Hi,
I noticed that every time I use the language filter for a show with a qingle quote in the title, I get a "Bad request" error page.
When I check the url of the error page, I see that the single quote is not correctly "url encoded". Instead of a %27 ther is only a %
If I change that in the url, the page work just fine, so I think there's a small bug, probably one line to fix in the language filter code.
I'm french, so sorry if my english is not very good.
