To make the webfont files as small as possible, we remove some inaccessible glyphs, and users can specify languages to support. Licensed fonts can use as many as 5 languages, trial licences work with a single language. You can also specify custom sets, and preview the glyph set directly.
Regular Typotheque fonts support over 250 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.
Up-to-date information about languages currently supported by our fonts is here.
