The Adobe-branded Source Han Sans, Source Han Serif, and Source Han Mono, along with the Google-branded Noto Sans CJK and Noto Serif CJK, are open source Pan-CJK typefaces whose OpenType/CFF fonts and CID-based sources are covered under the terms of the SIL Open Font License, Version 1.1 (also see the LICENSE and FAQ).
In the Latest Release of this project you will find three ready-to-install OpenType/CFF Collections—two Mega OTCs and one Ultra OTC—that include 73, 143, or 216 fonts, depending on which of the five typeface families are included.
The Mega and Ultra OTCs include various combinations of the 45-font Source Han Sans Super OTC, the 28-font Source Han Serif Super OTC, the 70-font Source Han Mono Super OTC, and the 45- and 28-font Noto Sans CJK and Noto Serif CJK Super OTCs. The main intent of this particular open source project is to stress-test environments that consume OpenType/CFF Collections, specifically macOS (OS X) Version 10.8 (aka Mountain Lion) or later, iOS 7 or later, Windows 10 Version 1703 (aka Creators Update) or later, flavors of Linux that use fontconfig and FreeType Version 2.5.0.1 or greater, and Adobe CS6 apps or later.
The COMMANDS.txt file provides the command lines that were used to build these Mega OTCs and Ultra OTC. Only the AFDKO sfntedit and otf2otc tools are required.
