[GoogleCodeExporter]

steps will reproduce garbled Chinese characters is：
  setLookAndFeel in java Swing application，like this：
   UIManager.setLookAndFeel("com.seaglasslookandfeel.SeaGlassLookAndFeel");
   UIManager.getLookAndFeelDefaults().put("defaultFont", new Font("Microsoft Yahei",Font.PLAIN,13));


the expected output is a seaglass style application in Chinese，
But， What I see instead is that some Chinese correc and others still 
garbled。


I used
product in https://code.google.com/p/seaglass/，
jre1.6 
win7 OS


All the Chinese character  in my application are used by ResourceBundle， but 
some garbled  and some correct，I want to know why and how to resolve this 
problem。
