        SetArg() must also take a char as i/p value.
        Need the bug URL (OOPS!).

        Reviewed by NOBODY (OOPS!).

        Since user can send a single char (e.g 'D') to setArg() with type set as
        CHAR or UCHAR we need to support non-numeric values as well.
        Also if user send a value other than String or Number throw error.

        No new tests (OOPS!).
