I've missed part of this thread.  Was "Fixed" something like:
   function Strip_Non_Alphanumeric (Str: in String) return String is
     Result : String(Str'range);
     Last : Natural := Result'first-1;
   begin
     for i in Str'range loop
       if not Is_In(Str(i), Alphanumeric_Set) then
         Last := Last+1;
         Result(Last) := Str(i);
       end if;
     end loop;
     return Result(Result'first .. Last);
   end Strip_Non_Alphanumeric;
