    When text is rendered by a computer, sometimes characters are
    displayed as “tofu”. They are little boxes to indicate your device
    doesn’t have a font to display the text.
    Google has been developing a font family called Noto, which aims to
    support all languages with a harmonious look and feel. Noto is
    Google’s answer to tofu. The name noto is to convey the idea that
    Google’s goal is to see “no more tofu”.  Noto has multiple styles and
    weights, and freely available to all.
