How can PHP scripts handle file naming conventions with special characters like Ü, Ä, Ö, and ß to ensure compatibility across different systems?

Special characters like Ü, Ä, Ö, and ß can cause compatibility issues when handling file naming conventions in PHP scripts, especially when moving files between different systems with varying encoding settings. To ensure compatibility, it's recommended to normalize the file names using PHP's `iconv` function to convert them to a standardized encoding like UTF-8. 

$filename = "Überprüfung.txt";
$normalized_filename = iconv('UTF-8', 'ASCII//TRANSLIT', $filename);
echo $normalized_filename; // Output: Uberprufung.txt
