U+0870 "ࡰ" Arabic Letter Alef with Attached Fatha Unicode Character

U+0870 "ࡰ" Arabic Letter Alef with Attached Fatha is a specialized orthographic symbol used in certain historical or scholarly contexts of Arabic script, where it represents the long vowel "ā" with the fatha diacritic physically attached to the alef base rather than placed above it as a separate mark. This character belongs to the Arabic Extended-B block, which was added to Unicode to support a range of early Quranic and classical Arabic texts that employ complex ligatures and combined letter-vowel forms for precise phonetic transcription. Because the attached fatha is an unusual typographic variant, this character is rarely found in modern Arabic typography, but it serves to preserve the exact appearance and reading conventions of ancient manuscripts, particularly in editions of the Quran or in academic transliteration systems.
