Purely out of curiosity: Does anyone know why the Latin characters in the newly released Korean and Japanese versions of Noto Sans/Serif are different than the Latin/Greek/Cyrillic versions that have been out for awhile?
The KR/JP Latin characters could be display weights of Source Serif -- lighter, greater contrast.
Seems like a different Latin design for KR/JP is at odds with Google's goal that the fonts "be visually harmonious across multiple languages, with compatible heights and stroke thicknesses."
[Apologies if this is posted in the wrong category. "Font Technology" seemed like the closest fit.]
