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).
