Custom mail listener, set UTF-8 encoding in email header for attachment name


how to set UTF-8 encoding for the name of attachments in email header? Have Croatian letters in the name of the file. For example a text file called: "att_ććććć.txt" . After the email was send to specific email address the name of the file gets wrong formatted: "att_???". I tried:

new String(attachment.getFilename().getBytes("CP1250"), "UTF-8")




MimeBodyPart.setHeader("Content-Type", "text/html")
MimeBodyPart.setHeader("Content-Transfer-Encoding", "quoted-printable")


And still won't display the name of the file correctly. Can anyone help?

Best Regards,

Hi Sasha, sorry for the late response. You can check the solution on Look at "MimeUtility.encodeText" part. Regards, Ivan
