Blank as I described in my original report where I included the output
of C-u C-x = which does say there's no font available.  Following the 
recipe with point before the added character it looks like this:



with point after the character it looks like this:



On the macport I see tofu which I think is better.

I realize.  I originally report this there because it did previously handle
emoji better on mac but as of Emacs 28, it's NEWS says:

    Emoji composition handling is aligned with upstream.  You may find
    some incompatibilities with the previous versions.

In email, YAMAMOTO Mitsuharu said to me about this:
"I only mentioned composition, but font selection is also affected."

When I confirmed it was not displayed by the NS port either I reported
it here.

So FYI, I think in this area the macport policies are trying to
converge with Emacs' policies, though I don't want to speak for them.
