Joomla UTF-8 encoding fails on opening the mail

Question

I have a strange issue with encoding, described as follows:

the ù is now shown as ù in the email subject. The email is sent through php mail function.

When viewing the e-mail in the mailbox, it is shown correctly. However, when anybody opens the e-mail, the ù is suddenly changed to ù.

Uw contact met Meeùs

should be

Uw contact met Meeùs

i have already used the encoding.

$emailsubject contains the above mentioned email subject.

$subject=$emailsubject;
$subject=$emailsubject;
$email_message=new email_message_class;
$email_message->SetEncodedEmailHeader("To",$to_address,$to_name);
$email_message->SetEncodedEmailHeader("From",$from_address,$from_name);
$email_message->SetEncodedEmailHeader("Reply-To",$reply_address,$reply_name);
$email_message->SetHeader("Sender",$from_address);
$email_message->SetEncodedHeader("Subject",$subject,"UTF-8");

In localhost it is working properly, but in the webserver it is not working properly. In webserver also encoding is set to utf-8 by default.

What i am doing wrong? Thanks in advance.

Answer 1

Your code is correct absolutely there is no error in it but its other things failing encoding. As I need message source headers and message to tell you exactly what is happening? I have further no information about are you sending the email as plain text or HTML. But there are generally two issue which are:

Missing Mime-Version

Reason for showing the character wrongly is developers forget to describe the message as MIME Version. if the message is missing the "Mime-Version" header that Internet mail standards require, Webmail will ignore the "charset" header completely, garbling the message unless it's already in the UTF-8 character set.

Showing Subject with Special Characters

As you want to show the subject with utf-8 encoding then you must encode the subject as:

//Setting the Language as Japan
mb_language("ja");

//Converting the string into Japan Encoding
$subject = mb_convert_encoding($subject, "ISO-2022-JP","AUTO");

//Now convert the string to MIME Header type
$subject = mb_encode_mimeheader($subject);

If the above mentioned things doesn't resolve the problem then request you post the RAW Headers of the Email as it will help in better way to resolve issue.

Answer 2

Are you test to change the charset with .htaccess ?

AddDefaultCharset   UTF-8
