+     * language code. The codes from ISO 639-1 are used when available. Otherwise, codes from
+     * ISO 639-2/T are used. REGION specifies an uppercase ISO 3166-1 country/region identifier.
+     * For example, the locale name for English (United States) is "en-US" and the locale name
+     * for Divehi (Maldives) is "dv-MV".

+     * If the locale is a neutral locale (no region), the LOCALE_SNAME value follows the
