* This class creates Java source files using Unicode characters
* that test the limits of what's possible
* - in situations where the platform encoding imposes limits
* (command line arguments, non-Unicode file system)

* (file system access in UTF-8 locales and on Windows 2000++,
* jar file contents)
*
* This test needs to be run in othervm as the locale is reset.
