Does Dorico support colored fonts? That is, glyphs that include white (non-transparent) elements?
I’m not an expert on colour fonts, but I believe the same basic mechanism is used for emoji and for other coloured glyphs, so to whatever extent emoji are supported, I believe colour fonts will in general be supported. However, I can’t find any specific documentation concerning what Qt actually supports in this regard, so I don’t know what you should be able to rely upon.
Well, if I could produce this abomination in Dorico, they should be supported, I guess?
