The same problem happens in the case of X'FF' notation: mysql> select hex(_utf8 X'FF'); +------------------+ | hex(_utf8 X'FF') | +------------------+ | FF | +------------------+ 1 row in set (0.00 sec)

Noted in 5.0.52, 5.1.23, 6.0.4 changelogs. A character set introducer followed by a hexadecimal or bit-value literal did not check its argument and could return an ill-formed result for invalid input.
