I=CA=BCm not sure. I don=CA=BCt think we have a (featurep 'xft) or similar,= and parsing system-configuration-features is just icky.

Fonts that are colour fonts but don=CA=BCt get classified as such by fontconfig (such as "Noto Color Emoji") get added to face-ignored-fonts as and when we discover them. Robert
