getBytes() will use the default encoding
[System.getProperty("file.encoding");]
if the default encoding is not UTF-8 in your example, you are trying to
construct a utf-8 string from a non utf-8 byte array.
Try this:
utfStr=new String("滕训华".getBytes("UTF-8"),"UTF-8");
Using chinese characters directly in you java code may be seen as bad
practice. You could instead store them in a property file or similar.
Alternatively you could use the unicode representation in your java code
"\u..."
Cheers,
Lance.
