Message uses a character set that is not supported by the internet service

Question

Does any one have any advice on how to fix this problem?
E-mails sent from my iphone 3G periodically arrive in an unreadable form at the recipient. The body of the e-mail has been replaced with the message "This message uses a character set that is not supported by the internet service...." The problem e-mails also include an attachment that contains an unformatted text file containing the original message surrounded by what appears to be lots of formatting data that is displayed as gibberish.
This occurs sometimes, but not always, even with the same recipients. I am sending e-mail through a G-mail account that is configured on the iphone using IMAP. I have tried the gmail account to use the two available formatting options for mail, but neither fixes the problem.
I have also upgraded to 2.01 and restored a few times without impact.

Hi,
I got somewhat similar problem with special charecters(German umlaud �,�,�..).
I create a file with java having special charecters in it. Now if I open this file I am able to view the special charecters in it.But If I attach this file send it using following code then receiver can not see the umlaud charecters in it.They get replaced by _ or ?
MimeBodyPart mbp2 = new MimeBodyPart();
FileDataSource fds = new FileDataSource(fileName);
mbp2.setDataHandler(new DataHandler(fds));
mbp2.setFileName(output.getName());
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp2);
msg.setContent(mp);
Transport.send(msg);
From you message it looks like you are able to send the mail attachment correctly(by preserving special charecters).
Can you tell me what might be wrong in my code.
I appriciate your efforts in advance.
