U+0622 "آ" Arabic Letter Alef with Madda Above Unicode Character

U+0622 "آ" Arabic Letter Alef with Madda Above is a distinct character in the Arabic script, representing the long vowel sound "ā" as in the English word "father." It consists of the base letter alef (ا) combined with a small diacritical madda mark (ٓ) placed above it, which indicates a glottal stop followed by a prolonged vowel. This character is primarily used in Arabic and other languages that employ the Arabic script, such as Persian and Urdu, often at the beginning of words like "آب" (āb, meaning water) in Persian, where it serves to clearly mark the initial long vowel sound.
