          Description

          MariaDB [test]> SELECT QUOTE(CAST(NULL AS CHAR CHARACTER SET utf8)), QUOTE(_ucs2 0x0061), QUOTE(CAST(NULL AS CHAR CHARACTER SET ucs2));

1 row in set (0.00 sec)

          The expected result according to the manual
          for the third column should be a string 'NULL' (four letters),
          similar to the first column.

          For non-NULL values QUOTE seem to work fine for an UCS2 argument,
          as the second column demonstrates.
