I just spent entirely too long trying to figure out why foot doesn't work with the noto color emoji font. Turns out it doesn't support COLRv1 fonts but doesn't alert the user in any way that they'll notice unless they launch the terminal from another terminal. Logs are written to the parent process's stdout/stderr. The foot docs assured me that what I'm doing is right and that it should Just Work™. Alas! It's a known bug.
