How to implement message body encoding when sending with mail() function?

Question

PHP

Good day!
Help with the encoding of the body of the message, EXACTLY the body of the message.
I searched, but apart from the from and subject encoding, there is nothing.
Required :
$to = '[email protected]';
$subject= 'subject';
$msg = "Message text"; // set the encoding for the content of this variable!!!
mail($to, $subject, $msg, 'From: '.$email);
Thanks in advance and sorry if this is a simple question.

/* Для отправки HTML-почты вы можете установить шапку Content-type. */
$headers= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";

/* дополнительные шапки */
$headers .= "From: Birthday Reminder <[email protected]>\r\n";
$headers .= "Cc: [email protected]\r\n";
$headers .= "Bcc: [email protected]\r\n";

/* и теперь отправим из */
mail($to, $subject, $message, $headers);
