If you have problem using mb_send_mail to send utf-8 mails, you have to know the following things (I've spent hours on the net before finding the correct php code) :
- You have to use the mb_encode_mimeheader function on the sender name and on the recipient name (on names, not on emails !).
- Subject and message are automatically encoded.
- Add - at least - the following header :
$headers = "Mime-Version: 1.0\n";
$headers .= "Content-Type: text/plain;charset=UTF-8\n";
$headers .= "From: $sender";
- Last but not least, beware of the internal encoding, which is needed by mb_encode_mimeheader function in order to encode properly. I had to set the internal encoding to UTF-8 in order to make it work properly :
mb_internal_encoding("UTF-8");
