On the previous Emacs Mac Port versions, Emacs doesn't need to set
the code below to enable Emoji and the UTF-8 environment doesn't affect it.
(set-fontset-font "fontset-default" 'unicode "Apple Color Emoji" nil
'prepend)
Maybe it's a bug on that port, I CC'ed the maintainer Mituharu.

I believe it has.
Currently, I removed the UTF-8 code and set the Apple Color Emoji font for a
temporary solution.
Again, thanks for your help, I learned a lot with your conversation, you're
so kind. ;)
