Some pairs are apparently already kerned, like f and T followed by a few letters. However, here is a function that generates all the pairs that should be kerned:

The first letter of each group name (r/l) refers to the left/right edge. The remaining (t/m/b) indicates where that group's glyphs have ink. rd is the special group for glyphs that descend below the baseline on the right, and ld is for j-like characters that reach in under the letter on their left.
