how to Sending Email in PHP with special characters using Swift Mailer

[neovantage]

hey geeks,

I have a small mail script which will cause a PHP script to send a receipt upon clicking the submit button, by an HTML mail. This mail contains special characters, namely 'å', 'ä' and 'ö'. Whatever I try, I can't get these characters to display properly everywhere. In some email clients, these characters show up just fine, whereas in others they show up as question marks or kinda boxes. I've tried sending the mail as UTF-8, as ISO-8859- but I'm seriously stumped.

How do I send a mail from PHP using any characters while guaranteeing that the mail shows up the same everywhere?

I am using Wift Mailer library in order to send email.

Here is my swift mailer script settings

require_once 'lib/swift_required.php';
$transport = Swift_MailTransport::newInstance();
		
//Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
$message = Swift_Message::newInstance()
		
->setSubject($subject)
->setTo(array($cust_email => $name))
->setFrom(array('info@mohsinrafique.com' => 'Mohsin Rafique'))
->setSender('noreply@mohsinrafique.com')
->setReturnPath('bounce@mohsinrafique.com')
->setPriority(3)
->setCharset('utf-8')
->setBody($messagebody, 'text/html');

Kindly help me out to sort out my problem.

does the HTML mail itself contain any information about the used encoding?

testing myself (Swift 4.0.3 on Linux, Thunderbird 3.0 on Mac, XHTML/UTF-8), I had no problems.

Hmm yes and no too. I mean some static information like subject which is hard coded means

$subject="Bestä tigungsmail";

and some dynamic information came from database but that information is an entity which is encoded by this function

function charset_decode_utf_8($string) {
/* Only do the slow convert if there are 8-bit characters */
/* avoid using 0xA0 (\240) in ereg ranges. RH73 does not like that */
if (! ereg("[\200-\237]", $string) and ! ereg("[\241-\377]", $string))
return $string;
// decode three byte unicode characters
$string = preg_replace("/([\340-\357])([\200-\277])([\200-\277])/e","'&#'.((ord('\\1')-224)*4096 + (ord('\\2')-128)*64 + (ord('\\3')-128)).';'",$string);
// decode two byte unicode characters
$string = preg_replace("/([\300-\337])([\200-\277])/e","'&#'.((ord('\\1')-192)*64+(ord('\\2')-128)).';'",$string);
return $string;
}

so this is whole senerio about my html mail content. so how can i fixed that the mail shows up the same everywhere?

[Dormilich]

what I mean is, does your HTML contains a line as this?

<meta http-equiv="content-type" content="text/html;charset=utf-8">

[neovantage]

Yes but even then it is not working:(

[Dormilich]

as some mail clients display the data correctly, it seems that the others don’t support HTML email (good enough) or the encoding. what about a multipart message (html + text)?

[neovantage]

Yes i am doing this too. here it go.....!

->setBody($messagebody, 'text/html');

[Dormilich]

that’s not multipart, that’s the mime type of the message body.

[neovantage]

Then:(
Will you ellaborate it more
