Authoring HTML: Handling Right-to-left Scripts
Richard Ishida (ed), W3C Technical Report
W3C announced the publication of a Working Group Note on "Authoring HTML: Handling Right-to-left Scripts." The document was produced by members of the Internationalization Core Working Group, part of the W3C Internationalization Activity.
The document provides advice for the use of HTML markup and CSS style sheets to create pages for languages that use right-to-left scripts, such as Arabic, Hebrew, Persian, Thaana, Urdu, etc. It explains how to create content in right-to-left scripts that builds on but goes beyond the Unicode bidirectional algorithm, as well as how to prepare
content for localization into right-to-left scripts.
The specification is intended for all content authors working with HTML and CSS who are working with text in a language that uses a right-to-left script, or whose content will be localized to a language that uses a right-to-left script. The term 'author' is used in the sense of a person that creates content either directly or via a script or program that generates HTML documents.
It provides guidance for developers of HTML that enables support for international deployment. Enabling international deployment is the responsibility of all content authors, not just localization groups or vendors, and is relevant from the very start of development. Ignoring the advice in this document, or relegating it to a later phase in the development process, will only add unnecessary costs and resource issues at a later date. It is assumed that readers of this document are proficient in developing HTML and XHTML pages..."
