Please file a bug at

(and post the url here)
Nothing looks fishy here (except the order):
SELECT hex(a), a, lower(a), hex(lower(a)), charset(lower(a)), collation(lower(a)) FROM f612862 ORDER BY LOWER(a);
+--------+------+----------+---------------+-------------------+---------------------+
| hex(a) | a | lower(a) | hex(lower(a)) | charset(lower(a)) | collation(lower(a)) |
+--------+------+----------+---------------+-------------------+---------------------+
| 6D | m | m | 6D | utf8 | utf8_bin |
| 61 | a | a | 61 | utf8 | utf8_bin |
| 6262 | bb | bb | 6262 | utf8 | utf8_bin |
| 6B6B6B | kkk | kkk | 6B6B6B | utf8 | utf8_bin |
| 7474 | tt | tt | 7474 | utf8 | utf8_bin |
| 7A7A7A | zzz | zzz | 7A7A7A | utf8 | utf8_bin |
+--------+------+----------+---------------+-------------------+---------------------+
That was using 5.6.12.
