In some browsers, most notably Firefox, you may see a barely noticeable ‘blink’ (a.k.a. Flash Of Unstyled Content) before the real font loads in. This is a result of Firefox’s handling of the @font-face rule.
Unfortunately, web browsers do not support OpenType layout features (yet). But the Typotheque webfont system generates font files on the fly, and can apply OpenType features directly to the file in the process. This enables us to support true small caps as well as various styles of numerals.
Regular Typotheque fonts support over 100 languages and advanced typographic features such as small caps, different numeral styles, alternative characters and special symbols. Web browsers, however, can access only a small fraction of those characters. Removing these inaccessible features makes the files much smaller, so they download much quicker.
