It’s a lot of work but that doesn’t mean it’s not worth it. If there is high enough demand I will do it, but the fonts have to be a bit more profitable than they currently are for me to afford too much of my time on them.
Ultimately, tho, my stance is that the more languages I can support, the better! I just have to juggle many projects right now and have to be careful with my energy. Hopefully I can eventually extend them.
