MySQL Character Sets and Collations
From HostThyself
Character Sets and Collations are important when storing languages other than English or multiple languages in the database.
Since MySQL AB, the company that produces MySQL, is a Swedish company, the default character set for MySQL had been latin1_swedish_ci historcially.
To set a diferent default character set ad collation, start MySQL with
mysqld --character-set-server=utf8 --collation-server=utf8_general_ci
Or edit /etc/my.cnf and add to the [mysqld] section
character-set-server = utf8
