Why?  Java is officially Unicode, but I haven't seen any real support
in the JDK or docs (but I haven't looked in about 3 months ;-)

My feeling back then was that basically there was a lot of work to be
done on Java i18n, in particular making translator objects.

RFC-wise, you should (or do something else about 8-bit munging
relays), but in practice this should not faze the mail transport
system (sendmail).

Are you sure the MTA (sendmail) is getting confused, and not the
receiving MUA?  Ie, do you have something as smart as Mule to look at
the alleged mojibake and see that it really is munged?

My code fragment to follow.  It works with ASCII.

        try { 
          // open a network socket on the SMTP port
          Socket server = new Socket("mail.twics.com", 25);     

          // set up network print stream
          PrintWriter sendmailout =
            new PrintWriter(
                            new BufferedWriter(
                                             new OutputStreamWriter(server.getOutputStream())), true);

         // send mail greetings and message
          sendmailout.println("HELO my-machine.twics.com\n" 
                               + "MAIL FROM:<whoever@example.com>\n"
                               + "RCPT TO:<person@example.com>\n"
                               + "DATA\n");

          // send the body of the e-mail here
          sendmailout.println("Hi, this is an automated message"
                              + " with the results of the "
                              + "form." );
          
          Date date_written = new Date();
          sendmailout.println("This note was sent on " + date_written);

    // the mail program requires a single dot on a line
          // by itself
          sendmailout.println(".");
          sendmailout.println("QUIT");
          sendmailout.close();
