Now I'm confused: what do you mean here by "it does"? Does Emacs support that, or does some other program support it? If Emacs, then why did you just tell there was a problem? When I said "I thought HarfBuzz on Cairo already supported that", I meant Emacs that uses HarfBuzz on Cairo. I'm pretty sure we do support color Emoji in that configuration. > > Can you try this with hb-view and see if HarfBuzz produces a single > > glyph/grapheme from this sequence? > > $ hb-view --annotate --font-file=/home/mfabian/.fonts/joypixels-6.6/android/joypixels-android. > ttf --font-size=50 --text="👩🏽" > > looks like: The image looks partial and pixelated. Can you produce PNG or JPEG or some other color image file, and attach it? Anyway, if hb-view produces a single glyph, then I guess we need to debug ftcrfont.c and/or hbfont.c to see why we we produce 2 glyphs in that case.
