And it is already in Unicode as ẞ LATIN CAPITAL LETTER SHARP S U+1E9E. When looking for the lowercase ß
LATIN SMALL LETTER SHARP S U+00DF in a MacOS Character Viewer, it does not give the uppercase version, for some reason.

The equivalence with "ss" shows up ICU Regular Expressions that do case insensitive matching where the cases have different length, so it should do that for the new character to, I gather.
