W3C Internationalization Checker (Prototype only!)
Is your Web site internationalized?
This checker performs various tests on a Web Page to determine its level of internationalisation-friendliness. It also summarises key internationalization information about a page, such as character encoding and language declarations, etc. Please refer to the About page for more details.
If you wish to validate specific content such as markup validation, mobileOK, RSS/Atom feeds, CSS stylesheets, or to find broken links, there are other validators and tools available.
The checker is still only a prototype, so there are guarranteed to be bugs and missing features. It will be developed over the coming months, but it has been made available for use now since it is likely to be helpful to many people already. If you have suggestions for ways to improve the checker, please fill in the feedback form.
