Thanks for the mention - I should note that there's a rather large update coming soon, with even more of them. :)
There's also a bigger pile of system/bitmap fonts in raw binary format, included with my DOS-based font editor (https://int10h.org/blog/2019/05/fontraption-vga-text-mode-fo...). Perhaps more pertinent to this thread, since the format is natural for embedded systems/direct video chip usage.

They're in some kind of human-readable text format:
