What are some best practices for troubleshooting and resolving character encoding issues in PHP templates?

Character encoding issues in PHP templates can be resolved by ensuring that the correct encoding is specified in the HTML meta tag, setting the appropriate charset in the PHP header, and using functions like mb_convert_encoding() to handle encoding conversions.

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>Character Encoding Example</title>
</head>
<body>
<?php
header('Content-Type: text/html; charset=UTF-8');
echo mb_convert_encoding($content, 'UTF-8', 'ISO-8859-1');
?>
</body>
</html>
