Vivliostyle submitted “Current Status of Japanese Typography Using Web Technologies” as a member submission to the World Wide Web Consortium (W3C). This submission shows which feature of W3C Note “Requirements for Japanese Text Layout”(JLREQ) and “EPUB3 Petition of Japanese typesetting” from EBPAJ is covered by which CSS specification and supported by major browsers.
In order to further advance the support of Japanese typography on the Web, it is necessary to understand exactly how far the current Web technology can provide Japanese typography. However, it is not easy even for experts to examine specifications under development and grasp the current state of the evolving browsers. This submission was written as the first step to understand the current situation correctly.
The authors of this submission are Mr. Tatsuo Kobayashi (Scholex), Mr. Shinyu Murakami (Vivliostyle Founder and CTO), Dr. Makoto Murata (Japan Electronic Publishing Association CTO / Vivliostyle technical adviser / International University of Japan), Mr. Shin Niina (Digital Publishing Initiatives Japan CEO), Florian Rivoal (Vivliostyle CTE), Mr. Junichi Yoshii (Kodansha / IDPF director). Mr. Kobayashi is the chairperson of the W3C Japanese layout task force which published JLREQ, while Dr. Murata led the internationalization (including Japanese typography) of EPUB 3.
The member submission is a procedure for a W3C member company to make technical suggestions to W3C. The submissions received by the W3C team will be published on the W3C site. Member submissions from Japan include Compact HTML and XML Japanese profile. Web Forms 2.0 was originally a member submission, and became a basis of HTML 5. However, even if a member submission is published, it does not mean that it was approved by W3C.
The W3C CSS Working Group will have a face-to-face meeting in Tokyo from 18-21 April 2017. This meeting will be an opportunity for dialogue by those interested in Japanese layout and typography and the members of the CSS Working Group who will be gathered there. The submission will be an important topic in this dialogue.
Also, this submission will be explained in an upcoming JEPA seminar “The Past and Future of JLREQ, and CSS Japanese Typography” on 17 March 2017.
Vivliostyle, founded in 2014, develops Vivliostyle Viewer.js, a technology which enables typographical features on par with those found in the printing world to be used on the web. Another product, Vilviostyle Formatter, generates PDF documents from W3C’s HTML and CSS, or from EPUB documents. This is done in close cooperation with the W3C’s CSS Working Group to ensure the necessary extensions to CSS become part of the standard.
