The emoji problem on Mac OS has to do with the system-level drawing function, CGContextShowGlyphsAtPoint, that used at the Cairo layer, at least in the version of Cairo that we're using. That function doesn't support emoji glyphs.
A newer version of Cairo handles emoji glyphs: https://gitlab.freedesktop.org/cairo/cairo/commit/416a0005ab6a2b9a709d05281025e3581d612989?expanded=1 So, I've put "upgrade Cairo" on my todo list.
