PHPMailer character encoding issues


I try to use PHPMailer to send registration, activation. etc mail to users:

$mail -> charSet = "UTF-8";
$mail = new PHPMailer();
$mail->Host     = "";  
$mail->From     = "";
$mail->SMTPAuth = true; 
$mail->Username ="username"; 
//$mail->FromName = $header;
$mail->FromName = mb_convert_encoding($header, "UTF-8", "auto");
$mail->AddBCC('', 'firstadd');
$mail->Subject  = $sub;
$mail->Body = $message;
$mail->WordWrap = 50;  
if(!$mail->Send()) {  
   echo 'Message was not sent.';  
   echo 'Mailer error: ' . $mail->ErrorInfo;  

The $message is contain latin characters. Unfortunately all webmail (gmail,, emailaddress.domain.xx) use different coding.

How can I force to use UTF-8 coding to show my mail exactly same on all mailbox?

I try to convert the mail header width mb_convert_encoding(), but with no luck.

Accepted Answer

If you are 100% sure $message contain ISO-8859-1 you can use utf8_encode as David says. Otherwise use mb_detect_encoding and mb_convert_encoding on $message.

Also take note that

$mail -> charSet = "UTF-8"; 

Should be replaced by:

$mail->CharSet = 'UTF-8';

And placed after the instantiation of the class (after the new). The properties are case sensitive! See the PHPMailer doc fot the list & exact spelling.

Also the default encoding of PHPMailer is 8bit which can be problematic with UTF-8 data. To fix this you can do:

$mail->Encoding = 'base64';

Take note that 'quoted-printable' would probably work too in these cases (and maybe even 'binary'). For more details you can read RFC1341 - Content-Transfer-Encoding Header Field.

$mail -> CharSet = "UTF-8";
$mail = new PHPMailer();

line $mail -> CharSet = "UTF-8"; must be after $mail = new PHPMailer(); and with no spaces!

try this

$mail = new PHPMailer();
$mail->CharSet = "UTF-8";
