PHPMailer and specific characters in subject (UTF-8?) - phpmailer

Question

I'm trying to send email with PHPMailer. Everythings work except UTF-8 encoding in Subject.
I still get html code (commancé and has to be "commancé") in my mail client.
$mail = new PHPMailer(true);
$mail->CharSet = 'UTF-8';
$mail->Encoding = 'base64';
try {
//Server settings
//Recipients
$mail->setFrom('kevin#expl.com', 'Kevin de Exple');
$mail->addAddress($email, $name); // Add a recipient
// Content
$mail->isHTML(true); // Set email format to HTML
$subject = 'RE: La plantation de votre arbre a commancé';
$sub = '=?UTF-8?B?'.base64_encode($subject).'?=';
$mail->Subject = $sub;
...
Could you help me? I tried everything on the web :)
Have a good day!

Answer 1

I'm not sure why you're trying to do things the hard way! The first step is setting the CharSet property to UTF-8, which you've done. For the subject, you have this:
$subject = 'RE: La plantation de votre arbre a commancé';
$sub = '=?UTF-8?B?'.base64_encode($subject).'?=';
$mail->Subject = $sub;
There's a lot of unnecessary stuff going on in there. All you need to do is:
$mail->Subject = 'RE: La plantation de votre arbre a commancé';
PHPMailer takes care of all the encoding for you. The only thing to be careful of here is to be sure that you are actually working in UTF-8 in your editor. If you're using ISO-8859-1 or similar, it won't work – though it will look identical in your code.
As for spelling mistakes, I'm going to have to leave them up to you...

Do it this way
function correct_encoding($text) {
$current_encoding = mb_detect_encoding($text, 'auto');
$text = iconv($current_encoding, 'UTF-8', $text);
return $text;
}
$mail = new PHPMailer(true);
$mail->CharSet = 'utf-8';///<-- use lowercase
//$mail->Encoding = 'base64';//usually it is not necessary
try {
//Server settings
//Recipients
$mail->setFrom('kevin#expl.com', 'Kevin de Exple');
$mail->addAddress($email, $name); // Add a recipient
// Content
$mail->isHTML(true); // Set email format to HTML
$subject = 'RE: La plantation de votre arbre a commancé';
//$sub = '=?UTF-8?B?'.base64_encode($subject).'?=';
$mail->Subject = correct_encoding($subject);
