Use Noto fonts for Indic (Indian language) scripts
This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee.
Summary
Replace the default Lohit fonts for Indic (Indian) languages with Google Noto fonts.

Current status
- Targeted release: Fedora Linux 39
- Last updated: 2023-06-26
- [<will be assigned by the Wrangler> devel thread]
- FESCo issue: <will be assigned by the Wrangler>
- Tracker bug: <will be assigned by the Wrangler>
- Release notes tracker: <will be assigned by the Wrangler>
Detailed Description
Currently the Lohit fonts are installed and used by default for Indian languages (Indic scripts). However the Lohit project is essentially inactive and maintenance mode at best. So we will change the default to Google's Noto fonts, which are available in multiple weights and both Sans and Serif faces, and also as variable fonts. This should provide a more flexible modern maintained set of fonts for Indic scripts.
Feedback
There was some initial discussion on fonts list, etc: https://lists.fedoraproject.org/archives/list/fonts@lists.fedoraproject.org/thread/LEFRXQCTXXRENR3GJW3NERVPGQNMYDZZ/ which was generally positive.
This included:
- comparison screenshots: https://sshil.fedorapeople.org/lohit-vs-noto-comparison.html
- a copr repo for testing: http://copr.fedorainfracloud.org/coprs/sshil/indic-fonts-test
Benefit to Fedora
Wider range of Indic (Indian) fonts will be available by default as variable fonts in both sans and serif faces in various styles of weights.
