Re: php can't resolve 8.3 paths to unicode filenames, is that expected ?

Yes, but how does the function even know that there are multibyte
in it's arguments ? Since it was given the ascii compliant name ?
And why 16 bit apps don't experience any errors since they are much
older than php ? Maybe because they are ignorant about multibyte paths ?
Shouldn't php be ignorant too if it can't handle it ?

Yes, but there are no question marks in shortenened path.

But how the php function does know about that ?
Now I tried to open that greek file in old msdos 622 and it worked
without any issue. Although I know it will mess it name if I try to
change it. And I expect the same from php. But I don't want here
to rename anything in php.

So it should and it is a bug. And it is the two different things if 
I want you to make PHP Unicode complying, which I do not.
I want you to make php completely ignorant of unicode paths
as are the old 20 yo apps until it will be able to 100% successfully handle it.

under Windows, os.path.abspath returns non-ASCII bytes paths as question marks
but what you need abspath for ? and why php filesystem functions need 
to know absolute path ?


another thing I noticed is that php doesn't as I thought try to translate the path, if I give it
the one without unicode I get back it in the same shortened form
so what is happening here ? it doesn't give the user absolute path but it must
be using it somewhere internally

<?
$FS = new \COM('Scripting.FileSystemObject', null, CP_UTF8);
$FS->CreateTextFile("c:\\zzzzzzzzz_ellada.txt");
$ShortPath = $FS->GetFile("c:\\zzzzzzzzz_ellada.txt")->ShortPath;
echo "short path: ".$ShortPath."\n";
$handle = fopen($ShortPath, 'r');
echo "handle path: ".stream_get_meta_data($handle)['uri']."\n";
// echoes: C:\ZZZZZZ~2.TXT
?>
