I can't remember the exact issue but I'm using microtonal accidentals for some projects anyways. Nothing wrong with the Feta font by the way. I just have an illogical preference for SCORE's look so I'm using Scorlatti plus various tweaks to approximate SCORE's slurs and ties. That sometimes causes me a lot of trouble but at the end I get nice results. I will try to share more details about what doesn't work as well as I'd like but my use case is very specific and non standard so I feel bad asking for help since some tweaks go pretty deep and complex.
