+Noto Sans
+
+1. OPEN FONTS PROJECT'S AIMS
+When text is rendered by a computer, sometimes there will be characters in the text that can not be displayed, because no font that supports them is available to the computer. When this occurs, small boxes are shown to represent the characters. We call those small boxes “tofu,” and we want to remove tofu from the Web. This is how the Noto font families got their name.
+
+Noto helps to make the web more beautiful across platforms for all languages. Currently, Noto covers over 30 scripts, and will cover all of Unicode in the future. This is the Sans Latin, Greek and Cyrillic family. It has Regular, Bold, Italic and Bold Italic styles and is hinted. It is derived from Droid, and like Droid it has a serif sister family, Noto Serif.
+
+2. LICENSE AND OPENSOURCE
+We publish our fonts under the terms of the GPL (see GPL.txt) and OFL (OFL.txt)

This does not agree with the license file you added.
