The ‘i18n checker’ is a free service by the W3C that provides information about internationalization-related aspects of your HTML page, and advice on how to improve your use of markup, where needed, to support the multilingual Web.
This latest release uses a new user interface and redesigned source code. It also adds a number of new tests, a file upload facility, and support for HTML5.
This is still a ‘pre-final’ release and development continues. There are already plans to add further tests and features, to translate the user interface, to add support for XHTML5 and polyglot documents, to integrate with the W3C Unicorn checker, and to add various other features. At this stage we are particularly interested in receiving user feedback.
Try the checker and let us know if you find any bugs or have any suggestions.
