Encoding Problems in JRE

Hello forum, I Have a strange problem regarding Character Encoding while running in JRE, I need to save in a text file some text and I have some special characters in it for control reasons, for ex. the char ( ◙ ).

My problem is that while this works when I run my program through the NetBeans, when I try to run the Jar file with JRE the Special characters become the (TM) char.
Why do you think that happens ?

Thanks in advance.

I might be totally wrong, but have you tried specifically selecting the character encoding for output? I had this problem when I passed some commandline args[] to program and they turned out odd. I solved the problem using PrintStream. Like so:

System.out.println("C:\\DO.EXE " + args[0]);
--> prints out badly, C:\DO.EXE "Ei mõõritelty"

message = "C:\\DO.EXE" + args[0];
PrintStream ps = new PrintStream(System.out, true, "Cp852");
ps.println(message);
--> prints out correctly, C:\DO.EXE "Ei määritelty"

Sun Java Supported Character Encodings

You might be right, I don't set a character encoding and maybe there are different defaults in sdk and in JRE,

Code:

---

final Transformer t = TransformerFactory.newInstance().newTransformer();
OutputStream outputStream = new FileOutputStream(XmlFilePath);           
t.transform(new DOMSource(document), new StreamResult(outputStream));

---

this is the code that saves the file, can anyone tell me how to set the character Encoding ?

Solved,
My problem was that before the code above, I converted byte to string without setting charset encoding.

return new String(buffer);

instead of

return new String(buffer,"UTF-8");
