mysql> Select HEX(CHAR(256)),HEX(CHAR(1,0));
+----------------+----------------+
| HEX(CHAR(256)) | HEX(CHAR(1,0)) |
+----------------+----------------+
| 0100           | 0100           |
+----------------+----------------+
1 row in set (0.00 sec)

The above result set shows that CHAR(256) is equivalent to CHAR(1,0).
