This font is not intended for Optical Character Recognition use.
We needed a free and open source font for the Bitcoin Knots project, so made this ourselves. See below of previous manufacturers of OCR-B fonts and their statements on copyright and licensing.
What we've done so far:
- redraw of all glyphs from scratch, polishing and optimising paths in the process
- added MIT licence to metadata
- added hexadecimal Tonals
- replaced 🪢 with Knots logo
- added ₿ symbol
- added sats symbol
To Do:
- Reduce letter spacing by 10%
- widen thin letters (c, r, t, f, h, x etc) so less gap when they are near each other, reducing the need for kerning (don't want to do that - want to retain monospacing)
- ,.;: etc make thinner... they are still a bit thick, but still a lot better visually than previous versions
-
- reduce size of numbers
- add left and right arrows (now ← ↑ → ↓ all exist)
- update knots logo to new version

The original OCR-B font was design by Adrian for Monotype, to meet the standards of the European Computer Manufacturers Association (ECMA) and later adopted as the ISO 1073-2:1976 (E) standard. However, specific details about the initial license terms applied by Frutiger or Monotype are not explicitly documented in publicly available sources. https://ecma-international.org/wp-content/uploads/ECMA-11_3rd_edition_march_1976.pdf
