Catrinity Font uses OpenType features for ligatures and the placement of diacritical marks. These may not work in all programs. Some programs also offer options to turn these on or off.
Also, the possibility of having colored glyphs in fonts is relatively new, so many programs still show the monochrome fallback glyphs for these.
