The problem is that you're generating a URL of the form
http://...page?something®...somethingelse, and ® is being interpreted as
the html entity ®, the registered-copyright symbol.
I'd assume that this is a bug of some sort, that the & separator for the query
string shouldn't be participating in any URL-encode operation. But where the
bug is, I don't know. For now, I'd avoid var names that collide with html
entities.
