type UTF8String = type ansistring(cp_UTF8)

Are there any other string types with UTF8 encoding in Free Pascal?
As far as I know it can only be this one.
So it should be used for all functions which require
an UTF8 string as parameter, no?
Any other encoding makes no sense (because these
UTF8 functions cannot be used with it).
