The Internationalization Activity published Text-to-Speech Rendering of Electronic Documents Containing Ruby: User Requirements as a First Public Draft Note.

This document describes user requirements related to text-to-speech rendering of electronic documents containing ruby annotations.

The article How to make list markers stand upright in vertical text has been published.

In Chinese, Japanese, Korean, and Mongolian vertically-set text it is normal for list counters to sit upright above the start of the list. Until recently this was problematic, because browsers would only show the numbers lying on their side. This article describes how to make them stand upright, and the currently remaining issues to make this look perfect.

The documents related to language enablement at the W3C continue and expand the work to reorganise information to represent scripts, rather than individual languages. The newly published -lreq documents should be a first port of call for information related to a given script. They point to descriptions about how the scripts work, to tests, to discussions, to type samples, and more, all organised by topic.

Comments welcome, via the GH links indicated at the top of each page.

Chinese and Japanese have a native way of indicating emphasis for short ranges of inline text which involves placing a small mark above or below the characters being emphasised in horizontal text, and to the right/left in vertical text.

This is now supported, using CSS, in all 3 major browser engines.

See the Gap report.

See also CSS Text Decoration for how to use this feature.

All 3 major browser engines now support the ability to create custom counter styles.

This is a significant step forward in enabling fully interoperable list numbering and other counters that reflect local approaches, especially for languages with smaller speaker populations.

See the Gap report.

By default, in runs of Latin alphanumeric text the letters are rotated 90º and run down the page. However, in some instances the alphanumerics need to stand upright. For example, this is important for acronyms.

This is now supported, using CSS, in all 3 major browser engines.
