I'd like to use custom characters in a C program I'm writing for MS-DOS, in text mode, but I have no idea how to do so. I'm not finding anything on the internet, probably because I'm not using the correct search words. I'm not sure if these are called custom characters, user defined characters, or what... Can someone point me to the right direction? Is there any tutorial somewhere? Thanks.


Custom font can be loaded to VGA memory after its CRTC registers have been properly set, see VGA Hardware.
