この記事の目的は、Typekit から提供される「貂明朝」(Ten Mincho) の書体とフォント開発について技術的詳細を説明することにあります。貂明朝は、これまでどんな日本語フォントも到達しなかった領域に足を踏み入れました。貂明朝の書体デザインについての詳細については、Typekit Blog 上の公式アナウンスメント (英語) の方をご覧ください。この長文の技術的な記事よりも、そちらの方に興味を持たれるかもしれません。公式アナウンスメントに述べられているように、この新しい Adobe Originals の和文書体にはユニークな特長が数多くあります。そのため、日本や各国の書体メーカー、タイプデザイナーの方々はこの書体からインスピレーションを受けられることでしょう。

The purpose of this article is to provide technical details of how the Ten Mincho—貂明朝 in Japanese—typeface and its fonts, which are initially being offered as a Typekit exclusive, were developed, and how they boldly go where no Japanese font has gone before. For more details about the Ten Mincho typeface design itself, which is probably much more interesting than this really long and technical article, I encourage you to read the official announcement (日本語) on the Typekit Blog. As stated in the official announcement, this new Adobe Originals Japanese typeface is unique in many ways, and should serve as inspiration for type foundries and typeface designers in Japan and elsewhere.
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.

Earlier this month, I decided to move the Adobe-Japan1-6 character collection specification to the Adobe Type Tools organization on GitHub, which was partly motivated by constantly-changing URLs on our Font Technical Notes page. Another motivation was to make the specification itself easier to maintain. At some point, I will be adding a more complete list of Supplement 7 (aka Adobe-Japan1-7) candidates to its wiki.
To this end, I decided to do the same for the Adobe-CNS1-7 and Adobe-GB1-5 character collection specifications while on vacation in South Dakota. For the former, I also used the opportunity to update the specification to include Supplement 7 (aka Adobe-CNS1-7), by adding its representative glyphs and other details.
So, that’s three down, and one to go.

This is a very brief article whose purpose is to simply state that the Adobe-Japan1-6 character collection specification is now an open source project that is hosted on GitHub as a new repository in the Adobe Type Tools organization.
Most of my morning was consumed by porting the original text from Adobe InDesign to GitHub-flavored Markdown, and, while I was touching the text, I decided to seize the opportunity to make several corrections and updates. The 500-glyphs-per-page representative glyph charts are now in a separate PDF file. I also used the opportunity to update the aj16-kanji.txt datafile, and also added the latest-and-greatest Adobe-Japan1-6 UVS (Unicode Variation Sequence) definition file. All good stuff, I think.
Enjoy!
It is difficult to imagine that it has been over 20 years since a new RO—or Adobe CID-keyed glyph set—was born. Of course, I am referring to the static glyph sets, not the ones based on the special-purpose Adobe-Identity-0 ROS.
“RO” stands for Registry and Ordering, which represent compatibility names or identifiers for CID-keyed glyph sets that are referred to as character collections. Adobe CID-keyed glyph sets are usually referred to as ROSes, with the final “S” being an integer that refers to a specific Supplement. The first Supplement, of course, is 0 (zero).
One of my recent projects is to revitalize and modernize our Korean glyph set, Adobe-Korea1-2 (see Adobe Tech Note #5093), which was last modified on 1998-10-12 by defining Supplement 2 that added only pre-rotated versions of the proportional and half-width glyphs that are referenced by the effectively-deprecated 'vrt2' (Vertical Alternates and Rotation) GSUB feature. Instead of defining a new Supplement, I decided that it would be better to simply define a completely new glyph set for a variety of reasons. The tentative Registry and Ordering names are Adobe and KR (meaning “Adobe-KR”), and unlike other ROSes for which Supplements are defined incrementally, my current plan is to simultaneously define seven Supplements, 0 through 6.

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.

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.
