Follows the RFC 1766 standard in the format "[languagecode2]-[country/regioncode2]", where [languagecode2] is a lowercase two-letter code derived from ISO 639-1 and [country/regioncode2] is an uppercase two-letter code derived from ISO 3166. For example, U.S. English is "en-US". In cases where a two-letter language code is not available, the three-letter code derived from ISO 639-2 is used; for example, the three-letter code "div" is used for cultures that use the Dhivehi language.
