Wrong character encoding in sender name

I can see the default encoding set in PHPMailer.php file is as below :

/**
* Sets the Encoding of the message. Options for this are
* "8bit", "7bit", "binary", "base64", and "quoted-printable".
* @var string
*/
public $Encoding = '8bit';

Also I can see the below function does the Encoding of Header including From Name.

public function EncodeHeader($str, $position = 'text');

So someone who can dig little more, will get the issue.

Hi!
Do you have a way or idea to resolve this problem?

thanks a lot

I have the same problem with Swedish characters, but I have it in the subject as well.

I have tried different things:

hook_mail_alter:

function mymodule_mail_alter(&$message) {
  $message['subject'] = substr(iconv_mime_encode("", $message['subject']), 2);
  $message['headers']['From'] = substr(iconv_mime_encode("", $message['headers']['From']), 2);
}

With this, the subject was fixed but I couldn't change the From at all.

Changing the CharSet in PHPMailer

I did something like $mailer->CharSet = 'utf-8'; but it didn't work.

So, finally I did what I have in the patch and that solved my problem but I don't think that this is a general solution.

If we could change the PHPMailer Charset, maybe we could create a setting for that so the user could set the CharSet that they need for their project. Any ideas on this?

I ended up using the patch at https://www.drupal.org/node/2865880 because this didn't really work, especially for the Reply-to name.

Did you find any other solution yet?

Attached is a patch that uses the Unicode::mimeHeaderEncode() instead of iconv_mime_encode(). And apply the encoding to From, ReplyTo, CC, BCC and Subject.

The Unicode::mimeHeaderEncode() seems logical, especially since PhpMail does this as well!

#7 worked fine for us. tested with subject and from.

Successfully tested patch #7 and added to patch management of two productive websites. So +1 for RTBC
