No, but toUpperCase translates "ß" to "SS" because that is the only uppercase that "ß" has. It doesn't work the other way because "SS" can be either "ss" or "ß", depending on the word. This is documented behavior.


FYI ß is just a modern callygraphy (ie. a ligature) of the ancient german "ss". (the first s being a "long s", "ſ" ). It is one of the rare cases where a ligature has actually been accepted as a full letter.

Except that it's actually an "sz" ligature that is now generally accepted as being equivalent to "ss" -- except that in old spelling (still used by many), sometimes it's still "sz".
