as uppercase-ß, it would introduce this letter "through
    the backdoor" together with a change of the semantics of ZWJ. There
    is no need to encode the uppercase-ß otherwise than usual: giving it a
    code point.

    The uppercase-ß is a different character from a ligature of two "S",
    alone by the fact that the sets of the possible glyphs are definitely
    different, even if there may be a small intersection of this sets.

    Like é may be written e if only 7-bit ASCII characters are available.
    This does not prove é and e being glyph variants of the same character.
