Java strings are in Unicode - is the console capable of displaying Unicode? I'm pretty certain that Windows Explorer uses some other character encoding internally, so it doesn't mean much that it can display those characters.
[Ulf]: Java strings are in Unicode - is the console capable of displaying Unicode?
Internally a String is stored in Unicode. However when it's written to a console, it's generally converted to the platform's default encoding. For some encodings it's impossible to represent some characters, e.g. it's impossible to represent most all Asian characters in ISO-8859-1. However for a machine configured for a Chinese locale, it's quite possible that Chinese characters are supported by the default encoding - and that appears to be the case here.
[Keith]: Of Cause, DOS able to display
Did you mean "of course"? It's not at all obvious to those of us in Western countries - our environments are usually not set up to be able to display such characters.
[Keith]: I have tried getBytes(Charset charset) in difference charset of UT-8, UTC-16 and Big5.
I'm not familiar with UT-8 or UTC-16. I don't think your computer is either. Have you tried UTF-8 or UTF-16? Also, have you tried using getBytes() with no arguments? This should use your system's default encoding. Still, I think that's what your original program shown above should do too, so I don't know why it doesn't work if your console is indeed able to display these characters.
You might try looking at all your environment variables and system properties. One of these may be the name of the encoding you need to use here. I don't have a windows box available right now to look to see what environment variables are used there. And in any event my Windows system wouldn't be able to display chinese characters in the command prompt. (My Mac can, sure - but that's no use to you.) You'll have to look at the environment variables yourself to see if you can find one that looks significant. Good luck...
