IRIs consist of Unicode characters. UTF-8 only enters the picture when 
an IRI is converted to a URI.

If you start with a URI *or* IRI, and then append query parameters, you 
always have the choice not to use non-ASCII characters, and to decide 
yourself what character encoding to use before percent-escaping.

Sure, that's not pretty, but it yields both a legal URI and IRI.

Now, that being said, is there anything HTML5 could do so we can get 
closer to a strict UTF-8 world in the future? Such as allowing servers 
to serve document in an encoding != UTF-8, but still get query 
parameters to be consistently encoded in UTF-8?
