Desktop.open can not open the file with unicode letters in the path?

Question

String filename = "/home/wenkai/received/测试.txt";
try {
     File file = new File(filename);
     Desktop.getDesktop().open(file);
     } catch(IOException ex) {
          ex.printStackTrace();
          return;
     }"测试" is just Chinese word. Now, I am using Ubuntu7.10, Gnome2.20.1, system environment setting is LANG="zh_CN.UTF-8", and java version is 1.6.0.
My system will open text file using gedit application, but when I run the code above, "file:/home/wenkai/received/测试.txt：file name or URI format error." printed in console and gedit open an temp empty file.
Do I need to encode the file path? I have tried URLEncoder.encode(String, String), but it dose not work.

I understand that, of course.  But since I don't do windows, the above is all I can offer.
