Description:
------------
ExtractTo cuts off non latin file names, no matter of codepage, til first space, so 'имя файла.txt' becomes ' файла.txt'. Filenames with no spaces gets cut off at all to extension only - '.txt'. getNameIndex returns full file names.


Also ZipArchive relies on default_charset. When default_charset is different from archive charset, files will be unpacked with broken names.


Problem appears on Ubuntu 12.04 with PHP 7.1.4 and with Debian 9 with PHP 7.0.16. First problem does not appear on Windows.

I've found that basename() does exactly the same, so it's seem to be related.

I cannot reproduce the codepage-independency of this bug. Using Debian Bullseye (PHP 7.4.33):

$ unzip -l zip.zip 
Archive:  zip.zip
  Length      Date    Time    Name
---------  ---------- -----   ----
        0  2023-04-05 10:25   áéíuó.txt
        0  2023-04-05 10:34   тест тест.txt
---------                     -------
        0                     2 files
$ cat zip.php 
<?php
$zip = new ZipArchive;
$zip->open('zip.zip');
$zip->extractTo('output/');


An ASCII locale is indeed broken:

$ LANG=C php zip.php
$ ls output/
 uó.txt  ' тест.txt'


However, a UTF-8 locale works as expected:

$ LANG=en_US.UTF-8 php zip.php
$ ls output/
 áéíuó.txt  'тест тест.txt'
