Err... OK, sorry. You (Vinita Batra) are right. The $filename argument
to filter and filter_multipart _does_ contain garbage. It looks like
mimedefang looses the encoding, so the data becomes worthless.

It's more reliable to get your own filename out of the entity itself,
so you can preserve the encoding. Sorry, no code example, you'll have to
dig into the manpage of MIME::Entity and MIME::Tools.

mimedefang throws the character set away. At least for the $filename
argument.
