### Stylistic Sets and Character Variants
Iosevka supports accessing all letter variants using OpenType features, including `ss##` for applying a stylistic set, or `cv##` to cherry-pick variants.

Iosevka supports Language-Specific Ligations, which is the ligation set enabled only under certain languages. These ligation sets are assigned to custom feature tags. To use them, you need to turn **off** `calt` and enable the corresponded feature. The feature list is:
