Kerning pair compile warning

K Cerulean Pease

My kerning information keeps building incomplete, and the key has got to be this warning I get when I compile OT. It repeats for what appears to be every kerning class. What does it mean? Another symptom is that when I "Paste Special" all the kerning information in the glyphs from one font to another, only about half appear in the destination.

Sometimes I get this warning with one font of a family but not the other. The classes in the fonts are the same, the encodings are the same, and the same glyphs exist in each font. Very weird.

You should try to avoid mixing glyphs from different scripts, in this case Latin, Cyrillic and Greek, in kerning classes. Divide your classes by script (Expand class kerning, reorganize classes, compress kerning classes) and see if the warning goes away.

Oh, and delete any kern pairs between glyphs of different scripts that may result when expanding your classes.
