In the context of the Wide_Value attribute, the -- argument is the original attribute argument, and the result is used -- in a call to the corresponding Value attribute function. If the method -- for encoding is a shift-in, shift-out convention, then it is assumed -- that normal (non-wide character) mode holds at the start and end of -- the result string. EM indicates the wide character encoding method. -- Note: in the WCEM_Brackets case, we only use the brackets encoding -- for characters greater than 16#FF#. The lowest index of the returned -- String is equal to S'First. function Wide_Wide_String_To_String (S : Wide_Wide_String; EM : System.WCh_Con.WC_Encoding_Method) return String; -- Same processing, except for Wide_Wide_String end System.WCh_WtS;
