VirtualViewer HTML5 for Java localization supports auto detecting the language settings the user’s browser is configured to use. It then looks for a localization file in that language. If a localization file for the corresponding language exists, it will be used to display terms throughout the UI in that language.

For more information on setting language preferences in a browser, please see http://www.w3.org/International/questions/qa-lang-priorities.en.php.
