Made for embedding case-insensitive alphanumeric tags (three-ish character sequences) in QR codes. Needs to remain readable with one-two pixel errors (added or removed) due constraints imposed by QR code specification; don't always have full control over the QR pixels/modules the text is rendered in.

All 90 and 45 degree angles.

Made mainly since I got frustrated by trying to get various fonts to scale down well to very small sizes where you run into anything that's not vertical, horizontal or diagonal quickly gets very tricky to map to a pixel grid. Don't think this font is a solution, but that sure was the inspiration when I started on it - wanted to try make something that scales up/down alright for different displays while not being a pixel font.

Character shapes are partially a bit weird to help with distinguishing between them when rotated, flipped, weathered or otherwise slightly distressed.
