What do you mean by "display these fonts properly"?  The characters
will be displayed on any platform, in their text representation, but
AFAIK Emacs doesn't take color information from the font; the color is
determined by the color attributes of the face.  We also don't support
emoji modifiers and emoji variation selectors.

Really, for keeping up with these developments, we'd need to recruit
at least one person who is expert in this area, and can develop Emacs
capabilities related to latest versions of the Unicode standard.  We
don't have such a person on board at this time.
