Hey folks, I'm new to programming in general. I would love to get some pointers related to font subsetting, which I believe is the way to embed only the required glyphs to pdf or svg or ps output. More concretely, how would one go about font subsetting for truetype, type3, type42 fonts. (which I believe are different ways to structure fonts, and if I'm not wrong one could delegate this task to fonttools) (also it'd be completely fine if one were to point out any mistake or conceptual problems with what I want to achieve)
The bad news, Apple may not support COLRv1 in a short time
To be honest, their own support for svg in ot is also terrible.
Not supporting <use> increases the font file size and also increases the development cost of open source tools. googlefonts/nanoemoji#266
Does anyone have any recommendations for examples/docs/discussion for practical work on T1 fonts directly in FontTools?
(for context, this is me with working code for ttLib wanting to avoid the need to cycle type-1 fonts through makeotf solely to make them readable. On the plus side, all I do with them is read them; I don't need to build any type-1 binaries...)
