Fontkit produces invalid .ttf files?

[AlexandraK]

I was testing the code form the homepage with the subset and it looks like the .ttf file that is produced by it is not loaded by Chrome.

Chromes throws this error:

OTS parsing error: incorrect entrySelector for table directory

I get this as well but I'm trying to make a subset of a woff file.

Glyphr Studio show an error for this file (remove the txt extension).

[Pomax]

do you have a PoC/minimal code that'll generate a bad TTF to test this?

Ahh, I see what's going on. This line computes the "maximum power of 2 <= numtables" incorrectly, invalidating the searchRange and entrySelector values.:
