@bug 4219630 4304573 4533872 4900935 8042589 8054307
@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.
