Re: Special Spacing Not Working
Thanks for the explanation! I think I found the problem and fixed it.
Can you confirm: Setting the special spacing group only fails when starting with a fresh font, and before re-starting Kern On. Is that correct? Once you re-start Kern On, all behaviour is as expected, right?

You should definitely not set the left side of the /n to “No kerning” as there are many combinations with /n as the second glyph that require kerning.
I’d strongly advise against using “No kerning” for any letters.

Re: "Expand Kerning" from autokerned masters to models?
Btw you can also try to juggle pairs and values by showing the models in the upright, then copy-pasting them (as text) into the italic, select all, make them models. In order to transfer the values you could shut down Kern On, open an autokerned backup of the Italic master, copy-paste all kerning to...

Re: "Expand Kerning" from autokerned masters to models?
I would like to copy just the model pairs, but set the values resulting from the autokerning process. Agreed, this is simply what should happen if you deselect “Autokern from”. If you deselect “Interpolate master” this is how it already works (I believe) but I need to implement the same principle f...

Re: in-Glyphs kerning not matching output
I assume what is happening is what you also suspect: The pair is too infrequent in the list. This is why it does not end up with the ideal value (as it is generated on-the-fly while Kern On is running). See my explanation in the other thread for more details. As an experiment, you can increase the v...

Re: "Blue Zone" kerning
What you describe is roughly how the class kerning algorithm works. Sticking to your example, let’s assume a certain pair against /adieresis has an ideal value of 50, and /amacron has 60. If 50 is the class kerning value then, if the exception with /amacron is omitted, the deviation is 10. Multiply ...

Re: Create kerning groups for everything
Using class kerning for sparse rows or columns is inefficient in terms of data size: We need 2 bytes per table cell, no matter whether it is used (non-zero) or not. Glyph-glyph pairs need 4 bytes per pair (each option has a certain overhead). So, for rows or columns that contain fewer pairs than rou...

The quick answer is: Don’t worry about the number of kerning pairs. The somewhat longer answer is: Don’t try to make you font pretty under the hood. All that counts is the visible, final rendering. If that looks good then all is good. Try to be rational: What is the issue with a large number of pair...

Re: Lost in models influences
Kern On “links” all models to all autokerned pairs. It does not link any models to each other. Rather, it tries to assemble them all into an autokerning engine. Sometimes it doesn’t manage to “fit them all under one hat”, as we say in German, and it needs to remove one or several models. There is a ...

Yes, Kern On does take into account the zone above the cap height. Looking at your examples, giving V against A+diacritics somewhat looser kerning than VA does not seem unreasonable to me.

Some parts of the code normalize things, and use the x-height as a measure of the “scale” of the font.
