Fontforge and inkscape? I’ve never gone deep in to it before, but an inkscape wiki page does reference export to font forge as an svg

Maybe 10 years ago I tried designing a font in Inkscape. It was possible but more of a gimmick. I then installed Fontforge and very quickly decided I wasn’t going to learn how to use it, didn’t have the bandwidth. But the tools are there. Both methods have a learning curve but I think have enough instruction resources online.
