  I setup my XWiki 5.1 env to use UTF-8, but in some
situation XWiki damage my international chars (search, tags with int.characters).
 For example:
 I wrote some international text to search field - ( some documents are suggest ), but
after pressing Enter and Search page is load, the characters in search field is replaced:
 example: I wrote : "šiška" to search field and get  "Å¡iÅ¡ka".
 Where I forgot set something? 
You need to configure all your tools in UTF8: database, servlet container and xwiki.
