U+0A4B "ੋ" Gurmukhi Vowel Sign Oo Unicode Character

U+0A4B "ੋ" Gurmukhi Vowel Sign Oo is a combining diacritical mark used in the Gurmukhi script, primarily for writing the Punjabi language, to represent the long vowel sound "oo" as in "boot" or "moon". It is placed above the consonant it modifies, combining with the base character to alter its inherent vowel, and it is distinct from the short vowel sign "u" represented by U+0A41. This sign is essential for accurately spelling Punjabi words such as "ਸੋ" (so) or "ਕੋ" (ko), and it operates as a dependent vowel that cannot stand alone in the script without a consonant base.
