      • getISOLanguages

        public static String[] getISOLanguages()
        Returns an array of two-letter ISO 639-1 language codes, either from ICU or our cache.

      • getISOCountries

        Returns an array of two-letter ISO 3166 country codes, either from ICU or our cache.

      • localeFromIcuLocaleId

        public static Locale localeFromIcuLocaleId​(String localeId)
        Returns the appropriate Locale given a String of the form returned by toString. This is very lenient, and doesn't care what's between the underscores: this method can parse strings that Locale.toString won't produce. Used to remove duplication.
