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 characters: http://xn--google.web.sp.am/ This one is a lock emoji followed by "google" and displays as an A-label. http://xn--google-hj64e.web.sp.am/ This one is two piles of poop, also displays as an A-label. http://xn--ls8ha.web.sp.am/ If you want to try other stuff, http://<anything>.web.sp.am will return a live harmless web page.

Thanks Olivier. Interesting indeed... Last night during the party, Don and I tried out emoji domains in different browsers. Browsers on the Mac and iPhone correctly processed the emoji domain name and also showed it correctly. However, when it resolves, the label on top of the browser changes into punycode. Further, if you bookmark an emoji domain, it appears as punycode. If you have several, then it becomes difficult to differentiate between them. However, the above behaviour seems to be common to all IDNs, not just emoji-based domains. In short, this appears to be a general UA problem (not sure though). satish On Tue, Mar 14, 2017 at 5:15 PM, Olivier MJ Crepin-Leblond <ocl@gih.com> wrote:
