How Can I Fix UTF-8 Character Display Issues When Sending Emails?

Sending UTF-8 Emails with Character Display Issues

When composing and sending emails, you may encounter situations where non-English characters do not display correctly. The email may only show incomprehensible characters, such as "余生ä»ä»."

Cause

This issue arises when the email's encoding is not properly set to handle UTF-8 characters. UTF-8 is a character encoding standard that allows for the representation of multiple languages and characters.

Solution

To resolve this issue, you can add a "Content-Type" header to the email message body, specifying the character encoding as UTF-8.

Using $headers Variable

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

Using native mail() function

mail($to, $subject, $message, $headers);

Using PEAR Mail::factory()

$smtp = Mail::factory('smtp', $params);

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

By adding the "Content-Type" header and specifying UTF-8 as the character encoding, the email will be encoded correctly, ensuring that non-English characters are displayed accurately.
