afshany I know a great font that would be perfect for Kagi. It's called Vazir, and it supports both Persian and Arabic simultaneously. The Vazir font is also used in Telegram. You can also check out this site for more options!
afshany afshany I'm going to post an update. Recently, grok.com added the Vazir font for Persian language users. I strongly recommend you review this matter. also it's good to mention that Google Doc supports this font too. It is an open-source font, so I believe there would be no licensing issue. https://github.com/rastikerdar/vazirmatn
