This character belongs to the Arabic Extended-B block. The Arabic Extended-B block expands upon the basic Arabic script by including additional characters necessary for writing specific dialects and languages that use the Arabic script. Arabic is not only the liturgical language of Islam, but also the writing system for many languages across the Middle East, Central Asia, and Africa, including Persian (Farsi), Urdu, Pashto, and Kurdish. These extensions address unique sounds and orthographic conventions not present in standard Arabic, helping to accommodate regional variations in how the script is used. The inclusion of these characters in Unicode is crucial for supporting linguistic diversity, as it enables digital representation and communication in minority languages that might otherwise be marginalized. Additionally, the block is important for scholars who study these languages, as it ensures that rare or specialized characters can be preserved and accessed in modern digital formats..
