How Can I Fix Garbled Text in UTF-8 Encoded Emails?

Resolving UTF-8 Email Encoding Issues

Sending emails with non-English characters can sometimes result in garbled text when received. To address this issue with UTF-8 email encoding, let's explore the problem and its solution.

The Problem: Garbled Non-English Characters

When sending emails that contain characters outside the English alphabet, such as 余生ä»ä», some recipients may encounter garbled text upon receiving them. This is because the email is not properly encoded using UTF-8, the standard encoding used for most non-English languages.

The Solution: Specifying Content-Type and Charset

To prevent garbled text, it is necessary to specify the correct Content-Type and charset headers in the email. These headers indicate the encoding used for the email body.

To add these headers in Perl using Mail::Factory(), you can use the following code:

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

If using the native mail() function, the $headers array becomes the fourth parameter:

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

For PEAR Mail::factory(), the code would be:

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

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

By including these headers in the email, the recipient's email client will be able to interpret the non-English characters correctly, resolving the garbled text issue.
