(After realizing that the retargeting of Adobe-Japan1-7 to include only two glyphs, and with a fairly predictable release date range, exhibited characteristics of a pregnancy, I became inspired to write the text for the Adobe-Japan1-6 is Expecting! article while flying from SJC to ORD on the morning of 2018-07-20. I also prepared the article’s images while in-flight. The passenger sitting next to me was justifiably giving me funny looks. My flight to MSN, which was the final destination to attend my 35th high school class reunion in greater-metropolitan Mount Horeb, was delayed three hours, and this gave me an opportunity to publish the article while still on the ground at ORD.)
What do we know about Japan’s new era name? First and foremost, its announcement is unlikely to occur before 2019-02-25, because doing so would divert attention away from the 30th anniversary of the enthronement, 2019-02-24, but it may occur as late as 2019-05-01, which is the date on which the new era begins. That’s effectively a two-month window of uncertainty.
Interestingly, the date 2019-05-01 takes place not only during UTC #159, which will be hosted by me at Adobe, but also during Japan’s Golden Week (ゴールデンウィーク), which may begin early to prepare for the imperial transition.

What began on 2017-06-23 when I visited Sandoll‘s office in Seoul, which included discussions about developing a new Korean glyph set to replace Adobe-Korea1-2 (if you click the link, the PDF will download) that was last updated nearly 20 years ago, has culminated in the First Public Release of the new Adobe-KR-9 Character Collection. This glyph set went through four drafts—First Draft on 2017-10-01, Second Draft on 2017-12-19, Third Draft on 2018-01-18, and Fourth Draft on 2018-03-02—followed by a Beta Release on 2018-05-15 that included a complete set of data files, a complete set of representative glyphs, two fully-functional example OpenType/CFF fonts, and other collateral materials.
After a little over a year since the idea for this glyph set was born, I am pleased to announce that the First Public Release was issued today. For those who are curious about what changed between the Beta Release and the First Public Release, please reference the Changes Since Earlier Versions section of the specification. The Adobe-KR-9 CMap resources that correspond to the First Public Release are now available in the CMap Resources project. While visiting that project, be sure to download the bookmarked 1,990-page UTF-32.pdf file from the latest release that provides glyph tables for all UTF-32 CMap resources.
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.
Today’s article provides useful details for our relatively small number of customers who author documents with our flagship Creative Cloud apps and make use of CID-keyed OpenType SVG fonts. A rather broadly-deployed CID-keyed OpenType SVG typeface is the open source Source Han Code JP family, whose development details are described in the very first section of this article.
While it is fully possible to build OpenType fonts—CID-keyed or otherwise—that include an 'SVG ' (Scalable Vector Graphics) table, the infrastructure to support them in apps is still maturing. That is the purpose of this article, so please continue reading if the details interest or otherwise affect you.
Per a suggestion by a friend named Leroy, I recently renamed the multiple-style and multiple-family OTCs (OpenType Collections) in this open source repository which includes such OTCs that are based on the Adobe-branded Source Han and Google-branded Noto CJK families. These multiple-style and multiple-family OpenType Collections were described in this article from April of this year. The purpose of this particular article is to introduce better names for them besides Super OTC.
First, some background about Super OTCs…
Shortly after Source Han Sans and Noto Sans CJK were released, I came up with the idea of creating a single OpenType Collection that includes all languages and all weights, and the name Super OTC was coined. This was included in the Version 1.001 update (2014-09-12) as a fourth deployment format for both families, and each one included 28 fonts. These were expanded to 36 fonts when the HW (half-width, ASCII-only) fonts, which covered only the Regular and Bold weights, were added as part of the Version 1.002 update (2015-04-20). Source Han Serif and Noto Serif CJK included a Super OTC in their Version 1.000 release (2017-04-03).
One of my hobbies is apparently to explore various ways to stress-test Adobe products, and the target of today’s article happens to be recent adventures with Adobe InDesign and our Source Han families.
The background is that I produced Unicode-based glyph synopses as part of the Source Han Sans and Source Han Serif releases, but those PDFs show only up to 256 code points per page, and it takes several hundred pages to show their complete Unicode coverage. I also produced single-page PDFs that show all 65,535 glyphs. A Source Han Sans one is available here, and a Source Han Serif one is available here. However, they are not Unicode-based.
At seemingly every opportunity, whether via this blog or during public speaking engagements, I have made it abundantly clear that the Adobe-branded Source Han families share the same glyph set as the corresponding Google-branded Noto CJK families. That is simply because it is true. What requires a bit of explanation, however, is how the two typeface designs—Source Han Sans and Source Han Serif—differ. That is what this particular article is about.
As the Project Architect of these Pan-CJK typeface families, I have my fingers on all of the data that was used during their development, and for preparing each release. I can therefore impart some useful tidbits of information that cannot be found elsewhere.
To take the previous article further—and because I tend to have an urge to stress-test environments—I added two more Super OTCs to the Source Han Super OTC open source project this morning.
The release of Source Han Serif earlier this month, on 2017-04-03, gave me an opportunity to build yet another resource for stress-testing environments, particularly those that consume OpenType/CFF Collections. (This also continues to simplify file management by combining three Super OTCs into a much larger one.)
Early last August, I celebrated the release of Microsoft’s Windows 10 Anniversary Update (Version 1607, and also known as Redstone 1 or RS1), mainly because it represented the very first version of Windows OS to support OpenType/CFF Collections (aka OTCs). Alas, my favorite Source Han Sans—and now Source Han Serif—deployment format, the Super OTC that packs all of the fonts into a single and easy-to-manage font resource, could not be installed.
It seems that not a day goes by that I am not using Adobe InDesign CC.
It is my preferred document-authoring app, whether I am preparing a relatively simple single-page document or one that is much longer and complex.
Besides being the world’s first open source serif-style Pan-CJK typeface families, the Adobe-branded Source Han Serif and the Google-branded Noto Serif CJK also represent the first broad deployment of two highly-complex and related ideographs that are in the process of being encoded. Their glyphs are shown above in all seven weights. Although it may be hard to believe, the fourth line illustrates the simplified version.
Perhaps as a continuation of this article from almost a year ago with a clever image, I’d like to use this opportunity to mention that the AFDKO tx tool is about to get a new and improved CFF subroutinizer.
The tx tool has actually had a CFF subroutinizer for quite some time, since late 2008 or so, which is invoked by using the “+S” command-line option in combination with the “-cff” command-line option, and while it was noticeably faster than the AFDKO makeotf tool’s built-in subroutinizer, there were issues that prevented me from using it, such as recursion depth and the inability to limit the number of local and global subroutines.
Based on my testing thus far—using my trusty 2014 Apple MacBook Pro—the tx tool’s new subroutinizer is over three orders of magnitude faster that the makeotf tool’s built-in one. Yes, over one-thousand times faster! CIDFont resources that once took hours to subroutinize now take mere seconds, and with comparable results both in terms of number of subroutines and reduced CFF size. The 65,535-glyph Source Han Sans CIDFont resources take approximately 30 seconds to become subroutinized CFFs, and the 23,058-glyph Kozuka Gothic Pr6N (小塚ゴシック Pr6N) and Kozuka Mincho Pr6N (小塚明朝 Pr6N) ones take less than 10 seconds each.
Anyway, the next release of AFDKO will include a version of the tx tool that includes this new and improved subroutinizer. Of course, the primary beneficiaries of this new version are those who build OpenType/CFF fonts that include thousands or tens of thousands of glyphs, like me.
In closing, I’d like to draw attention to the open source otfcc project on GitHub, which apparently provides similar CFF subroutinization results, in terms of speed and the end result.
This article is largely a test, but also serves to start the process of resurrecting L2/14-006 (Proposal to add standardized variation sequences for nine characters) for discussion at UTC #151 in early May.
Liang Hai (梁海) brought up this document for discussion at UTC #150 last week, and while I had an opportunity to have it accepted by the UTC, to be included in Unicode Version 10.0 (June, 2017), I decided that it was prudent to instead prepare a revised proposal that is more complete, mainly because L2/14-006 was submitted and discussed prior to the first release of the Adobe-branded Source Han Sans and Google-branded Noto Sans CJK Pan-CJK typeface families. This functionality was implemented in those typeface families via the 'locl' GSUB feature, which requires the text to be language-tagged. In other words, I learned a lot since L2/14-006 was discussed, and prefer to submit a more complete proposal, even if it means waiting for Unicode Version 11.0 (June, 2018).
As recorded on the very first page of Adobe Tech Note #5078, Adobe-Japan1-6 was released on 2004-03-05, and one of the glyphs that was added was CID+20958. According to the Adobe-Japan1-6 ordering file, its glyph name is freedial, and is assigned to the Dingbats FDArray element for the purpose of hinting. Of course, if you look for CID+20958 in Adobe Tech Note #5078, you can find it on the bottom of page 54, immediately to the right of CID+20957 that maps from U+26BD ⚽ SOCCER BALL, though it is blank. This is simply because Adobe does not have the rights to use NTT’s trademarked FreeDial mark. CID+20958 was included in Adobe-Japan1-6 for the benefit of font developers who do have the rights to use this mark, and can thus include the glyph in their fonts.
Please pardon the apparent non-CJK interruption in the form of this particular article, but I wanted to bring to the readership’s attention a new open source project that has a very long history: ehandler.ps.
Unlike the first and second similarly-titled articles that I published last month, this article will focus on a minor efficiency for the combining jamo feature of the Adobe-branded Source Han Sans and Google-branded Noto Sans CJK Pan-CJK typeface families.
To (significantly) expand yesterday’s super exciting article, and in the continued interest of (stress-)testing the extent to which combining jamo works in various browsers—and when being served as a fully-functional webfont via Adobe Typekit—if you click here, you will open a 40MB HTML file that includes all 1,626,875 possible three-character combining jamo sequences (125 leading consonants, 95 vowels, and 137 trailing consonants) rendered using Adobe Clean Han and its 'ljmo' (Leading Jamo Forms), 'vjmo' (Vowel Jamo Forms), and 'tjmo' (Trailing Jamo Forms) GSUB features.
In the interest of testing the extent to which combining jamo works in various browsers—and when being served as a fully-functional webfont via Adobe Typekit—if you click here, you will open a 200K HTML file that includes all 11,875 possible two-character combining jamo sequences (125 leading consonants and 95 vowels) rendered using Adobe Clean Han and its 'ljmo' (Leading Jamo Forms), 'vjmo' (Vowel Jamo Forms), and 'tjmo' (Trailing Jamo Forms) GSUB features.
