How can the ZipArchive class in PHP be utilized effectively to handle special characters like Umlauts in file names?

Special characters like Umlauts in file names can cause issues when using the ZipArchive class in PHP because it may not handle these characters properly. To effectively handle special characters like Umlauts in file names, you can encode the file names using the mb_convert_encoding function before adding them to the zip archive.

$zip = new ZipArchive();
$zipFileName = 'archive.zip';
$zip->open($zipFileName, ZipArchive::CREATE);

$fileName = 'file_with_umlauts_ä.txt';
$encodedFileName = mb_convert_encoding($fileName, 'UTF-8', 'UTF-8');
$zip->addFile($fileName, $encodedFileName);

$zip->close();
