    This statement makes clear that you don't understand the rules of
    typesetting text in Fraktur.
    > If a text in Fraktur absolutely requires the "long s", it's only when the original text was already using this "long s".
    This statement is also incorrect.

    The rules when to use long s in Fraktur and when to use round s depend
    on the position of the character within the word in complicated ways.

    The same word, typeset using Antiqua style will not usually have the long s.

    For German, there exist a large number of texts that were typeset in
    both formats, so you can compare for yourself. Even in France, I suspect
    that research libraries would have editions of 19th century German
    classics in both formats.
    > In that case, encode the "long s": The text will render with a "long s" in both "modern" Latin font styles like Bodoni (with a possible fallback to modern "round s" if that font does not have a "long s"), an in "classic" Fraktur font styles (with here also a possible fallback to Fraktur "round s" if the Frakut font forgets the long s in its repertoire of supported glyphs).
    I'm skipping the rest, of your message because you've started from a
    wrong premise and sorting out which bits still apply even after
    accounting for the wrong premise is not something I have time, energy
    and inclination for.
