It is required that you store all your data in Unicode format (UTF-8). New installations must be performed into databases that have their default character set as Unicode. If you are upgrading, you should perform the UTF-8 migration process (see the Admin page).
Installing the optional ICONV library is highly recommended in order to improve site performance, particularly if your site is supporting non-latin languages.
