Hey there, > The next question is how to know whether a given hb_font_t supports a given feature?
Apparently you won't need this anymore. If you do however, you can use `hb_ot_layout_language_find_feature`, it has the mentioned the complications, after that you can even issue `hb_ot_layout_feature_get_name_ids` to get name ids fonts provide for the ssXX and cvXX features, have a look at this test, https://github.com/harfbuzz/harfbuzz/blob/a33f238f8888cc969e1e393deda0518fb8dd6b13/test/api/test-ot-name.c#L35-L70 cvXX are apparently newer and can provide even more information so you may like to encourage that in other applications you may have.
