Vedic Sign Long Anusvara at U+1CEF is a specialist mark used in Vedic text notation to indicate a prolonged or specially recited nasal resonance. It is part of the Vedic Extensions block, which supplies signs needed for accurately encoding traditional Sanskrit recitation marks beyond ordinary Devanagari letters. In practice, it appears in digital editions of the Vedas, chant manuals, philological transcriptions, and scholarly work on Sanskrit phonetics. An anusvara normally marks nasalization, but this sign records a longer nasal element where a recitation tradition distinguishes its duration or sound value. Its main value is not everyday Sanskrit spelling, but faithful preservation of oral-ritual detail in written form. Editors and researchers use it when plain anusvara signs would lose information about how a Vedic passage is meant to be chanted. Because it is a niche Vedic character, it is most often seen in specialized fonts and academic or liturgical text corpora.
