What are the limitations of PHP's Unicode support and how does it impact file handling operations on Windows systems?

PHP's Unicode support is limited, especially when it comes to handling file names containing non-ASCII characters on Windows systems. This limitation can lead to issues such as incorrect file paths or file not found errors when trying to access files with non-ASCII characters in their names. To address this issue, one solution is to convert file names to their ASCII equivalents before performing file handling operations. This can be achieved using functions like iconv or mb_convert_encoding to transliterate the Unicode characters to ASCII. 

// Function to convert Unicode file names to ASCII equivalents
function convertUnicodeToAscii($unicodeString) {
    return iconv('UTF-8', 'ASCII//TRANSLIT', $unicodeString);
}

// Example usage
$unicodeFileName = "文件名.txt";
$asciiFileName = convertUnicodeToAscii($unicodeFileName);

// Now use $asciiFileName for file handling operations
