Kern On

Do you have any tips/advice when/before using Kern-On for cursive fonts that require an accurate connection between glyphs?

Working with connected scripts should work with Kern On. I personally haven’t tested this very much yet. The workflow should be similar as for unconnected fonts, though. In case you have alternates that should never be kerned on one side then it is probably easiest to use the “No kerning” property there.

Feel free to send me the font in case you are experiencing any problems.

I have done this and it's possible. I've set zero models for the letters that were connected. Sometimes Kern On insisted on trying to kern them, especially init, fina versions of the same glyphs. It took me a while and some headache but in the end it all worked out.
