OKay, so I've modified templates (added accept-charset= to forms plus fixed some attribs around for xml compliance (not all, just what I've seen in the <form> tag)) and the source (req.setCharacterEncoding(encoding);). Not sure how to make a patch, but download template and src dirs tar.bz'ipped here:

I'm not sure if the <form> modifications were strictly necessary, but they won't hurt (I think, he-he-he).
That's not the end of charset problems, anyway. More on this later. I'm going to sleep now.
