Error with extended characters

Question

hi i have a problem with extended characters and it only happens when i have an attachment with the mail
MimeBodyPart bp = new MimeBodyPart();
String content = "� � � � � � � � � � � � �� � � � � � � � � � �  � �";
bp.setContent( content, "text/plain; charset=UTF-8" );
mp.addBodyPart( bp );
//code for adding a attachment is added to the mp using MimeBodyPart
msg.setContent( mp ); // add Multipart
msg.saveChanges(); // generate appropriate headers
ByteArrayOutputStream baos = new ByteArrayOutputStream();
msg.writeTo( baos );msg is a MimeMessage.
Now this msg is stored in a cache and later retrieved using
String s = "";
            java.lang.Object o = msg.getContent();
            if ( o instanceof String )
                s = (String) o;
            else if ( o instanceof Multipart )
                try
                    Multipart mp = (Multipart) o;
                    MimeBodyPart bp = (MimeBodyPart) mp.getBodyPart( 0 );
                    s = (String) bp.getContent();
                catch ( Exception e )
                    cLog.error(e.getMessage(),e);
            }now s contains "�€ �� �‚ �ƒ �„ �… �† �‡ �ˆ �‰ �Š �‹ �Œ �� �� �� �� �� �� �� �� �� �� �� �� ��" which is wrong.
This has been bugging me for a couple of days now.
could anyone please give a solution.
Many Thanks in advance

Using these literal non-ASCII characters in the string constant might
look great in your editor but might not be giving the correct Unicode
values. Try replacing the special characters with Unicode escapes
(\u####).
If that doesn't work, step through the original string and print out
each character as an integer. Then do the same for the string you
fetch from the message. Compare the integer values. If they're
not the same, post the details. If they are the same, the problem
is most likely in how you're displaying the characters you read
from the message.
