AnsiUpperCase should work when the "Better Unicode Support" is configured.
All UTF8...() functions in LazUTF8 are set as backends for RTL's
Ansi...() functions.

Yes, I can imagine such translation errors can cause problems. I think
this one is a bug in UTF8UpperCase (called by AnsiUpperCase).
I always wondered how it can work when there are many decomposed
characters and language dependent differences.
Please report with a minimal test application.
