Vedic Extensions

Vedic Extensions is a Unicode block containing characters for representing tones and other vedic symbols in Devanagari and other Indic scripts. Related symbols (also used in many scripts to represent vedic accents) are defined in two other blocks: Devanagari (U+0900–U+097F) and Devanagari Extended (U+A8E0–U+A8FF).
