| * @bug 8159420 |
| * @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. |
| * @compile -encoding utf-8 Bug8159420.java |
| * @run main Bug8159420 |
