How to handle special characters in unix

Question

I have to implement a requirement where I construct a string separated by a special character, encrypt it and send it over to an external site. The program worked fine on my local machine (WL 9.2, JDK 5.0 on Windows). However, when moved to unix, the special character turned into ?. I searched and tried quite a lot of things but didnt find a solution. Has anybody encountered and resolved this issue?
public class MyTest {
          public static void main(String[] args) {
          try {
               String string1 = "abc";
               String string2 = "def";
               String string3 = "xyz";
               String string4 = "127.0.0.1";
               String sep = "?";
String sMessage = string1 + "\u00A6" + string2+ "\u00A6" + string3+ "\u00A6" + string4+ "\u00A6" + sUserID;
               String sMessage = string1 + "\u00A6" + string2+ "\u00A6" + string3+ "\u00A6" + string4+ "\u00A6" + sUserID;
               System.out.println("Message = " + sMessage);
               BlowfishMachine encryptor = new BlowfishMachine();
               String sMessageTx = encryptor.encryptMessage(sMessage);
               System.out.println("Encrypted Message = " + sMessageTx);
               BlowfishMachine decryptor = new BlowfishMachine();
               String[] splitStr = sMessageTx.split(";");
               String sMessageRx = encryptor.decryptMessage(splitStr[0], splitStr[1]);
               System.out.println("Decrypted Message = " + sMessageRx);
          } catch(Exception ex) {
               ex.printStackTrace();
          private static String getCurrentDate() {
               try {
                    SimpleDateFormat sdf = new SimpleDateFormat("dd/M/yyyy hh:mm:ss aa");
                    return sdf.format(new Date()).toString();
               } catch (Exception e) {
                    System.out.println("Convergys  :Problem getting System Date");
                    e.printStackTrace();
               return "abc";          
}

               String string3 = "xyz";
               String string4 = "127.0.0.1";
               String sMessage = string1 + "?" + string2+ "?" + string3+ "?" + string4;
               System.out.println("Message = " + sMessage);
               String sMessage1 = string1 + "\u00A6" + string2+ "\u00A6" + string3+ "\u00A6" + string4;
               System.out.println("Message = " + sMessage1);
          } catch(Exception ex) {
               ex.printStackTrace();
}This is the output I get on Windows:
Message = abc?def?xyz?127.0.0.1
Message = abc?def?xyz?127.0.0.1
This is what I get on Unix:
Message = abc?def?xyz?127.0.0.1
Message = abc?def?xyz?127.0.0.1
