"The Arabic presentation forms A (U+FB50 to U+FDFF) and Arabic presentation forms B (U+FE70 to U+FEFF) contain most of the characters with contextual variation as well as the extended characters appropriate for other languages. These effects are better achieved in Unicode by using the zero width joiner and non-joiner, as these presentation forms are **deprecated** in Unicode, and should generally only be used within the internals of text-rendering software, when using Unicode as an intermediate form for conversion between character encodings, or for backwards compatibility with implementations that rely on the hard-coding of glyph forms." http://en.wikipedia.org/wiki/Arabic_alphabet
