As I understand it, calling

Procedure MyProcedure(S : RawByteString) ;

begin
end;

with

Type
   T = Type Ansistring(850);


Var
   D : T;

begin
   MyProcedure(d)
end;

will not cause any code page conversion. While if it was

Procedure MyProcedure(S : String) ;

Then the compiler would first convert the code page to
DefaultSystemCodePage or CP_ACP
