This article gives a high level summary of various typographic strategies for fully justifying text on a line and in a paragraph for a variety of scripts, and offers some advice to authors and implementers.

The section about SE Asian justification was rewritten as South & Southeast Asian Writing Systems, adding more detail, and shows examples for Tamil of inter-glyph stretching (as opposed to inter-character).

Until now, only Gecko browsers (eg. Firefox) provided support for CSS counter styles, but an update of Blink last week brought very welcome support to a much wider range of users (via browsers such as Chrome and Edge, etc.).

To coincide with this release, the Internationalization WG updated the WG Note Ready-made Counter Styles. This contains templates for counter styles used by various cultures around the world. It can be used as a reference for those wishing to add user-defined counter styles to their CSS style sheets.

The changes include the addition of new styles for scripts including adlam, hanifi-rohingya, lepcha, meetei, santali, ethiopic and chinese. Instructions were also added for those wanting to use different suffixes or prefixes, according to the context in which the counter style is used.

CSS defines the typographic character unit as a basic unit of text for use with editing operations, however the meaning of that term can vary according to the operation, and there are issues in working with such units in complex scripts. In this article we look at examples of some of those differences and issues.

The W3C Internationalization Activity has just published First Public Working Drafts for 21 documents that explore gaps in language support on the Worldwide Web. Some of these documents are from individual contributors, whereas others are the result of work in a language enablement task force. The list below points to the location of the FPWD and also to the relevant group home page or to the relevant GitHub repository where the work was done.

We are looking for expert contributors who can help us move this work forward by answering questions, documenting gaps in support, and creating tests. For more information about the program, see this 15 minute overview (slides).
