Localisation was added in issue 458 and will require the php-intl extension. To make everything work correctly make sure that this is installed first.

php-intl can be installed as follows

• On a debian based system by hitting sudo apt-get install php-intl or by manually enabling the intl extension in your cpanel (if using shared hosting).
• On a wamp install by following the instructions in this post
