BlockKie. This font is based on both "Helvetica" and "Roboto" fonts, and with numerous characters to simply make them more familiar, containing height limit of 16p for most letters, 20x20p limit for CJK/ideographic characters. After downloading it, you can tell me in the comments how was your performance with this "so classic" Sans Serif font! Thanks for downloading :D
