issue about PosIU()

see the code:

var
rawutf8str: RawUtf8 = '333你abc好33a';
...
writeln(PosI('ABC好',rawutf8str)); // result is 7
writeln(PosIU('ABC好',rawutf8str)); // result is 0, should be 7
synunistr := Utf8ToSynUnicode(rawutf8str);
writeln(Pos('abc好', synunistr)); // result is 5

PosIU() seems failed to find the substr.

Re: issue about PosIU()

This is expected: PosIU() is not the same as PosI().
It is calling GetNextUtf8Upper() which only deals with WinAnsi (code page 1252) characters to deal with the accents appearing in this code page (e.g. é è ê ë e = E).

I just refined the documentation to make it more explicit and avoid such confusion.
