Unicode Block - Arabic Extended-B

Arabic Extended-B is a collection of additional Arabic script characters designed to support a wider range of linguistic and scholarly needs, particularly for historical texts, Quranic annotations, and less common dialectal orthographies. It includes letters for early Arabic writings, such as variants of *beh* and *teh*, alongside diacritical marks and signs used in specialized notations like the *sukun* over *alef* or the *shadda* with *fatha* in certain traditions. The block also contains symbols for the Arabic mathematical notation, such as the *Arabic sign sanah* and *Arabic sign misra*, which are used in manuscripts and printed works to denote specific structural elements. By filling gaps left by earlier Arabic encoding blocks, this set enhances the faithful digital representation of diverse Arabic documents, from medieval poetry to contemporary academic literature, without overlapping with main Arabic or Arabic Supplement ranges.
