Hi @Balearica

I'm working with opentype.js and I would absolutely love to be able to write even a basic GPOS table. I saw you mentioned in your comment below that you did this. Any information or pointers would be amazing! If it's solid enough, I may also turn it into a pull request... but at this point I'd go with a hacky solution that I use locally.

opentypejs/opentype.js#112 (comment)

Thank you!

@mattlag As noted in the comment linked, I created a fork of OpenType.js that supports GPOS type 2 lookups (kerning), which is used for generating fonts in my document conversion web application scribeocr.com (repo here). Since writing that I cleaned up the code and created the merge request opentypejs/opentype.js#743. While it has not yet been merged, that fork should be ready to use.

Awesome, that is exactly the kind of pointer I was hoping for :-) Thank you!
