Fupcase no longer maps ?ß to itself (bug#11309)

Browse Source 
* test/src/casefiddle-tests.el (casefiddle-tests-char-casing):
(upcase ?ß) now returns ?ẞ (U+7838), partly for technical reasons but
the previous behaviour was arbitrary and arguably less useful.
Correct upcasing of ß is normally SS, which is what Fupcase returns if
given a string, or (for special purposes) ẞ.
