C-DAC, under the guidance of The Ministry of Electronics and Information Technology (MeitY), and valuable support from the Department of Science and Technology (DST), is leading the development of digital standards for Indian languages to enable their seamless integration with the internet and emerging technologies.

As part of this effort, the “AKSHAR Document” series has been envisaged to define Coded Character Sets and Composition Rules for scheduled Indian languages. The aforesaid draft standard defines the character repertoire for Hindi, ABNF rules for permissible character combinations, and provides a reference implementation for validation.

This document will form the foundation for ensuring consistency, accuracy, and interoperability in the digital processing of Indian scripts across platforms and applications.

The document has been published by the Bureau of Indian Standards (BIS) for public consultation and is open for comments until 21st September, 2025.

The draft may be accessed at the following link:
