Why we need to understand OpenType features

Much of the font creator programs offer nowadays simplified ways to create OpenType features. But when the things go wrong these programs could not help us. So we need to understand the structure, the logic and the syntax of the OpenType features.

Please, note that even well written OpenType features could not work. Why? Because the use of OpenType features relies on your applications’ support. Click here to see OpenType features’ support in applications. Check here for the browsers’ support for font-feature-settings.
