U+0A51 "ੑ" Gurmukhi Sign Udaat Unicode Character

U+0A51 "ੑ" Gurmukhi Sign Udaat is a combining diacritical mark used in the Gurmukhi script, primarily in older or more traditional texts of the Punjabi language to denote a specific tone or stress on a syllable, particularly associated with the high-rising tone sometimes called "Udaat" or "Udat." Unlike more common Gurmukhi vowel signs or consonants, this sign is placed above a character to modify its pronunciation, and its usage has largely diminished in modern standardized Gurmukhi orthography, making it a point of interest for scholars studying historical phonetics and textual traditions within Sikh scriptures and classical Punjabi literature.
