I'm with Wichert here.

In most places, we tend to carry around unicode strings internally, and 
only encode on the boundaries, e.g. when the URL is "rendered". I don't 
see why redirect() can't have a sensible and predictable policy for 
unicode strings, making life easier for everyone.

If we think that non-ASCII URLs are illegal, then maybe we should 
validate for that and throw an error. However, I don't think that's the 
case (anymore?). In that case, passing a unicode object to the function 
seems entirely consistent with other places, e.g. when we pass unicode 
to the page template engine or return unicode from a view, which the 
publisher then encodes before it's pushed down to the client.
