One our most common customer service questions is ‘how do I get the swash items to show up in Adobe Illustrator.’ To start, it would best to review these tech notes from Adobe which will easily show you where and how to use these extra swash characters in fonts like Agostina. For more information on the actual OpenType format, check out Adobe’s OpenType Page.

Each Adobe application handles OpenType a little different, so check the specific application help docs on how to view the OpenType options, Adobe has all this clearly listed in the documentation.
