Create Zip with utf-8 Filenames (Unicode filenames)

Demonstrates how to create a .zip archive that stores the filenames using the utf-8 character encoding. This allows for filenames of any language to be within a single Zip.

Note: utf-8 is the multibyte encoding for Unicode. When a Zip compression product declares that it supports Unicode filenames, what it really means is that it is capable of reading/writing utf-8. WinZip added support for Unicode (utf-8) filenames starting with version 11.2.

<?php

$zip = new COM("Chilkat.Zip2");

//  Any string unlocks the component for the 1st 30-days.
$success = $zip->UnlockComponent('30-day trial.');
if ($success != true) {
    print $zip->lastErrorText() . "\n";
    exit;
}

$success = $zip->NewZip('test.zip');
if ($success != true) {
    print $zip->lastErrorText() . "\n";
    exit;
}

//  To zip using utf-8 filenames, set the OemCodePage = 65001
$zip->OemCodePage = 65001;

$recurse = true;
$zip->AppendFiles('c:/temp/NonEnglishFilenames/*',$recurse);

$success = $zip->WriteZipAndClose();
if ($success != true) {
    print $zip->lastErrorText() . "\n";
    exit;
}

print 'Zip Created!' . "\n";
?>
