How can PHP developers ensure proper handling of character encoding to avoid displaying cryptic characters?

PHP developers can ensure proper handling of character encoding by setting the correct charset in both the HTML meta tag and the PHP header. This will ensure that the browser interprets the text correctly and displays it in the intended encoding. Additionally, developers can use functions like mb_convert_encoding() to convert strings to the desired encoding before outputting them. 

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
</head>
<body>
<?php
header('Content-Type: text/html; charset=UTF-8');
echo mb_convert_encoding($string, 'UTF-8');
?>
</body>
</html>
