I installed all the noto- fonts packages on my archlinux, but it doesn't help. Are the fonts embedded in the binary, by any chance? Do I have to recompile it, and should I configure fonts in some way when I do?

Yeah gossip ships it's own fonts so it doesn't break on the thousands of variations of systems and how they all do fonts differently.
In the main directory there is a fonts/ folder, and in gossip-bin/src/ui/theme/mod.rs the fonts get loaded in font_definitions(). You can try adding your own and then compiling.
