Description:
------------
I have a valid Zip file created with Windows 8 and with iZarc containing filenames like 12-päivä.pdf, 13-päivä.pdf
ZipArchive reads filenames wrong.
At least getNameIndex and extractTo are affected.
Test script:
---------------
<?php
mb_internal_encoding('UTF-8');
ini_set('default_charset', 'UTF-8');
$Zip = new ZipArchive();
$open = $Zip->open('test.zip');
$length = $Zip->numFiles;
for($i = 0; $i < $length; $i++)
{
$importName = $Zip->getNameIndex($i);
print $brokenImportName;
die();
// this is a specific workaround. Some characters are stuck in ASCII apparently
//$fixedImportName = str_replace(chr(132),'ä',$brokenImportName);
//print $fixedImportName;
}
?>
Expected result:
----------------
12-päivä.pdf
Actual result:
--------------
12-p�iv�.pdf

If zip file contains following files: test3/12-päivä.pdf test3/ä中华人民共和国.PDF test3/Российская Федерация.PDF test3/中华人民共和国.PDF ZipArchive will read them as: test3/12-p�iv�.pdf test3/ä中华人民共和国.PDF test3/Российская Федерация.PDF test3/中华人民共和国.PDF Broken file names can be changed to correct UTF-8 characters with: <?php // correct UTF-8 should hold together through this if($filename === mb_convert_encoding(mb_convert_encoding($filename, "UTF-32", "UTF-8"), "UTF-8", "UTF-32")) { $fixedFilename = $filename; }else { // otherwise we should use $fixedFilename = mb_convert_encoding($filename, 'UTF-8','CP850'); } ?> .ZIP File Format Specification Version: 6.3.3 APPENDIX D - Language Encoding (EFS) might hold the answers about reading file name encoding correctly from the zip file. http://www.pkware.com/documents/casestudies/APPNOTE.TXT Codepage if not UTF-8 should be CP437 if I understood correctly from the specs, although that encoding is not supported in PHP. I got good results with CP850 but I cannot verify this with workaround with every character in CP850 and CP437.
