RTFEditorKit读中文rtf文件失败

[bingbingsxy]

我用如下的代码读取中文的rtf文件,显示的全部是乱码,请问是程序哪里有错,谢谢了
RTFEditorKit kit = new RTFEditorKit();
Document doc = kit.createDefaultDocument();
FileInputStream fis = new FileInputStream(new File("C:/test.rtf"));
kit.read(fis, doc, 0);
result = doc.getText(0, doc.getLength());

System.out.println(result);
