How to do it...

Open the /etc/mysql/my.cnf MySQL configuration file in your favorite editor and ensure that the following settings are set in the [client], [mysql], and [mysqld] sections, as follows:

# /etc/mysql/my.cnf
[client]
default-character-set = utf8

[mysql]
default-character-set = utf8

[mysqld]
collation-server = utf8_unicode_ci
init-connect = ‘SET NAMES utf8’
character-set-server = utf8

If any of the sections don't exist, create them in the file. If the sections do already exist, add these settings to the existing configurations. Then, restart MySQL in your command-line tool, as follows:

$ /etc/init.d/mysql restart
