set-fontset-font with a TARGET covering the emoji codepoints in
question, I meant. Youʼre right itʼs probably cleaner to do both at
the same time.
Eli> Also, Noto Color Emoji has a free license, so it's okay for it to be

Eli> distributed under a free license.
Itʼs marked 'Copyright Apple 2011-2016' in the macOS font
selector. And Apple appear to be both sensitive and litigious about
it, so probably best not to promote it.

Eli> "Finished", in the sense that it is in Emacs already?
No, finished as in "it works for me on my mac and GNU/Linux boxes" 🙂
As I said, it needs adjusting to the latest Unicode update.
>> Iʼll see if I can clean this up this weekend and throw it on a branch.
Eli> Thanks.
Eli> FWIW, I think this is good enough to land on master directly, I see no
Eli> need for a feature branch.
OK.
