Rules for Translating Applications Built in Application Builder

Use the following rules to determine which translated version to use:

Look for an exact match between the user language preference and the language code of the translated application.
Look for a truncated match. That is, see if the language and locale exist. For example, if the user language preference is en-us and the translated version of en-us does not exist, look for a translated application that has the language code en.
Use the primary application language.

For example, suppose you create an application with the primary language of German, de, and you create a translated version of the application with a language code of en-us. Users accessing this application with a browser language of en-us execute the English en-us version of the application. Users accessing the application with a browser language of en-gb view the application in the application's primary language. In this example, these users see the application in German, which is the application's primary language. For this example, you should create the translated English version using language code en to encompass all variations of en.
