+ * @summary Checks the proper execution of LanguageRange.parse() and
+ * other LocaleMatcher methods when used in the locales like
+ * Turkish, because the toLowerCase() method is invoked in the
+ * parse() and other LocaleMatcher methods.
+ * e.g. "HI-Deva".toLowerCase() in the Turkish locale returns
+ * "hı-deva", where 'ı' is the LATIN SMALL LETTER DOTLESS I character
+ * which is not allowed in the language ranges/tags.
