locale

The locale to use for network requests, in Unix locale format.

(e.g. "en_GB", "cs", "de_DE".) Use null for the default "C" locale (typically "en_US").

Typically, this locale will be used by the server-side software to localise results, such as by translating category names, or by choosing geographically relevant search results. This will vary from service to service.

The server-side behaviour is undefined if it doesn't support a given locale.
