Document#getURL does not encode query string

To reproduce you can paste the following snippet in a xwiki/1.0 page, save, then go to Space/YourPage?redir

#if($request.redir)
$response.sendRedirect($doc.getURL("view", "test=été"))
#end
$request.test

There's no easy solution to this problem since:

• modifying the behavior of getURL could potentially break a lot of existing code
• there's no way to get the encoding of a request query string
