Extended ASCII characters

I have read that Java uses UNICODE. And when I tried to put Extended ASCII characters as command line arguments to a Java program, it didn't display them correctly. Is there any way to display Extended ASCII character set in Java?
(this question may be termed as a "hurried" question, as I have myself not experimented enough before asking you people).
thanks.

Post the code that you used to play with the unicode.

You can take the example of simply using the statement:
System.Out.println(arg[1]);
where arg[1] represents a command line agrument. If you put in an extended ASCII character here, it will not display it correctly (at least on my system).

Well, it took some poking around, but I finally found this fascinating disertation on the Lexical Structure of the Java Language.
http://java.sun.com/docs/books/jls/second_edition/html/lexical.doc.html
The sum of it is that the conversion between unicode and ascii is a compile time function, and it happens very early in the compiling heirarchy.
When you input a String at the command prompt there is no compiler around to translate it, there is only the JRE, so it will remain a String.

Thanks for the link. Will be reading it and posting if I have any further doubts on this topic.
