When installing Mysql on Ubuntu the default character set is probably latin-1. Since Ubuntu uses UTF-8 for most other things this may be little strange. But it is easy to change.
The Mysql configuration file
/etc/mysql/my.cnf
has a magic line:!includedir /etc/mysql/conf.d/
This will make it include settings on the subdirectory
conf.d
. It's not recommended to change themy.cnf
file directly since it will cause problems when upgrading Ubuntu/Mysql to a new version.Create a new file:
/etc/mysql/conf.d/utf8_charset.cnf
with the following contents:
[mysqld]
default-character-set=utf8
character-set-server=utf8
collation-server=utf8_unicode_ci
skip-character-set-client-handshake
[client]
default-character-set=utf8
Restart mysql and you will have UTF-8 as character set:
$ mysql -u root -p -e 'show variables like "%character%";show variables like "%collation%"';
