WebFonts will work for Hindi Wiki projects, I looked for an article on the Hindi Wikipedia about the Hindi language. Apparently there is no such article; at least there is no interwiki link to the Hindi Wikipedia.
It really amazed me.
As the objective is to have a sizeable article, I copied the article in Hindi about India to the test page on the Hindi portal at translatewiki.net. A similar exercise is needed for all the official languages of India.
We are very much interested in learning how using WebFonts is received by the communities of the associated Wiki projects. Having a sizeable article allows people to test reading and editing in their language with the latest version of the WebFonts software.
