What are some best practices for handling special characters and non-Latin scripts like Cyrillic in PHP scripts?

Special characters and non-Latin scripts like Cyrillic can pose challenges in PHP scripts, especially when handling input/output, encoding, and displaying text. To handle these characters properly, it's important to ensure that your PHP script uses the correct character encoding (such as UTF-8) and handles input/output in a consistent manner. 

// Set the character encoding to UTF-8
header('Content-Type: text/html; charset=utf-8');

// Convert input to UTF-8
$input = mb_convert_encoding($input, 'UTF-8', 'auto');

// Output text in UTF-8
echo mb_convert_encoding($output, 'UTF-8', 'auto');
