Reopening till the fix hits the repo.

Sorry; better now?

BTW, your error detection algo looks pretty useful. Think you could make it available to the Glyphs guys? 😬

Humm. I still see the same problems in https://github.com/CatharsisFonts/Ysabeau/blob/master/fonts/vf/YsabeauRomanVF.ttf

They are aware of it. They said they're also improving their own algorithms.

In theory someone can write a Glyphs plugin for this, but that's beyond me.

Ah, I haven't regenerated the VFs, only the OTFs and TTFs. Aren't you generating your own VFs anyway? I should probably delete the homegrown ones.

behdad commented 1 year ago

No I'm just running on existing VFs.
