    Description

      STR_TO_DATE returns NULL with a warning in case of a correct input
      in combination with ucs2, utf16, utf16le, or utf32:

      MySQL [test]> set character_set_connection=ucs2; select str_to_date('2001-01-01','%Y-%m-%d');show warnings;
      		 
      Query OK, 0 rows affected (0.00 sec)
      		 
       
      		 
      +--------------------------------------+
      		 
      | str_to_date('2001-01-01','%Y-%m-%d') |

      | NULL                                 |
      		 
      +--------------------------------------+
      		 
      1 row in set, 1 warning (0.00 sec)

      | Level   | Code | Message                                               |
      		 
      +---------+------+-------------------------------------------------------+
      		 
      | Warning | 1411 | Incorrect datetime value: '' for function str_to_date |
      		 
      +---------+------+-------------------------------------------------------+
      		 
      1 row in set (0.00 sec)

      The expected result is: 2001-01-01.

      Note, MySQL-5.6 demonstrates the same problem.
