Java application doesn't work with utf8 encoding in linux?

Question

I use Linux OS and local i18n resource file for Java internalization. Below is my source code. The Frame title can be internalized without any problem, but the button text can't be shown correctly. What is the problem with my code? It works fine in Windows XP.
Locale locale = new Locale("zh", "CN");
          Locale.setDefault(locale);
          ResourceBundle rb = ResourceBundle.getBundle("ui/demo/i18n/ui_demo",locale);
          System.out.println(rb.getString("OK"));
          JFrame frame = new JFrame("");
          frame.setTitle(rb.getString("OK"));
          JButton button = new JButton(rb.getString("OK"));
          frame.add(button);
          frame.setSize(100, 100);
          frame.setVisible(true);

What is the default encoding of the system, and what character encoding is used in the file?
If they are both the same, no problem, if not, then you're going to have to do some converting.
Edit: of course, I thought that Java used "?" for unknown characters. So, the "black boxes", might also, possibly, be font problems.
Both of these are only educated guesses, don't take them as Gospel (and, in all likelyhood, they are probably both at least slightly off-base).thanks for this information. But if the problem is OS encoding, why the Frame title can be shown correctly?
