and you are done.

Won't compile when calling RTL functions with var parameters.

I fail to see why RawByteString should do less conversions than using
AnsiString, when porting a Delphi 7 application. Can you give an
example?

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
