In T261479: Wikisource: Make it possible to use any installed fonts in ebooks we dropped support for the Mukta fonts because they're not available in the Debian repos. They should be manually installed on both the prod and test servers, because they're used in a few places.
The full list is:
- Mukta
- MuktaMahee
- MuktaMalar
- MuktaVaani
They're open source and available from https://ektype.in/font-family/mukta-16.html
