I wasn't clear in my explanation, because I didn't quite
understand the issue.

If the server specifies the URL already encoded using the '%'
style encoding, then the URL arrives unmodified:

http://localhost/bj%F6rn

On the other hand if I specify the URL with a character name
(is this accepted in the specs?), e.g.:

http://localhost/&eacute;

Then the URL will be encoded differently according to whether the
page is ISO-8859-1 or UTF-8 (would this be represensitive of a URL
typed into the address bar as well?):

ISO-8859-1: http://localhost/%E9
utf-8:      http://localhost/%C3%A9

Since the request header does not explicitly specify the page encoding,
unless I missed this, this makes it it difficult to know how to handle
the URL decoding.
