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) and OpenType (OTF) fonts. TPTQ Arabic’s system, however, creates both TTF and EOT fonts on the fly, so the CSS code it generates works correctly in all compliant browsers.
