MySQL will by default set collation to
If you are seeing errors like (here using the Mysql2 gem on Ruby):
Mysql2::Error: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and (utf8_general_ci,COERCIBLE) for operation ‘like’
Then it would probably be a good idea to use the same collation.
To change the server collation you can add the following under the
[mysqld] section in
character_set_server = utf8 collation_server = utf8_general_ci
Restart the server after this.
Next you need to convert your tables to utf8 (remember to do a mysqldump or similar backup first).
ALTER TABLE tbl_name CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
