DS records now withdrawn and domain working again.
He had tried quite a few different public resolvers who all seemed to
work fine, like OpenDNS - not quite sure why they weren't also failing
like Google.

Indeed - it was MY mistake originally - I was *so* wrapped up in the
Emoji thing, I didn't see the wood for the trees.
The main reason for my distraction was that I recent switch an old
system from "libidn" to "libidn2"
"libidn2" is IDNA2008 compliant, so (correctly) blocks converting emojis
from Unicode into punycode, but is happy to convert the other way round.
So you could argue that a resolver that is "fully IDNA2008 compliant"
might block an emoji domain name?
/Personally/, I think emoji domain names are a bit silly, but I don't
think its necessary to ban or block them.
I can sympathise with ICANN not wanting them in the ROOT, but they seem
pretty harmless at the second level - especially as Egyptian Hieroglyphs
are allowed.

This, on the other hand, is a more serious issue.
However, it would be easy for browsers to warn users if the URL is made
from a mixture of different character sets - we did this in a registry
system to trigger a warning for such applications - so I'm not sure why
they haven't done that.
