Description:
------------
Hello,
I'm working in windows (french) on a console php script with Windows-1252 charset.
I'm change default_charset seting in php.ini : 
default_charset = "Windows-1252"

My script convert a .ods file in a .sql script with using phpspreadsheet lib.

I'm use a batch file to launch my php script. This allow drag-and-drop file over .bat to launch conversion.

Problem : This not work with filename countain accentuated char. Problem is in ZipArchive::Open(). Filename must be encoded with UTF-8 charset to work. 

Before open file, phpspreadsheet verify if file exist and readable with use is_file() and is_readable(). In this function, filename must be encoded with default_charset setting.

So i have a problem : If I translate filename to UTF-8, it's not work (is_file() block) but when i left CP1252 charset, ZipArchive::Open() not work.

This is inconsistent. Can you modify ZipArchive::Open()for this function use default_charset setting for filename parameters ?
Ty


Test script:
---------------
// For just test ZipArchive :
$zip = new ZipArchive();
$res = $zip->open("Différence.ods");
if ($res!== true) {
  echo 'FAIL';
} else {
  echo 'OK';
}

Expected result:
----------------
OK
(In Windows with "Différence.ods" LibreOffice calc file AND default_charset = "Windows-1252" in php.ini)

Actual result:
--------------
FAIL
(In Windows with "Différence.ods" LibreOffice calc file AND default_charset = "Windows-1252" in php.ini)
