Hi,
System.UriBuilder and System.Net.WebRequest don't handle zone id part of URIs
correctly.

When creating an URI with System.UriBuilder where the host string is something
like "XXXX::XXXX:XXXX:XXXX:XXXX%Y" (note the %Y!) ToString() will double-escape
the % to %25 which makes the resulting completely invalid.

Then System.Net.WebRequest.Create() with an URI that contains a IPv6 address
and zone id part simply won't work, even if the operation system itself
supports it.

Good news is, that at least IPAddress.ToString() correctly outputs the zone id
:)
