php processing script used to do this:

    // convert the filename to lowercase for substring comparisons
    $lowercasefilename = strtolower($file->getFilename());

    // fixing filename - 20 character max
        // process the filename to strip out any "unsafe" or "unwise" content
        // e.g. HTML tags, spaces, non alphanumeric characters
        $lowercasefilename = strip_tags($lowercasefilename);
        $newFilename = preg_replace("/[^\.a-zA-Z0-9]/", "", $lowercasefilename);

        // if characters >= 20 combine first 10 then last 10
        $newFilenameLen = strlen($newFilename);
        if ( $newFilenameLen >= 20 )
        {
            $newFilename = substr( $newFilename, 0, 10 )
                        . substr( $newFilename, -10, 10);
        }

        $filenameDelta = strlen($file->getFilename()) - strlen($newFilename);
        $newPathname = $file->getPath().'/'.$newFilename;

        // rename file to the "safe" filename
        if ($filenameDelta != 0)
        {
            rename($file->getPathname(), $newPathname);

            writeTableRow('--', 'Fixing filename', 
                "Original filename: " . $file->getFilename() . "<br>\n"
                . "Renamed filename: " . $newFilename . "<br>\n", 
                "removed $filenameDelta characters");
        }
