Bug description:ZipArchive converts filenames to unrecoverableform

Description:
------------
I have a test zip archive with only one dir named (АБВГД) created
under Windows with Russian locale. If you will look to the zip file in
HEX mode you will see the dir name "80 81 82 83 84 2F" (АБВГД/),
five 1-byte chars + slash. Under PHP 5.4 the ZipArchive::getNameIndex
function onthis archive returned the name as is - in cp866 encoding. So
I was able to convert it to correct text. After upgrading to PHP 5.6
this function returns names transcoded to something unrecoverable. The
result of the ZipArchive::getNameIndex transcoded by PHP internally to
five *2-bytes* chars + slash! I tried to set default_encoding ini
setting, but without success. So I can not work properly with such
archives at all.

Run test script under precompiled PHP 5.4 from the php.net and the same
PHP 5.6 and you will see different results:




Test script:
---------------
<?
echo setlocale(LC_ALL, 'Russian_Russia.20866'), "\n";
ini_set('default_charset', 'cp866');

$zip = new \ZipArchive();
$res = $zip->open('test.zip');
if ($res !== true) {
	echo 'Error opening: ' . $res;
	die();
}


for ($i = 0; $i < $zip->numFiles; $i++) {
	$stat = $zip->statIndex($i);
	$fileNameInArc = $zip->getNameIndex($i);

	echo $fileNameInArc, "\n";
	echo iconv('cp866', 'utf-8', $fileNameInArc), "\n";
}


Expected result:
----------------
php.5.4.32\php test.php
Russian_Russia.20866
АБВГД/
╨Р╨С╨Т╨У╨Ф/


Actual result:
--------------
php.5.6.21\php test.php
Russian_Russia.20866
