Vedic Sign Nihshvasa at U+1CD3 marks a breath or exhalation-related notation in Vedic recitation texts. It is part of the Vedic Extensions block, a set of specialized signs used to encode accent, pause, and oral-performance details found in Sanskrit Vedic manuscripts and scholarly editions. In practice, this sign appears in digital transcriptions of Vedic chant where the written text needs to preserve more than ordinary Devanagari spelling. “Nihshvasa” means breathing out, so the mark is used by editors and manuscript specialists to record a recitational feature connected with exhalation or breath handling, especially in precise liturgical or phonetic documentation. Its real-world use is narrow but important: critical editions, manuscript catalogues, Indology research, Vedic chanting studies, and Unicode-aware fonts or input tools for Sanskrit scholarship. It is not a general Sanskrit punctuation mark, and readers will mostly encounter it in specialist material rather than in everyday Hindi, Marathi, or modern Devanagari text. The main practical concern is support: many common fonts do not include the full Vedic Extensions repertoire, so this sign may display incorrectly or not at all unless a font designed for Vedic Sanskrit notation is used.
