Is this really correct? Character and UnicodeScalar are not synonyms. The Character type represents a character made up of one or more Unicode scalars (i.e. an extended grapheme cluster). Is a CharacterSet a set of Unicode-compliant characters that happens to be restricted to those characters each made up of only a single Unicode scalar, or is it meant to be a set of Unicode scalars? My read of the Foundation documentation is that it is the former.
