    - [None] when [s] is UTF-8 compliant
    - [Some (line,byte_pos_line,byte_pos_error)] otherwise.
      note: the first error is at the just after the byte located at
            position [byte_pos_error] (that is also just after the byte
            [byte_pos_error-byte_pos_line] of the line number [line]).
