Google have announced Noto:
Noto is Google’s font family that aims to support all the world’s languages. Its design goal is to achieve visual harmonization across languages. Noto fonts are under Apache License 2.0.
The comprehensive set of fonts and some of the tools used in our development are available at noto.googlecode.com.
The page has a neat map to click for languages, where you can choose a subset per nation – for Kenya you can choose from 20 languages; for Australia, a mere three – English, Italian and Traditional Chinese. I’m not surprised there are so few – we barely see any Greek or Vietnamese writing on the streets, but I guess we don’t see much Italian either. Pity there’s not more South East Asian languages in our curricula.
