I have a client that is receiving email incorrectly encoded. I am using the System.Net.Mail class and setting the body encoding to UTF-8. I have done a bit of reading and since I have to set the body of the email as a string encoding the data to a UTF-8 byte array really does nothing for me since I have to convert is back to a string that is UTF-16. Correct?

when I send: Il s'agit d'un message de test pour déterminer comment le système va gérer les messages envoyés à l'aide des caractères français. Merci et bonne journée.

They see: *Il s'agit d'un message de test pour déterminer comment le système va gérer les messages envoyés à l'aide des caractères français.

Merci et bonne journée.*

I have tried different encodings on the email, but I am really suspecting that the client is incorrectly decoding the email since my email client displays this correctly. Am I missing something? Is there something else that can be done?

code below

SmtpMailService.SendMail(string.Empty, toAddress, "emailaddress@emai.com", "", subject, sb.ToString(), false);

 public static bool SendMail(string fromAddress, string toAddress, string ccAddress, string bccAddress, string subject, string body, bool isHtmlBody)

        if (String.IsNullOrEmpty(toAddress)) return false;
        var toMailAddress = new MailAddress(toAddress);

        var fromMailAddress = new MailAddress(String.IsNullOrEmpty(fromAddress) ? DefaultFromAddress : fromAddress);

        var mailMessage = new MailMessage(fromMailAddress, toMailAddress);

        if (!String.IsNullOrEmpty(ccAddress))
            mailMessage.CC.Add(new MailAddress(ccAddress));

        if (!String.IsNullOrEmpty(bccAddress))
            mailMessage.Bcc.Add(new MailAddress(bccAddress));

        if (!string.IsNullOrEmpty(fromAddress)) mailMessage.Headers.Add("Reply-To", fromAddress);

        mailMessage.Subject = subject;
        mailMessage.IsBodyHtml = isHtmlBody;
        mailMessage.Body = body;
        mailMessage.BodyEncoding = System.Text.Encoding.UTF8;

        var enableSslCfg = ConfigurationManager.AppSettings["Email.Ssl"];
        var enableSsl = string.IsNullOrEmpty(enableSslCfg) || bool.Parse(enableSslCfg);
        var client = new SmtpClient {EnableSsl = enableSsl};


        return true;

What finally solved my problem was setting the contenttype on the alternate view. Just setting the msg.BodyEncoding didn't work in (among others) Outlook although Gmail displayed the email correctly.

    var msg = new MailMessage()
    msg.BodyEncoding = Encoding.GetEncoding(1252);
    msg.IsBodyHtml = true;
    //htmlBody is a string containing the entire body text
    var htmlView = AlternateView.CreateAlternateViewFromString(htmlBody, new ContentType("text/html"));
    //This does the trick
    htmlView.ContentType.CharSet = Encoding.UTF8.WebName;

Unicode and email, Although not strictly required, UTF-8 is usually also transfer encoded to avoid problems across seven-bit mail servers. MIME transfer encoding of UTF-8 makes it� Specifying the use of UTF-8 in the body of an e-mail is very similar to doing it for a HTTP response. You can specify the content-type in an e-mail header like this: 1 Content-Type: text/plain; charset=utf-8 But there is catch. The subject line of an e-mail is a header by itself, and headers must contain only ASCII characters.

Your example clearly shows that the text you send has UTF-8 encoding, which is interpreted as Windows-1252 or ISO-8859-1 encoding (see the results of several encoding errors, especially the last row in the table here).

So your code seems to be alright, the problem might be that client side just ignores the encoding of the mail body (for example because they embed it into an HTML page and the wrapper HTML uses the default ISO-8859-1 encoding).

Try to send the mail to another provider (eg. Gmail) and check the results. Well configured providers should handle the body encoding.

Solution 1

If the assumptions above are true the error must be fixed on client side. They should either process the body encoding or if it is always UTF-8, they should simply add the following tag into HTML header:

<meta http-equiv="content-type" content="text/html; charset=UTF-8">

Solution 2

If you cannot affect the client side at any cost you might want to try to use another encoding:

mailMessage.BodyEncoding = System.Text.Encoding.GetEncoding("ISO-8859-1");

Please note that your French example will be correct this way; however, non-Western European languages will not be displayed correctly.

Set up 'email encoding', Encoding UTF-8 supports almost all possible characters, including international characters. UTF-8 can represent any character in the Unicode standard. It is backwards compatible with ASCII. Users who need to send email with non-Latin data (For example, the Euro symbol, Hebrew, Chinese, Japanese, Russian, etc.) The solution I found is to manually set character encoding to UTF-8 in each email. To build up on that solution, I would like to set character encoding to UTF-8 on all my emails, including the subject line as well.

The only way is to replace the character with suitable character as you are using character map and the html is encoding your code to different garbage character

you can modify your code like :

WebClient myClient = new WebClient();

        byte[] requestHTML;
        string currentPageUrl = HttpContext.Current.Request.Url.AbsoluteUri;
        UTF8Encoding utf8 = new UTF8Encoding();
        requestHTML = myClient.DownloadData(currentPageUrl);
        var str = utf8.GetString(requestHTML);"
        str = str.Replace("’", "'");

How to Change the Character Encoding in Outlook, As you can see, Microsoft uses Western European to encode their mails. To change it, click “More” and then choose the encoding you want, such as UTF-8. That's all there is to it—you should now be able to read the email. By default, IBM Cognos components use UTF-8 encoding in emails. This value sets the default encoding used by the delivery service in this instance for all email messages. You may have older email clients or send email from IBM Cognos to cell phones and PDAs that do not recognize UTF-8.


mailMessage.BodyEncoding = UTF8Encoding.UTF8;

instead of:

mailMessage.BodyEncoding = System.Text.Encoding.UTF8;

How can I send email with UTF-8 encoding?, You are using Content-Type: text/plain; charset=UTF-8 to tell the mail reader that such message part uses UTF-8, which is fine, but What does� Hi, I tracked the problem and it is as a side effect of a issue fix done in It's actually not an problem with the EmailAddressCreate but with the "From" field that is incorrectly double encoding the name just before the email is sent.

I had a similar problem with the accents in a mail. My solution was:

mail.BodyEncoding = System.Text.Encoding.UTF8;

Using UTF-8 characters on an e-mail subject – ncona.com , Specifying the use of UTF-8 in the body of an e-mail is very similar to To encode a header using this technique you must use this format:� UTF-8: A character in UTF8 can be from 1 to 4 bytes long. UTF-8 can represent any character in the Unicode standard. UTF-8 is backwards compatible with ASCII. UTF-8 is the preferred encoding for e-mail and web pages: UTF-16

Utf8 Email Subject Encoder, Enter a subject with any character set; this tool will automatically generate an encoded version, which can be used as a subject to your emails: Subject to encode If your contacts are having trouble viewing messages you’ve sent them, we recommend using ‘UTF-8’ (Unicode) for all outgoing mail. UTF-8 is a standard encoding that’s accepted by many email clients. Here’s how to use UTF-8 encoding: Click the gear icon in the upper right, then select Settings.

  • Am I missing something? maybe showing your code?
  • there really isn't any code to show, it is more of an abstract question but I'll add it anyways
  • Is body a UTF8 encoded string when it's passed into this method?
  • It is my understanding, and I quote "A string in C# is always UTF-16, there is no way to "convert" it."
  • @RobA: it is. Beside setting your body and subject encoding to utf-8 you can't do much. If I were you I would ask your client to change their email software.
  • you can also directly set the charset while creating a new ContentType: new ContentType("text/html; charset=UTF8");
  • The problem doesn't occur in Gmail, but it does in Outlook.
  • In Outlook open the mail and click Actions/Other Actions/Encoding. What is selected? If Western European, switch to UTF-8. If always the wrong settings are auto detected check the source under Actions/Other Actions/View Source. Here you should see the HTML or plain text body. Is charset or lang defined anywhere?
  • note: MailMessage class removes this META tag from the mail bod. So we need to use the following: mail.Headers.Add("Content-Type", "content=text/html; charset=\"UTF-8\"");
  • tried to add this on my code that was reading everything in windows-1252 and all of my body message went blank.
