The Vedic Extensions block was first encoded in The Unicode Standard version 5.2. Vedic Extensions are discussed in  Chapter 12 South and Central Asia-I: Official Scripts of India in the Devanagari Extended section. Vedic Extensions may be used with many Indic scripts. Unicode Status pages for scripts that use the Vedic Extensions are found here: Bengali, Devanagari, Grantha, Gujarati, Gurmukhi, Kannada, Malayalam, Newa, Oriya, Sharada, Tamil and Telugu.

The script is now encoded in the following blocks:

Subsequent to version 5.2, the following characters have been added to the Vedic Extensions block:
