I'm using the php ZipArchive class in order to generate a zip archive. I use the second parameter of the addFile method in order to set the name of the file in the archive (since the real file on disk has a different name). Some of the names must contain french accents (such as é). When I download the archive, the accents aren't correctly displayed in the file name. What encoding should I use for the file names ? (the application uses UTF-8)

  • Zip's a pretty old format, and predates Unicode. Older pre-2007 versions of the format most likely just use standard extended ascii. After '07, the new spec allowed for UTF-8. Check which file version you're generating. – Marc B Feb 15 '11 at 16:20

It is php bug #53948, see official bug report.

Suggested workaround (worked for me):

$zip->addFile($file, iconv("UTF-8", "CP852", $local_name));

Use DOS encoding. My file names has cyrillic characters, so I'm encoding the file names from cp1251 (Windows) to cp866 (DOS), upon passing the filename to $zip->addFile().

  • Thanks a bunch! How have you figured exactly what encodings to use? – YakovL Jan 18 '18 at 22:26
  • I didn't figured it out, because I always knew it. :)) lol Well, actually I used RAR since 1992 or 1993. RAR was originally written for DOS and later ported to Windows as WinRAR. So DOS code tables is native for RAR. – Aleksey Kuznetsov Dec 01 '18 at 23:56

Zip files don't have a specified encoding; the archive tool must guess (or assume) the encoding used. Try CP1252 first, then go from there.

Depends on the Windows system e.g French, internal zip of Windows use IBM850 as encoding.
