Last year I made a new pixelated free typeface for my 2d game. It has Arabic, Persian, and a subset of Latin glyphs enough for English, German and Spanish texts. Inside the repo you'd find makefile to build the font and generate test outputs.
Since it was my first experience designing a typeface ever, I might have made mistakes not known to me. That's why I post this, hoping someone would point them out. Here is the repo
Also in addition to my other comment, it would be nice to add the circumflex, forward/backward accents (even if they're possible just show them before/after the main alphabet in the preview).
Also, ë, ï and why not ÿ to complete the set? :)
okay, after half a year I finally got into it, took some weekends to learn how to use anchors in Fontforge and finally I made a new release with many diacritics with dynamic positioning (generated by Fontforge) including those letters and many more. Here is the link to release which contains the font in three formats and a picture showing some updated symbols. I also redesigned U, and Y. Still needs more work though. https://github.com/mehdisadeghi/Noqte/releases/tag/0.1.0-beta3
