Force same character encoding in UNIX as in Windows

Question

My program reads a simple text file and outputs the same on the console. The file contains special characters like àéèéàöäül etc. The goal of this exercise is to make java recognize special characters both on the UNIX and on the Windows system in the same manner.
I wrote the program on a Windows machine and then transferred the class file to the UNIX system and ran it there. It is giving two different outputs for the different systems.
Here is the code
public class LocaleFile {
public static void main(String [] args ) throws IOException{
System.out.println("Deafult Locale :: "+Locale.getDefault());
System.out.println("Deafult Characterset :: "+Charset.defaultCharset());
System.out.println("Resetting defailt local to de_DE ... ");
Locale newLocale=new Locale(Locale.GERMAN.toString(), Locale.GERMANY.toString());
Locale.setDefault(newLocale);
System.out.println("After resetting Locale :: "+Locale.getDefault());
BufferedReader bufferedReader=new BufferedReader( new InputStreamReader( new FileInputStream("helloworld.txt"), "ISO-8859-15"));
String line=bufferedReader.readLine();
do{
System.out.println(line);
line=bufferedReader.readLine();
while(line!=null);
bufferedReader.close();
Windows Output
Deafult Locale :: de_CH
Deafult Characterset :: ISO-8859-1
Resetting defailt local to de_DE ...
After resetting Locale :: de_DE_DE
Character set 1: Arijit
Character set 2: è!éà£
Character set 3: ü?öä$
Character set 4: []{}
End of Test
UNIX Output
bash-3.00$ java LocaleFile
Deafult Locale :: en
Deafult Characterset :: US-ASCII
Resetting defailt local to de_DE ...
After resetting Locale :: de_DE_DE
Character set 1: Arijit
Character set 2: ?!???
Character set 3: ????$
Character set 4: []{}
End of Test
bash-3.00$
*Structure of helloworld.txt*
Character set 1: Arijit
Character set 2: è!éà£
Character set 3: ü?öä$
Character set 4: []{}
End of Test
Hope to hear from you soon guys.
Thanks

Just a thought, but I'd say that it is the character encoding of the command/bash prompt that is misleading you here. It probably actually has nothing to do with the code or the data, just the way the OS is displaying it.

Well, thank you. That did raise a doubt. I changed the program slightly to write to a file say "recorded.txt" instead of printing it to the console.
Code
BufferedReader bufferedReader=new BufferedReader( new InputStreamReader( new FileInputStream("helloworld.txt"), "ISO-8859-15"));
BufferedWriter bufferedWriter=new BufferedWriter( new OutputStreamWriter(new FileOutputStream("recorded.txt")));
String line=bufferedReader.readLine();
do{
bufferedWriter.write(line.toString());
System.out.println(line);
line=bufferedReader.readLine();
while(line!=null);
bufferedReader.close();
bufferedWriter.close();
However the output remained the same
