: Kerning in FontForge does not seem to have any effect I am trying to add kerning data to my font. I have manually kerned each letter pair in the “Kern Pair Closeup” window, like this:

YEEEES, finally here is the solution, because it was not a problem of empty field for me :


When you generate the font, you have to tick the 'OpenType old kernel mode' option in the Options dialog.
So : click generate, click "option", check that "old mode", generate and that's it ^^
Now it works with LibreOffice and Unity3D, perfect.

You somehow managed to leave the feature field of your lookup empty:



If you change this field’s content to kern, everything should be working as expected.

Explanation: Lookups are controlled with features associated to them. Some of those features are activated by default in most programs and contexts (e.g., kern is activated by default for horizontal text, but not activated for vertical text), others have to be activated by the user (e.g., stylistic sets). Therefore, you want to associate almost every lookup with a feature, otherwise you will not see any effect. (The only exception are lookups that are activated by other lookups.)
