I use LDAP authentication in our instance of XWiki and almost everything works as expected. The one problem I have is LDAP group mapping that fails when group name contains some local special characters i.e. letter ł in Zespoły.
I see in catalina logs that there is some character encoding issue:

The xwiki.cfg is encoded in UTF-8 and this is the related line
xwiki.authentication.ldap.group_mapping=XWiki.TESTTEST=CN=TESTTEST,OU=Zespoły Projektowe,OU=PROJEKTY,DC=companyname,DC=pl
Is there a way around this? Maybe some escape characters or xwiki.cfg encoding?
