As discussed on irc today, this is a no go for the rtl. Ansistrings are
encoded in the system encoding, this is a convention everything depends
on like all Ansi* routines in sysutils. I give the bug report "I added
widestringmanager.outputformat := soUTF8; to my program, now
AnsiStrUpper doesn't work anymore", 1-2 weeks. It is fine if projects
break with the convention, but then they have to deal with it by e.g. by
overriding ansi<->wide conversion in the widestring manager.
