Kern value for pair does not exists is huge

[Thom]

The value of kerning for a none existing pair is huge.

print F.kerningForPair(F.selectedFontMaster.id, g1.rightKerningKey , g2.leftKerningKey )
9.22337203685e+18

Why?
I would prefer: None

Makes sense. I don’t like to change it in the current version as this will break stuff…

Okay
