U+FBBB "﮻" Arabic Symbol Four Dots Below is a typographic sign used in Arabic script to represent a diacritical mark consisting of four dots arranged in a square or diamond pattern beneath a base letter, often employed in specialized orthographies or pedagogical contexts to denote a specific phonetic value or grammatical function that is not covered by standard Arabic diacritics like fatha or kasra. This character belongs to the Arabic Presentation Forms-A block, which contains ligatures and variants designed for compatibility with legacy text encoding, though it is rarely encountered in modern digital writing and is primarily included for historical or scholarly representation of complex vowel or consonant modifications in certain Quranic recitation traditions or Qur'anic annotation systems.
