Unihan & Moji Jōhō Kiban Project: The Tip of the Iceberg

As evidenced by the very last paragraph of IRG N1964 (aka L2/13-192), which was discussed during IRG #41 that took place in Tōkyō, Japan at the end of 2013, I have been curious as to why many ideographs that are commonly used in Japan lack a UAX #38 kIRG_JSource property value. As suggested by this recent tweet, I have been thinking about this again…

Standardized Variation Sequences—Part 1

This is a brief article to report that the 16 SVSes (Standardized Variation Sequences) for eight full-width punctuation characters—U+3001 、 IDEOGRAPHIC COMMA, U+3002 。 IDEOGRAPHIC FULL STOP, U+FF01 ! FULLWIDTH EXCLAMATION MARK, U+FF0C , FULLWIDTH COMMA, U+FF0C , FULLWIDTH COMMA, U+FF1A : FULLWIDTH COLON, U+FF1B ; FULLWIDTH SEMICOLON & U+FF1F ? FULLWIDTH QUESTION MARK—that I proposed in L2/17-436 were accepted for Unicode Version 12.0 during UTC #154 this week. After reading the Script Ad Hoc group’s comments, I prepared a revised version (L2/17-436R) that provided additional information as a response to the two comments, which included the table that is shown above, and this served as the basis for the discussions.

This all began with a proposal that I submitted four years ago, L2/14-006, which was resurrected as L2/17-056, and finally discussed during UTC #153 during which I received constructive feedback. This prompted me to split the proposal into two parts. The first part proposed the less-controversial SVSes, which are the ones that were accepted. The second part, L2/18-013, proposes the more controversial ones. I am fully expecting to revise the second part before it is discussed during UTC #155, which begins on 2018-04-30.

I would like to use this opportunity to solicit comments and feedback for L2/18-013, which would be taken into account when I revise it. (I also hope to receive feedback from the Script Ad Hoc group prior to UTC #155, which would also be taken into account.)

In closing, the 16 new SVSes should soon appear in The Pipeline.


Adobe-KR-9 Third Draft

This article picks up where the 2017-12-19 article left off, and provides details about the third draft of the forthcoming Adobe-KR-9 character collection that was issued today.

The third draft of the Adobe-KR-9 character collection includes 22,863 glyphs (CIDs 0 through 22862) distributed among ten Supplements. When compared to the second draft, three glyphs were removed, 254 glyphs were added, and the distribution of glyphs among some of the Supplements was changed. Because it is a draft, the details are still subject to change, though I suspect that any changes will be minimal at this point.

UTC #154: SVSes, IDCs, KPS 9566 & Unicode 11.0

The 154th UTC (Unicode Technical Committee) meeting, which starts one week from tomorrow, will have a very interesting agenda for me, based on the latest documents at the end of the 2017 document register, and in the 2018 one.

Standards 102—Silent Corrections

Continuing where my Standards 101 article left off, class is once again in session as Standards 102, and today’s topic is “silent corrections.”

The ultimate focus of this particular article is on the first three pages of WG2 N4008 (2011), Resolution M58.03 of WG2 N4104 (2011), and the Unicode mappings for two ideographs in GB 12052-89 (1989; 信息交换用朝鲜文字编码字符集), a standard from China that is a regional Korean character set. The two ideographs in question are at positions 72-33 and 72-67 in that standard. All of this started when I submitted L2/10-362 (2010), which proposed better source references for 94 ideographs that were appended to the special version of the GB/T 12345-90 (1990; 信息交换用汉字编码字符集―辅助集) standard that was used to compile the URO (Unified Repertoire & Ordering) in Unicode Version 1.1, but which are not actually present in that standard proper. It turns out that these ideographs originated in the GB 12052-89 standard.

But first, let’s briefly discuss the issue of “silent corrections” in standards, particularly in GB standards…
