Note: [1][2]

Arabic Presentation Forms-B is a Unicode block encoding spacing forms of Arabic diacritics, and contextual letter forms. The special codepoint, ZWNBSP is also here, which is used as a Byte Order Mark.

The presentation forms are present only for compatibility with older standards, and are not currently needed for coding text.[3]
