TPTQ Arabic fonts are Unicode compliant, so you need to enter your text correctly encoded. An easy way to find out if you have correctly encoded text is to copy-paste a sample of the text into Internet browser, for example into Google search.
PostScript or Type 1 fonts were developed by Adobe in 1985 for use with their PostScript printers. Initially, this font technology was available only from Adobe.
Briefly, OpenType is a font format jointly developed by Adobe and Microsoft in the late 1990ʼs. It came into wider use only after 2000, when Adobe included support for advanced typographic features in their InDesign, PhotoShop, and Illustrator applications.
We offer fonts primarily in OpenType format. OpenType is the only cross-platform format, i.e. the same file will work on both Macintosh and Windows computers.
While all OpenType fonts will work in nearly all existing software, only some applications take full advantage of OpenTypeʼs advanced layout features. Applications such as InDesign, Illustrator, PhotoShop, QuarkXPress 7 (and higher), Word 2010 and Mellel offer these options.
