@cmb: you missed the point: When filenames contain !!non-us-ascii-letters!! like !!öäü!! or
!!asian chars!! etc., ZipArchive creates filenames in a way that those files are not accessible via
PHP because the encoding is wrong.
and btw !!adding!! files to an archive containing such letters in their filename fails as well. i
have to copy them to to tmp-files first :(

Using the following slightly modified script, I can't reproduce
the issue with PHP 7.0.6 (VC14 x86 Non Thread Safe (2016-Apr-29
00:38:17)) on Windows 10:
<?php
$filename = "m\xc3\xbcller";
$zip = new ZipArchive;
var_dump($zip->open($filename,
ZipArchive::CREATE|ZipArchive::OVERWRITE));
var_dump($zip->addFromString('foo', 'bar'));
var_dump($zip->close());
var_dump(file_exists($filename));
Output
bool(true)
bool(true)
bool(true)
bool(true)
What results do you get running this script?

Description:
------------
New in PHP7 on Windows: When filenames contain non-us-ascii-letters like öäü or asian chars
etc., ZipArchive creates filenames in a way that those files are not accessible via PHP because the
encoding is wrong.
testscript output PHP 5.5.35:
php default_charset: UTF-8
bool(true)
testscript output PHP 7.0.6:
php default_charset: UTF-8
bool(false)
run on Windows Server 2012 R2 and Windows7
Test script:
---------------
print "php default_charset: ".ini_get('default_charset')."\n"; // just
4 info (UTF-8)
$filename = "bugtest_müller-lüdenscheid.zip"; // just an example
$filename = utf8_encode($filename); // simulating my database delivering utf8-string
$zip = new ZipArchive();
if( $zip->open($filename, ZipArchive::CREATE | ZipArchive::OVERWRITE) === true )
{
$zip->addFile('bugtest.php', 'bugtest.php'); // copy of script file itself
$zip->close();
}
var_dump( is_file($filename) ); // delivers ?
