Like CSGO, CS2 uses a FontConfig, the difference is that Valve provides a preset file for CS2 that shows how fonts should be replaced.

core\panorama\fonts\conf.d\42-repl-global.conf

We use this advantage.

We only change this file and the first loaded fonts.conf, otherwise fonts installed in the user area under Windows will not be found.
