Quality of font rendering varies greatly depending on platform and application. Mac OSX uses a generic rendering algorithm which displays all fonts equally well and completely ignores font hinting. Windows on the other hand only displays well TrueType fonts which have been optimized (hinted) for the screen.
Font rendering is handled by the operating system’s rasterizer. While Apple’s OS X does a great job of rendering all fine details of type on screen, the Windows rasterizer is less refined, so fonts in small sizes don’t look as good as in Mac OS.
TPTQ Arabic webfonts support all languages supported by their print versions. That’s over 200 languages, including those using Cyrillic, Greek and Arabic scripts.
In order to use Arabic fonts, you need to use special versions of InDesign, PhotoShop or Illustrator. These versions are labeled ME (Middle Eastern) and support bi-directional text setting for Arabic, Farsi and Hebrew. The regular version of Adobe CS3 doesnʼt support Arabic text setting.
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.
