Dealing with Unicode

[F]

Dear all,

I am writing an application where I need to receive text in a
different character set than the normal ascii.
I am supposed to receive string in hebrew and make some computation on
that based on the unicode values of each character.

I was trying some basic code to see how it works but I can't get the
output that I expect. For example:

System.out.println("character value:"+ (int)args[0].charAt(0));

The value in args[0] is a hebrew letter, which should have the Unicode
value between 05D0 and 05FF. However, any value that I give as an
input always returns 63 (the code for the '?').

Can anyone help me?

Kind regards,
F.

Try output to a file instead of standard out. Your console may not be
able to display certain characters, whereas you can always use a
hex-editor to analyze the contents of a file.

What is happening is that the terminal is probably not recognizing the
Hebrew letter when it is inputted. One way to test is to run from
another Java class:

Runtime.getRuntime().exec("java someClass \u05d0");

If that works, it's your terminal that is having the problem.
