Download file with ( or ) causes error "The URI you submitted has disallowed characters."

I have a system I am writing. Files uploaded are stored with UUID names and the original name of the file is stored in a field. When the user wants to download the file, the system basically downloads the file as the original name.

This works fine with one exception. When the file has a parenthesis in the name, the download fails.

Here's the controller and the view that is called when the user clicks on the file:

Code:

//Controller
public function docdownload(){
  $tidDocument = $this->_uridecode($this->uri->segment(3));
  $filename = $this->uri->segment(4);
  $mimetype = $this->uri->segment(5);
  $fileurl = "files/" . $tidDocument;
  $data['filename'] = $filename;
  $data['fileurl'] = $fileurl;
  $data['mimetype'] = $mimetype;
  $this->load->view('modules/doc_download', $data);
}

//View
<?php
$header[0] = "Content-Length: " . filesize ($fileurl);
$header[1] = "Content-type: application/octet-stream";
$header[2] = "Content-disposition: attachment; filename=$filename";
$header[3] = 'Expires: 0';
$header[4] = 'Cache-Control: must-revalidate, post-check=0, pre-check=0';

foreach($header as $line){
header($line);
}


ob_clean();
flush();
readfile($fileurl);

Before anyone asks about the download class, I did try that and had problems with that earlier in development and dropped it. I don't remember why.

Anyway, can anyone give me an idea as to what I need to do here?

OK, I got it fixed. The problem was that I was sending the file name through without URLENCODEing the file name so the parens caused the problem.

Thanks anyway!
