Would you be so kind to provide a simple test case for this? :)
function test(a,b: RawByteString): RawByteString;
begin
Result := a+b;
WriteLn(StringCodePage(Result));
end;
var
u: UTF8String;
a: AnsiString;
begin
a := 'äöü';
u := 'üöä';
test(a,u); //CP_ACP
test(u,a); //UTF-8
end;
It looks to me, however, that no conversion occurs at all!
The strings are only concatenated as they are.
Same for a concatenation of (global) RawByteString variables.
This of course were not a desireable implementation :-(
I'm inclined to say "of course", because in your "test" function you are
concatenating two RawByteStrings which - by definition - don't do any
conversion.

Sven
