What are the considerations for handling special characters, such as umlauts, in file names within PHP scripts and functions like fopen()?

Special characters, such as umlauts, in file names can cause issues when handling files in PHP scripts, especially when using functions like fopen(). To properly handle these characters, it is recommended to use UTF-8 encoding and functions like utf8_encode() or utf8_decode() to ensure the correct representation of special characters in file names. 

// Example of handling special characters in file names using UTF-8 encoding
$file_name = "file_with_ümlaut.txt";
$encoded_file_name = utf8_encode($file_name);

$file_handle = fopen($encoded_file_name, "r");

// Perform file operations

fclose($file_handle);
