Reading Arabic chars from text file

I had finished a project in which I read from a text file written with notepad. The characters in my text file are in Arabic language,and the file encoding type is UTF-8. When launching my project inside Netbeans(7.0.1) everything seemed to be ok,but when I built the project as a (.jar) file the characters where displayed in this way: ÇáãæÇÞÚááÊØæíÑ. How could I solve This problem please?

Maybe this example will help a little. I will try to print content of utf-8 file to IDE console and system console that is encoded in "Cp852".

My d:\data.txt contains ąźżćąś adsfasdf

Lets check this code

//I will read chars using utf-8 encoding
BufferedReader in = new BufferedReader(new InputStreamReader(
        new FileInputStream("d:\\data.txt"), "utf-8"));

//and write to console using Cp852 encoding (works for my windows7 console)
PrintWriter out = new PrintWriter(new OutputStreamWriter(System.out,
        "Cp852"),true); // "Cp852" is coding used in
                    // my console in Win7

// ok, lets read data from file
String line;
while ((line = in.readLine()) != null) {
    // here I use IDE encoding
    System.out.println(line);
    // here I print data using Cp852 encoding
    out.println(line);
}

When I run it in Eclipse output will be 

ąźżćąś adsfasdf
Ą«ľ†Ą? adsfasdf

but output from system console will be

enter image description here

Most likely you are using JVM default character encoding somewhere. If you are 100% sure your file is encoded using UTF-8, make sure you explicitly specify UTF-8 when reading as well. For example this piece of code is broken:

new FileReader("file.txt")

because it uses JVM default character encoding - which you might not have control over and apparently Netbeans uses UTF-8 while your operating system defines something different. Note that this makes FileReader class completely useless if you want your code to be portable.

Instead use the following code snippet:

new InputStreamReader(new FileInputStream("file.txt"), "UTF-8");

You are not providing your code, but this should give you a general impression how this should be implemented.
