i have the followed code

```
  $zip = new ZipArchive;
  $res = $zip->open('tmp/articles.zip');
  if ($res === TRUE) {
    $zip->extractTo('tmp/');
    $zip->close();
  }

```

It works fine for archives with english filenames, but if i made archieve with russian characters, i have unreadable filenames. What should I do?

UPD: It doesn't work correctly when i use "unzip" from bash too.
