Arabic Presentation Forms-A is a Unicode block encoding contextual forms and ligatures of letter variants needed for Persian, Urdu, Sindhi and Central Asian languages. The presentation forms are present only for compatibility with older standards such as codepage 864 used in DOS, and are typically used in visual and not logical order.[3]
