How Can I Fix Garbled Characters in My UTF-8 Emails?

Troubleshooting UTF-8 Email Encoding

If you're encountering garbled characters in emails you send, you may need to adjust the encoding to support UTF-8. Let's troubleshoot the issue.

Cause:

Your email client/script may not be correctly encoding the body of the email.

Solution:

To ensure proper character encoding, add the "Content-Type" header with the appropriate charset. For UTF-8, the header should be:

Content-Type: text/html; charset=UTF-8

Implementation:

Using the Mail::Factory library:

$headers = array(
  'Content-Type' => 'text/html; charset=UTF-8'
);

$mail = $smtp->send($to, $headers, $body);

Using the native mail() function:

$headers = "Content-Type: text/html; charset=UTF-8";
mail($to, $subject, $message, $headers);

By adding the correct header, the email body will be encoded in UTF-8, ensuring that special characters display correctly in the recipient's mailbox.
