I agree, but [1] depends on [2], because set-fontset-font needs to know the script. Also, Noto Color Emoji has a free license, so it's okay for it to be in fontset.el, but it is not clear to me whether Apple Color Emoji is distributed under a free license. > For [2], I think that was finished, except that Eli then updated Emacs > to the next version of Unicode, and I haven't adjusted yet. "Finished", in the sense that it is in Emacs already? > Iʼll see if I can clean this up this weekend and throw it on a branch. Thanks. FWIW, I think this is good enough to land on master directly, I see no need for a feature branch.
