Help creating a featural abjad
Hi everyone, as the title suggests, I'm trying to make a featural abjad for one of my languages, Zanti. I've been having trouble doing so, however, mainly because I'm not quite familiar with abjads and it's hard to tell sometimes if what I'm doing is an abjad or an abugida by accident.
For context, I'm trying to make an abjad that has 2 sets of glyphs for every consonant—one set for words that have +ATR and the other for -ATR. Are there any suggestions people have for what's the best way to approach this? Any programs anyone suggests? I currently use GIMP, and I've used FontForge in the past to make a font for one of my other languages, but I could use some help figuring this one out.
