The above query created a field of koi8r charset, not cp1251 Change: CREATE TABLE a (a CHAR(1) CHARACTER SET utf8) Length now means character length, not byte length. The above creates a field that guarantees can store a multibyte value 1 character long. For utf8 the above creates a field that can store 3 bytes.
