Three Down, One To Go…

Posted on October 15, 2017 by Dr. Ken Lunde | Comments (0)

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.

Adobe-Japan1-6 on GitHub

Posted on October 3, 2017 by Dr. Ken Lunde | Comments (0)

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!

A Forthcoming Registry & Ordering: Adobe-KR-6

Posted on October 1, 2017 by Dr. Ken Lunde | Comments (0)

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.
