Java EE (Java Enterprise Edition) General Discussion

I am using java mail api to send emails. It has to support for both English and Arabic Langauge. Its working fine with the body part for both the langauges Arabic and english.
But i am facing problems in Subject for Arabic langauge. Arabic Subject in emails works fine with gmail, yahoo and with some of the machines in outlook(where arabic support is installed/enabled), but in some of the machines the arabic subject displays as junk character or question marks (?????). below is the peace of code for reference.

I want that the arabic subject should work in the outlook in the machines even where arabic support is not installed. Kindly let me know where i am going wrong and advice me with the changes required to get the required out put.
