The Compress option in the kerning table seems to be behaving a little unexpectedly and causing me some issues.
I have i (dotless) that shares a left have kerning group with n.
All my i accents share the same n kerning group
My f/n pair has no kerning between them, but I made several kerning exception for various f i accent pairs e.g: fí fĭ fî fï fì fī fĩ
On a kerning table Clean up, a value has been added to all my f/n group pairs that before had no kern value (the added value seems to be the lowest kern value of my exceptions).
I would have though that rather adding a kern value where none existed, a zero would be added.
I imaging this will probably cause other kerning issue throughout the font where no value has been previously added but exceptions exist.
Is my process wrong or is this a bug?
