Hi Alexey,

> Sorry for the slow response, I was on holidays.

I'll start my vacation (in Russia, by the way) on Friday...
Hope to have a -16 by then.

This is what the current draft -16pre says:

   2.  Resolve the |url| string using the process of reference
       resolution defined by [RFC3986].  At this stage the URL is in
       ASCII encoding [RFC0020], even though the decoded components will
       be interpreted in UTF-8 [RFC3629] after step 5, 8 and 9.

I think this should be much clearer.

Grüße, Carsten
