Here is below the configuration for UTF-8. Note that this is valid for XWiki 1.0 b5 and above. Easier configuration might be provided for upcoming releases.

XWiki encoding

Change the charset enconding in these XWiki files :

  • web.xml: locate the filter class com.xpn.xwiki.web.SetCharacterEncodingFilter and change it to UTF-8. It should look like this
   <filter-name>Set Character Encoding</filter-name>
  • xwiki.cfg : locate the line containing xwiki.encoding and change it to look like this
xwiki.encoding = UTF-8

HTML encoding

Change the HTML encoding in XWiki through Administration --> Preferences --> Presentation --> HTTP Meta information. 

This is Administration --> Presentation then look for Header --> HTTP Meta Information in more recent XWiki default wikis

Inside this textbox locate the Content-type meta tag and make it look like this, changing the encoding to UTF-8

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

This step is not needed if you have the following. Instead that line can be left alone.

<meta http-equiv="Content-Type" content="text/html; charset=$!xwiki.encoding" />

Hibernate configuration

Add the following lines in the hibernate.cfg.xml file:

<property name="connection.useUnicode">true</property>
<property name="connection.characterEncoding">UTF-8</property>

MySQL configuration

It's common practice that the MySQL configuration file, in *nix systems is located in /etc/mysql/my.cnf

character-set-server = utf8
collation-server = utf8_bin

Servlet Container


echo off
rem set LANG=fr_FR.ISO8859-1
set LANG=en_US.UTF-8
set JETTY_PORT=8080
java %JAVA_OPTS% -Djetty.port=%JETTY_PORT% -Djetty.home=%JETTY_HOME% -Dfile.encoding=UTF-8 -jar %JETTY_HOME%/start.jar

Instead of config system variable LANG you can use JVM properties 


in server startup script.


In order to enable UTF-8 in tomcat, you have to add


to each connector enabled/used in conf/server.xml. For example the non-SSL HTTP Connector should read:

<Connector port="8080" maxHttpHeaderSize="8192"
   maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
   enableLookups="false" redirectPort="8443" acceptCount="100"
   connectionTimeout="20000" disableUploadTimeout="true"

In case you're using AJP to connect Tomcat and httpd, make sure you add this attribute to the AJP connector.


To run xwiki with UTF-8 in Glassfish you will need to recreate the xwiki-enterprise.war file and do a change to the glassfish config. First, in the Administration GUI under Domain => General => Locale enter en_US.UTF-8.

Now you will need to add all the aforementioned changes from this document to the files in the war file, create a new warfile, and deploy that one to you glassfish installations. This is required due to the fact that Glassfish will not accept changes to a deployed web.xml file. So you need to deploy a ready changed web.xml file inside your war file becuase all subsequent changes to the deployed web.xml file in the filesystem are totally ignored.

Create a new directory that we will use as a temporary place to edit our war file

mkdir xwikitmp

Unpack the warfile:

cd xwikitemp;jar xvf ../xwiki-enterprise-web-1.5.war

Edit the files as mentioned in the beginning of this article:

  • wiki.cfg
  • web.xml
  • hibernate.cfg.xml

Now lets create a new warfile which contains all the changes:

jar cvf ../xwiki-enterprise-web-local-1.5.war .

Now you can deploy your new .war file to Glassfish and it will have all the changes in it and wll be correctly deployed.

System config

Add the following variables to your system

LANG = en_US.UTF-8
