emoji domain support

[tycho01]

Description

Non-ascii characters can be represented in domain names using Punycode.
This means there are emoji domains such as 😎🌐.ws, but only few browsers still support actually displaying such domains using the intended characters (such as emoji), rather than as Punycode.

Steps to Reproduce

1. go to 😎🌐.ws
2. realize your address bar isn't showing emoji
3. feel very disappointed

You can also test with i❤️.ws, which does not feature a redirect.

Actual result:

Lacking proper support, the domain falls back to cooldomain.ws.

Expected result:

😎🌐.ws

• Is the issue reproducible on the latest version of Chrome?
