Unicode Version 6.1 was released today (January 31, 2012). This release triggered an update to the Unicode CMap resources for Adobe-Japan1-6 and Adobe-Korea1-2. The updated CMap resources are now available at the CMap Resources open source project that is hosted at Open @ Adobe. Details have been posted.
Given that Unicode has become the de facto encoding for digital text for modern environments, I encourage readers of this blog to explore for themselves what is new in Unicode Version 6.1.
