An example of such a locale is “zh-Hant-HK”, which gets converted to a String as “zh_HK_#Hant” but read back as “zh-Hant”. LocaleTypeDescriptor.fromString builds the Locale instance using uses the Locale constructor, which does not allow specifying a script or extension; alternatives would be to use [ Locale.forLanguageTag |https://docs.oracle.com/javase/8/docs/api/java/util/Locale.html#forLanguageTag-java.lang.String-] , or [ Locale.Builder |https://docs. oracle.com/javase/8/docs/api/java/util/Locale.Builder.html].
