They do? When using one of the other ports, maybe.

I have a vague memory that thereʼs code in the macOS font backend that
will only allow color fonts if explicitly requested, and there being a
good reason for it. Iʼll trawl through my archives.

I understand it perfectly :-)

You'll be telling me next you've not read tr-51 even once.

This is why Eli is the maintainer: he can express these things clearly
and without rancour (I tend to fail at the latter portion, and end up
having to delete what Iʼve written, which I did several times in this

If I were to nitpick, Iʼd drop this hunk:

+where "My New Emoji Font" should be replaced by the actual name of the
+font you want to use.

because to me thatʼs obvious, but itʼs a minor point.
