U+10EFF "𐻿" Arabic Small Low Word Madda Unicode Character

U+10EFF "𐻿" Arabic Small Low Word Madda is a specialized diacritical mark used in certain historical or scholarly Arabic script contexts to indicate a prolonged vowel sound, specifically a madda, which typically extends the pronunciation of an alif or similar vowel. Unlike the more common Arabic madda that appears above a letter, this character is designed to be positioned at a low vertical alignment relative to the word, often below the baseline, to accommodate specific calligraphic or orthographic conventions in manuscripts or modern typesetting. Its inclusion in Unicode supports accurate digital representation of ancient and religious texts where precise diacritic placement is essential for correct recitation and meaning.
