Please note that ZIP archives do not support unicode encodings like UTF-8, so multi-byte characters cannot be shown in standard ZIP viewers like WinRAR or 7-zip. However, the text will stored as-is, so it is at least possible to display UTF-8 comments in your own desktop or web applications. If you want to test with PHP and output in a browser, don't forget to set page charset to UTF-8 too:
header("Content-Type: text/plain; charset=utf-8");

Zip archives are encoded in ISO-8859-1 when stored but comments seem to be added in UTF-8 everytime. So...
<?php
$zip->setArchiveComment("Peña"); //outputs "Peña" as the comment.
$zip->setArchiveComment("Peña"); //outputs "NULL" as the comment / no comment is displayed.
?>
Using mb_internal_encoding() or mb_http_output() wont change this behavior.
At the end you can fix your corrupted comment using something like str_replace();
Consider this:
<?php
$zip = new ZipArchive;
$res = $zip->open('test.zip', ZipArchive::CREATE);
if ($res === TRUE) {
$zip->addFromString('test.txt', 'file content goes here');
$zip->setArchiveComment('Peña'); //outputs "Peña" as the comment.
$zip->close();
$file = file_get_contents('test.zip');
file_put_contents('test.zip', str_replace("Peña", utf8_decode("Peña"), $file)); //outputs "Peña" as the comment. FIXED!
echo 'ok';
} else {
echo 'failed';
}
?>
