Many of the special characters in our typefaces are activated by turning on the appropriate features in your application. For example, you can select a segment of text and convert it to small caps or to superior letters without having to retype it. Or if you activate a ligature feature, it automatically replaces combining letter pairs with ligatures, so in a name like ʻKafkaʼ, the letter combination ʻfkʼ would be recognized and replaced with the ʻfkʼ ligature. Some OpenType substitutions are programmed to work in certain positions – e.g. some special swash or alternate glyph forms automatically appear only at the beginning or at the end of a word. For more in-depth OpenType feature instructions see the Features page, or consult the PDF that came with your downloaded fonts.
