Source Han Sans is a sans-serif gothic typeface family created by Adobe and Google.

[5] The Latin, Greek and Cyrillic characters are taken from the Source Sans Pro family,[5] and adjusted to fit in with Chinese, Japanese and Korean (CJK) text.

[7] Multiple type foundries drew the glyphs for different languages based on the designs: Changzhou Sinotype[8] and Arphic Technology[9] for Chinese, Iwata Corporation [ja] for Japanese,[10] and Sandoll Communications for Korean.

[18] Version 2.002 fixed some bugs, and also moved 4 of the CJK Unified Ideographs Extension G characters to their designated codepoint, with the corresponding 'ccmp' GSUB feature removed.

[24] Source Han Sans version 2.000 introduced at November 2018 added Traditional Chinese (Hong Kong) as Source Han Sans HK/HC, which follows Hong Kong's List of Graphemes of Commonly-Used Chinese Characters,[20] but no plans were announced to support traditional printing press style for Traditional Chinese users in Source Han Sans.

The remaining characters were from Source Han Sans JP fonts with glyph set supporting only Japanese.
