setfont(8) — Arch manual pages
https://man.archlinux.org/man/setfont.8The setfont command reads a font from the file font.new and loads it into the EGA/VGA character generator, and optionally outputs the previous font. It can also load various mapping tables and output the previous versions. If no args are given (or only the option - N for some number N ), then a default (8x N) font is loaded (see below).
