Well at the moment, UnicodeString (the type in FPC 2.3.1) is a UTF-16
type, not a UTF-8 type. So while FPC doesn't have a native UTF8 type,
I'll start implementing the UTF-16 version using UnicodeString type.
UTF8String is not an actual type, but rather just an alias to String
type or AnsiString type. Like you said, the compiler doesn't
distinguishes between those.
I'm not arguing, I'm simply interested in getting the ball rolling
with improved Unicode support. Even if that means only having UTF-16
support at the moment. And with my current FPC knowledge that limits
me to the RTL only, I don't have the knowledge to implement native
UTF-8 types in FPC - that's a job for Florian or somebody else with
better knowledge of compiler internals.
