getLocaleKey

Returns the current Options setting for localeKey.

The localeKey is in the form of a lowercase, two-letter ISO-639 language code (ll) and optionally, the uppercase, two-letter ISO-3166 country code (CC), if the locale is country-specific.

If the country code is included, it is separated from the language code with an underscore, in the form “ll_CC” (for example, “es_MX” for Mexican Spanish).
