Yes, but we don't need to do any serious research as to what emoji should be supported by what font. Once we find a suitable free font, we should simply mention it in preference (i.e. before) to the other fonts that support the relevant blocks; then Emacs will automatically DTRT given the available fonts. > As to which emoji font we could pick… Sounds like Noto Color Emoji is a good candidate.
