cosmic-text already supports ligatures and emojis. Various GUI projects in the Rust space are using cosmic-text in their libraries and applications. Lapce, for example, uses cosmic-text for its text rendering. And many more.
What do you mean by "native support for FiraCode" (just curious)? Does that mean packaged by default? Or does FiraCode require something more than font ligatures?
I meant that I'd like to be able to select it for everything since it's peculiar.
Gnome-terminal doesn't support it and eventually I wonder if cosmic will use something like alacritty or a custom-made terminal
