With a cairo build, I think with an XFT build it could not display these color emoji fonts at all. > (I=CA=BCd test it myself, but downloading joypixels > requires signing up, and I=CA=BCm feeling ornery today). Joypixels is not needed, the problem can also be seen with Noto Color Emoji. I reported a new bug for the emoji sequence display problem here: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=3D39799 In gedit, both =E2=80=9CNoto Color Emoji=E2=80=9D *and* =E2=80=9CJoypixels= =E2=80=9D can display most emoji sequences correctly. The latest version of =E2=80=9CJoypixels=E2=80= =9D seems to be slightly more up-to-date and can display a few sequences correctly which cannot yet be displayed correctly using the latest =E2=80=9CNoto Color Emoj= i=E2=80=9D (build from current git master) but this affects only a handful of sequences. Most sequences display correctly in gedit and I think none of the emoji sequences displays correctly in Emacs. --=20 Mike FABIAN =E7=9D=A1=E7=9C=A0=E4=B8=8D=E8=B6=B3=E3=81=AF=E3=81=84=E3=81=84=E4=BB=95=E4= =BA=8B=E3=81=AE=E6=95=B5=E3=81=A0=E3=80=82
