1745604 - Some chars are not encoded in the hostname got from an URL object

Status: RESOLVED INVALID

(Core :: Networking, defect)

Description

[Calixte Denizet (:calixte)]

For example:

new URL("http://www.${.com").hostname

returns "www.${.com" when the same in Chrome returns "www.%24%7B.com".
After reading the specs, my feeling is that Chrome is correct here.

In section-3.2.2, the host can be a reg-name and this one is defined by

reg-name    = *( unreserved / pct-encoded / sub-delims )

and these 3 possibilities don't include chars "$" or "{" which should be then encoded with a percent.

I misread, in fact "$" should be allowed.

We currently parse it just like the reference URL parser for the URL standard.
