Is there anything that supports languages other than English - specifically Indian languages. I am writing documentation (book) to be distributed online. I presently use mdbook but markdown does not support anything other than English.

What do you mean by Markdown not supporting other languages? I don't see how it wouldn't support other languages.

Although we're using Asciidoctor (syntax / markup language) with Antora (tooling) ourselves, including with a Chinese translation. It's similar to the Fedora documentation:
