You are wrong. The string types in 3.0.x and 3.1 are like this:

TP, Iso, ExtPas, MacPas, FPC, ObjFPC (or below modes with $H-): String =
ShortString
Delphi (or other modes with $H+): String = AnsiString (or more precisely
String(CP_ACP), meaning the system codepage)
Delphi_Unicode (or other modes with $H+ and $modeswitch unicodestring):
String = UnicodeString
