Description Simon Sapin 2013-12-02 20:19:38 UTC 
http://url.spec.whatwg.org/#host-parsing

[[
Let host be the result of running utf-8's decoder on the percent decoding of input. 
]]

Percent decoding is defined for "a string using code points in the range U+0000 to U+007F", but there is not guarantee that input does not contain other code points at that point of host parsing.

What happens to non-ASCII code points?
Comment 1 Anne 2013-12-03 13:14:40 UTC 
How do you get non-ASCII there?
Comment 2 Simon Sapin 2013-12-03 13:29:18 UTC 
new URL('http://☃/')
Comment 3 Anne 2013-12-03 13:33:32 UTC 
So one option would be to percent escape during the host name state. But that is not the only entry point to the host parser. Hmm.
Comment 4 Simon Sapin 2013-12-04 19:01:36 UTC 
The host parser should UTF8-percent-encode, just before it percent-decodes in step 3.
