I decided to try Kern On with my latest typeface. After deleting all the small pairs (less than 5) and cleaning up some garbage (pairs for CALT glyphs) I still have over 7,500 pairs in each master. And the kern values are terrible for many pairs. Going through them one by one in Glyphs would probably take longer than just kerning the typeface in MetricsMachine. How are people dealing with this? Are people just crossing their fingers and hoping that Kern On did a good job?
