Indeed, it's not about XWiki (which is configured by default for UTF-8) but about Tomcat and Mysql. Tomcat configuration about utf-8 is in the connector. See.<http://struts.apache.org/2.0.6/docs/how-to-support-utf-8-uriencodin… MySQL configuration is in /etc/my.cnf. Here a complete link about character set and collation<http://cameronyule.com/2008/07/configuring-mysql-to-use-utf-8/…8/>. We advise you utf-8 as character set, and utf8_bin as collation. If your tables are already configured with latin1 or something else, you'll need to convert your existing tables. Regards, Guillaume 2013/1/23 Arnaud bourree &lt;arnaud.bourree(a)gmail.com&gt;
