PHP unlink file with special chars in filename

Question

I can not delete file with special chars using unlink().
My file name contains for example '," and nothing happen when I using unlink().
I tried to use addslashes and iconv, but it doesn't help..
Can anybody help me?
Filename for example: aaaż'.pdf

@Solution

$newFilename = str_replace('\\','',$filename);
$newFilename = iconv("UTF-8","Windows-1250",$newFilename);
unlink($newFilename);

Answer 1

$filename = 'my\,file\,name';
unlink($filename);

Try adding antislashes, it should work.

addslashes() function doesn't add antislashes to ",".

Use str_replace() to do that:

 $filename = str_replace(',', '\,', $filename);  

Answer 2

Can't reproduce that. Check the following example:

$filename = ",;\\'\"{}$!^#\n\t.txt";
touch($filename);
unlink($filename);

It works as expected.
