I've been trying to use the lib to analyze TTF and OTF fonts to extract names and other data. Works well with static fonts, but I get unpredictable results with variable fonts. An example would be: https://fonts.google.com/specimen/SUSE

I that, and similar, cases several font weights/styles is packaged in a single file. Is this supported in any way that I have missed? Or is it just no-go?
