By default, the Maps JavaScript API uses the user's preferred language setting as specified in the browser, when displaying textual information such as the names for controls, copyright notices, driving directions and labels on maps. In most cases, it's preferable to respect the browser setting.
When you load the Maps JavaScript API from maps.googleapis.com it applies a default bias for application behavior towards the United States. If you want to alter your application to serve different map tiles or bias the application (such as biasing geocoding results towards the region), you can override this default behavior by adding a region parameter to the Githubissues.
Githubissues is a development platform for aggregating issues.
