+Arabic letters have 4 forms: Isolated, Initial, Medial and Ending. An arabic letter will have one of these forms depending on the letters preceding and succeeding it: For instance take the letter ﺡ : This is the isolated form (i.e. nothing precedes nor succeeds it), if it comes at the start of a syllable it will have the initial form ( ﺣ ). If it ends a syllable it will have the ending form ( ﺢ ) and if it is in the middle of a syllable it will have the medial form ( ﺤ ).  Some even have more complicated ligature forms (such as Lam and Alef together: ﻻ ) . A utf8 arabic string usually only comprises of isolated letters from [Arabic Unicode Block](http://en.wikipedia.org/wiki/Arabic_%28Unicode_block%29). With this library you will transform it to the rendering/presentation form: [Arabic Presentation Forms B](http://en.wikipedia.org/wiki/Arabic_Presentation_Forms-B)
