Official XBOX services languages that are available on console
While the default fallback is en-US, there are exceptions if the locale’s language root is either “es”, “fr”, or “sa”.
Xbox Services Language Fallback
Locale fallback table used by XBOX services when a user’s system language has no localized string, including the default en-US fallback rules.
If a user’s system language setting is not included in a title’s localized strings, XBOX services are able to automatically fallback to a language that is closest to it.
For example, if a console is set to Belgium French (fr-BE) and a localization for an achievement isn’t available for it, then the system will check for a localization in its fallback language, France French (fr-FR). If a localization still cannot be found, it will fall back further into the default en-US.
