garbled filename while sending attachment in Japanese

[Tushar Bolinjkar]

I am trying to send one email with attachment whose filename is in Japanese. Every character in subject, body of the mail is in Japanese and it is coming in mail very correctly. But the filename which also in Japanese is coming as garbled characters. I even tried to open this mail on windows Japanese OS box with Japanese MS outlook.

I am using JSP and Jrun as app server which are on English OS box. I even tried doing same steps on Japanese OS box, but still the result is same. Please help me.
