noto-fonts (Googles Noto fonts)
Noto's goal is to provide a beautiful reading experience for all
It is a free, professionally-designed, open-source collection of fonts
with a harmonious look and feel in multiple weights and styles. All
Noto fonts are published under the SIL Open Font License (OFL) v1.1,
which allows you to copy, modify, and redistribute them if you need to.
Currently, Noto covers all major languages of the world and many others,
including European, African, Middle Eastern, Indic, South and Southeast
Asian, Central Asian, American, and East Asian languages. Several
minority and historical languages are also supported.
Support for Simplified Chinese, Traditional Chinese, Japanese, and
Korean was first added in July 2014.
