    @summary toUpperCase should upper-case German sharp s correctly even if

             it's the only character in the string. should also uppercase

             all of the 1:M char mappings correctly.  Also it should handle

             Locale specific (lt, tr, and az) uppercasings and supplementary

             characters correctly.
