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 TPTQ Arabic 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 TPTQ Arabic 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.
TPTQ Arabic’s font embedding system works with any browser supporting the @font-face rule, so you don’t have to worry about the technical differences between Explorer and other browsers. For the curious and the technically-minded: Internet Explorer supports embedding of EOT (Embedded OpenType) fonts, whereas other browsers use standard TrueType (TTF)...
The @font-face rule is supported by Firefox 3.5, Safari 3.1, Opera 10, Chrome 5 and Internet Explorer 4.0. Our system is thus compatible with more than 98% of all browsers in use. For older browsers you can define a list of default web-safe font stacks.
