Our brand font is Noto Sans, which is an open source font made by Google. It's available in many different languages in print and web. However, using it for the web is more difficult as it is not as widely available. Also, given the fact that it is a Google web font, availability in China is restricted. Fortunately there is a proxy that can be used.
