Hm. I'm not sure how I could work with a hb_buffer_t if not by replicating its structure in JS first. Or to create a callback for glyph_h_advance_func etc. calls. For these I need to work with the .hh files. Do you see any other solution?

I see. Thanks for the info. Would love to use fonts with morx as well.

I will look into it later for sure, but for now it works fine with a (double) cast (and that actually makes more sense in JS).

Thanks for your help,
