This Python module implements the Devanāgarī part of ISO 15919, an international standard for the transliteration of Indic scripts to the Latin alphabet. Devanāgarī is the main script used to write languages like Sanskrit, Hindi, Marathi, and Nepali.
The transliteration scheme is described in Tony Stone's Transliteration of Indic scripts: How to use ISO 15919 and Thomas T. Pedersen's Transliteration of Hindi, Marathi & Nepali (pdf). The Unicode character code chart for the Devanāgarī script (pdf) is available on the Unicode homepage.
An ISO 15919 transliteration of all Hindi words distributed with GNU Aspell is available in HTML (865K) and plain text (459K).
