utf-8 encoding

I'm trying to get xwiki/utf-8/postgres working and ran into a couple of snags. I added some comments to http://www.xwiki.org/xwiki/bin/view/Dev/ CharactersSets In there I mentioned that it should be safe to not set the content length on the response as the http protocol (1.1 anyway) defaults to using chunked encoding if there is no content length set. This way you get the performance benefits of keepalive, without setting the content length. The code should probably be changed in the repository to remove this line, or at the very least have a xwiki.cfg setting for it. Comments? Matt
