title: Delete files with special characters in filenames
body: <p>I need to delete old files with special characters in filenames like space,<code>,</code>,<code>(</code>,<code>)</code>,<code>!</code> and so on via PHP. Classic <code>unlink($filename)</code> does not work for these files. How can I transform filenames to filenames which accepts unlink function and filesystem? It's running on a Solaris machine and I don't have another access to it.</p>
