I made a font that mimics the CSE and CE large os font. The current one is intentionally pixelated and looks best at a multiple of 17px size (pt size varies across oses and monitors) without anti-aliasing. I am also working on a smooth version that should look good at any size, but which would render at 17px without anti-aliasing to exactly what the calculator would display. However, it will take much longer to make than the first one. I will probably do other calculator fonts in the future.

Each calculator character in the ti-ascii charset is mapped to at least one unicode character or pair of characters. You can copy from the example to get the correct characters to use, which display as similar as I could manage in other fonts, but you can also use other characters for certain ones, in particular, all the ones used by the Mac TI-Connect Program Editor should work.

Don't these fonts already exist though? Iirc some come when you install ti-connect. They might have been bad though?

The fonts that come with TI-Connect are very different from the OS font, they just happen to contain some of the same characters.

Awesome! They look very true to the original. I recently swapped fonts in my computer C project, because I was using TI's actual font and unsure if it was gonna get me into legal trouble. I should've come here first, because this looks very good!
