Passing command line unicode argument to Java code

Question

I have to pass command line argument which is Japanese to Java main method. If I type Unicode characters on command-line window, it displays '?????' which is OK, but the value passed to java program is also '?????'. How do I get the correct value of argument passed by the command window? Below is sample program which writes to a file the value supplied by command line argument.
public static void main(String[] args) {
String input = args[0];
try {
String filePath = "C:/Temp/abc.txt";
File file = new File(filePath);
OutputStream out = new FileOutputStream(file);
byte buf[] = new byte[1024];
int len;
InputStream is = new ByteArrayInputStream(input.getBytes());
while ((len = is.read(buf)) > 0) {
out.write(buf, 0, len);
out.close();
is.close();
} catch (Exception e) {
e.printStackTrace();
}

Answer 1

To clarify a little:
If the "command line" means a console opened from the operating system, then the problem is that your machine's operating system can't handle the Unicode characters you want (at least, not in the console mode). If you can't configure the machine to accept Unicode on the command line, you'll have to investigate some other means of passing the argument to your app, as the other poster mentioned.
