The "Hanyo-Denshi" IVD Collection has been registered!

Dr. Ken Lunde

Senior Computer Scientist, CJKV Type Development

I reported in the April 9, 2010 Typblography post that the "Hanyo-Denshi" (汎用電子) IVD Collection was submitted for registration, as PRI 167 (Public Review Issue #167). I am pleased to announce to readers of this blog that the "Hanyo-Denshi" IVD Collection was registered on November 14, 2010, and includes 4,195 IVSes. This represents a great achievement, specifically that it represents the second IVD collection to be successfully registered. The first, of course, was the "Adobe-Japan1" IVD Collection on December 14, 2007.

While I believe that there would have been benefits to sharing IVSes with the "Adobe-Japan1" IVD Collection, because approximately 60% of the "Hanyo-Denshi" IVSes correspond to "Adobe-Japan1" IVSes, in that the IVS pairs represent identical glyphs, it is more important to respect the decision of the "Hanyo-Denshi" IVD Collection registrant to keep them separate.

Still, for the benefit of present and future customers, it is prudent that we build a correspondence table between "Adobe-Japan1" and "Hanyo-Denshi" IVSes. I started this important task on November 21, 2010, by building a preliminary "Hanyo-Denshi" and "Adobe-Japan1" correspondence table that covers 2,550 of the "Hanyo-Denshi" IVD Collection's 4,195 IVSes, which is over 60%, and which I intend to refine in the coming weeks ahead. (Feedback on the preliminary correspondence table is, of course, welcome and encouraged.) One benefit of such a correspondence table is that it allows for fonts to be developed that support both IVD collections, either completely or subsets thereof. Another benefit is that it enables better interoperability between the IVD collections, such as for document conversion tasks. There are many more uses.

In closing, let us congratulate those involved with preparing and submitting the "Hanyo-Denshi" IVD Collection.

"Hanyo-Denshi" (汎用電子)异体字序列集注册颁布了！

Ken Lunde在四月九号的 Typblography blog上介绍了向Unicode组织提交注册"Hanyo-Denshi" (汎用電子)异体字序列集的提案（公示复审号是PRI 167），该提案已于2010年11月14日得以注册成功。Hanyo-Denshi" (汎用電子)异体字序列集合包括4,195个异体字序列，这是即2007年12月4日颁布的第一个名为"Adobe-Japqn"异体字序列集之后，第二个成功注册颁布的异体字序列集。

其中大约有60%的"Hanyo-Denshi" (汎用電子)异体字序列和"Adobe-Japan1″ 异体字序列相同，它们对应于同一个字形，虽然可以分享"Adobe-Japan1″ 异体字序列，但为了尊重"Hanyo-Denshi" (汎用電子)异体字序列的注册者，还是保持了它们各自的独立性。

另外，为了有利于现在和未来的用户的使用，我们正在建立"Adobe-Japan1″ 和"Hanyo-Denshi" 之间的对应表。 Ken于11月21日开始初步构造该表，它包含2,550 个 "Hanyo-Denshi" 异体字序列，覆盖率是60%（Hanyo-Denshi共有4,195 IVSes），他会继续精炼该表（附上草表，欢迎任何关于该表的意见）。 建立该表是为了开发支持两个异体字序列集（全集或其子集）的字库，另外就是能够更好地在两个 异体字序列集集中沟通，比如文档转换的工作，当然还有更多的用处。
