Java mail encoding non english characters

Using the code below i can send an email written in non-english and although the subject appears correctly the body appears as gibberish.

Any ideas?

Thank you

public void postMail(String recipient, String subject, String message, String from) throws MessagingException, UnsupportedEncodingException {

            //Set the host smtp address
            Properties props = new Properti开发者_StackOverflow社区es();
            props.put("mail.smtp.host", "mail.infodim.gr");

            // create some properties and get the default Session
            Session session = Session.getDefaultInstance(props, null);

            // create a message
            Message msg = new MimeMessage(session);

            // set the from and to address
            InternetAddress addressFrom = new InternetAddress(from);
            msg.setFrom(addressFrom);

            InternetAddress addressTo=new InternetAddress(recipient);
            msg.setRecipient(Message.RecipientType.TO, addressTo);

            // Setting the Subject and Content Type
            msg.setSubject(subject);

            msg.setContent(message, "text/plain");
            Transport.send(msg);

        }

Try:

msg.setContent(message, "text/plain; charset=UTF-8");

Edit Changed to text/plain.

Instead of

msg.setContent(message, "text/plain");

I would write

Multipart mp = new MimeMultipart();
MimeBodyPart mbp = new MimeBodyPart();
mbp.setContent(message, "text/plain; charset=ISO-8859-7");
mp.addBodyPart(mbp);

msg.setContent(mp);

I guessed ISO-8859-7 from your name because this charset is for Greek, but maybe you can choose it more properly. Or maybe also UTF-8 works for your case.

If nothing else helps, try changing an encoding of your source files (including .java files) to UTF8. In Eclipse it is done via Window -> Preferences -> General -> Workspace : Text file encoding I had CP1252 as a default for my text files.

I am getting my text from .properties files. Changing them to UTF8 didn't help. This is insane, but switching my .java files to UTF8 solved my issue!
