30 * This class creates Java source files using Unicode characters
31 * that test the limits of what's possible
32 * - in situations where the platform encoding imposes limits
33 * (command line arguments, non-Unicode file system)
34 * - in situations where full Unicode is supported
35 * (file system access in UTF-8 locales and on Windows 2000++,
36 * jar file contents)
