U+1AE2 "᫢" Combining Minus Sign Above Unicode Character

U+1AE2 "᫢" Combining Minus Sign Above is a diacritical mark used in the Limbu script, a writing system native to the Limbu people of Nepal and northeastern India. This combining character is designed to be placed above certain base letters to modify their inherent vowel sound, specifically indicating the absence of a vowel or a shortened vowel quality. In linguistic terms, it functions similarly to a virama or vowel killer, rendering a consonant as a pure consonant without an inherent vowel, which is crucial for accurately representing the phonological structure of the Limbu language in written form.
