Web page uses icon fonts which are served from XData. Benjamin's commit forces UTF-8 for all XData contents, which I suppose destroys fonts. I think encoding should be specified somewhere here. Edward, I have a very little time to look through the issue. If you have some time please try to fix it (check which data arrives to the client first)! Thanks!
