While the finishing touches are being put on Unicode Version 6.3, which will include the 1,002 Standardized Variants that I already mentioned, everything appears to be on track for Unicode Version 7.0, which will be in sync with ISO/IEC 10646:2014 (4th Edition).
Extension E, which adds 5,762 new CJK Unified Ideographs, is on track to be included in Version 7.0. This will bring the total number of CJK Unified Ideographs to a staggering 80,379 characters. I spent part of this morning preparing an updated version of my CJK Unified/Compatibility Ideographs table that provides a glimpse at Unicode Version 7.0.
(Note that neither Unicode Version 7.0 nor ISO/IEC 10646:2014 have been released or published, meaning that implementers should keep this caveat in mind, hence the use of “glimpse” in the title of this article.)
As I described in Part 1, Part 2, and Part 3 of this series, Standardized Variants offer a Normalization-proof representation for the 1,002 CJK Compatibility Ideographs, which are encoded in the BMP, and at the end of Plane 2. These 1,002 Standardized Variants have been approved, and will be included in Unicode Version 6.3. They will, of course, also be included in IS0/IEC 10646.
In an effort to provide to font developers advance support for the Standardized Variants that correspond to glyphs in Adobe’s public ROSes, the next version of AFDKO will include a new version of the Adobe-Japan1_sequences.txt file that appends entries that correspond to 89 of these Standardized Variants, along with Adobe-CNS1_sequences.txt and Adobe-Korea1_sequences.txt files that specify 14 and 270 entries, respectively, that correspond to these Standardized Variants. If you click on the file names, you can download the files and use them immediately. These are used with the AFDKO makeotf tool, and specified as the argument of the “-ci” command-line option.
The Unicode Consortium announced the release of UTR #50, Unicode Vertical Text Layout, today, via Twitter and their blog. Although I was involved in this Unicode Technical Report to some extent, any congratulatory comments should be directed toward its original and current editors, Eric Muller and Koji ISHII (石井宏治), respectively.
