That would make sens, if String was an array container for _one_ Unicode=

character subset and nothing else. What a mess if someone pass an UTF-8 =

string to such a casing mapping method (*)=E2=80=A6 don't expect to deco=

after that.

(*) Except if the string is restricted to US-ASCII, in which case, you  =

will not get anything wrong, but just still a pure US-ASCII string, whic=
h  =

is always UTF-8 by definition. Not the same story for ISO-8859-1 strings=
