Style

The font style is inspired by digital displays, but not outdated, with its straight lines and some diagonals, a modernized look, and also a nice differentiation between numbers and characters.

7 Segments

The renderer stores the glyphs as if it were a 7-segment display, thus spending only 1 bit for each line, which is the trick of being so compact.

The 8 bit/segment it is a special line, its size varies, from bottom to top it stops when it hits the first fixed segment G or A There are special characters, which would be x , v and z to differentiate them from all other characters, they have their own internal rendering function, are flagged as segment H without segment G or A
