New to Typophile? Accounts are free, and easy to set up.
I'm putting together an OpenType font with a lot of glyphs. Extended Latin, Small Caps, OS and Proportional Figures. I have the class kerning worked out to my satisfaction and my VFB file has 1,061 pairs.
After I generate the OTF and open that back up in FL, the kerning pairs have ballooned to 22,445. And I see that several of my kerning classes have disappeared.
Is this typical? I don't see anywhere in the options where I asked FL to expand or flatten the kerning.
What is happening to my carefully organized classes?
