How to delete a charater

[LarsThePenguin]

So I wrote a keyboard driver and does anyone have a way
to like clear the screen and re-print it without that last charater
or just like use an ascii char code
heres my code (main.c):

Hey! I was wondering how you did it, since the link is dead. I'm working on keyboard drivers, but I can't detect key presses. I might be able to help if you make the repo public, and it would also help me, so it's a win win!
