vinoman You're welcome. One more thing. Those are two folders with fonts used in X and Wayland graphical sessions.
Fonts used in text virtual terminals - VTs, TTYs, Ctl+Alt+F1,2,3... - are kept by Solus in the /usr/share/consolefonts
folder. They are treated and used completely differently from fonts for GUI, but I assume the OP question wasn't about VT fonts.
