Fix: create table t1 (a char(10) character set cp1251) SELECT _koi8r'blabla' as a
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.
