We do have a serious source file encoding issue, that leads to crumbled special characters on the pages for most strings out of the xwiki-dictionary files. XWiki expects that all files on disk are in UTF-8 encoding.
We setup the project pom-files to use UTF-8 output encoding on build, yet you still need to configure your IDE (eclipse) correctly to ensure that date in subversion is provided in the right encoding.
Please change your eclipse setup as follows: Configure your ide to use the correct encoding. With eclipse, add
-Dfile.encoding=UTF-8in eclipse.ini file (Source: http://maven.apache.org/general.html#special-characters-site )
