How can PHP scripts be optimized to handle special characters and maintain proper encoding for web content?

Special characters can cause encoding issues in PHP scripts, leading to garbled or incorrect display of web content. To handle special characters properly, PHP scripts should use functions like htmlspecialchars() to convert special characters to HTML entities and ensure proper encoding. This helps prevent security vulnerabilities like cross-site scripting attacks and maintains the integrity of the web content. 

// Example PHP code snippet to handle special characters and maintain proper encoding
$html_content = "<p>This is a special character: &</p>";
$encoded_content = htmlspecialchars($html_content, ENT_QUOTES, 'UTF-8');
echo $encoded_content;
