I just spot checked Chrome (Mac and Android), Firefox, and Safari, and
all of them displayed emoji names in URI domain names as A-labels.  If
you want to try it, I have a handy wildcarded link farm.

In all of my browsers, this one displays as three random Chinese


This one is a lock emoji followed by "google" and displays as an A-label.


This one is two piles of poop, also displays as an A-label.


If you want to try other stuff, http://<anything>.web.sp.am will return a
live harmless web page.

Also see this M3AAWG BCP from last year, based on what Google does,
but endorsed by and I believe implemented by other M3AAWG members:
