Barcode fonts have been around for ages. But what's cute about this one is that it can calculate the EAN13 checksum on its own.

It can’t, at least for Code 128? There’s a text field that you enter the text into, and then the start/stop/checksum characters are computed.
It seems like it doesn't do this for Code 128 (possibly because it is variable-width?). It definitely works with EAN13 though - I tried it locally using only the TTF file.
Oh, interesting! I tried it in Word on macOS but didn't get it to work. But it works in the browser (question mark = calculates check digit).
It uses this, which i have no idea what it is :-) https://learn.microsoft.com/en-us/typography/opentype/spec/f...
