Yes, certainly. Maybe in 5 years, or 10 years, or in 20 years. But currently,
hardly any font contains the U+1E9E "LATIN CAPITAL LETTER SHARP S" character.
Therefore currently, we should stay with the traditional rule of "ß" -> "SS".

Yes. It is for this reason that
  1. towupper('ß') == 'ß',
  2. a simple loop that calls towupper is *not* the right way to uppercase an
     arbitrary string.

And lowercasing does not work with a simple loop over towlower either, because
of GREEK CAPITAL LETTER SIGMA that needs special treatment.

libunistring is free software: it can be changed to fit particular needs.
