500+ characters, and 4 stylistic alternates for each letter and number! If you’re using an Adobe product (like Photoshop of Illustrator) make sure that Contextual Alternates is checked off in the Opentype/Charater panel (see this reference image). Even if it looks toggled ON by default, toggle it off and back on, trust me.
By using Furrow with contextual alternates your words will cycle through all four alphabets. Say you type “people” – the second “e” will be different from the first. This is also super useful for double letters (“TT” LL” “ee” etc.) and words with lots of repetition (MISSISSIPPI).
The included webfont kits also provide a demo html page, showing how to utilize contextual alternates with some simple code on the Furrow text: “font-feature-settings:”calt” 1;”
