Wrong attachment file name with non-ASCII character.

843834Mar 18 2010 — edited Mar 25 2010

Hi all,
I have read an email with an attchment which has non-ASCII file name from Exchange Server 2003, when I read the attachment file name using part.getFileName(), it just return µØÖ·.txt. I have set the following system properties:
System.setProperty("mail.mime.decodefilename", "true");
System.setProperty("mail.mime.decodeparameters", "true");

Can anybody help me to resolve this problem?
