The Brill is a Unicode font containing most of the characters used to typeset Sanskrit in roman script. It’s based on Baskerville, which has been used widely in typesetting Brill’s books. From the official pamphlet:
It’s plain to see that it blows fonts like Gentium out of the water, though that certainly isn’t saying much. I don’t love The Brill; some of its features evoke Bulmer’s inelegant take on Baskerville, and it lacks breathing space (which was a design requirement, “allowing Brill to reduce its environmental footprint” – like that’s going to happen). Which is just as as well, because The Brill can only be used for non-commercial purposes – i.e., nowhere in a published PDF or in the browsed or printed page without prior written permission.
