What's the best way to handle UNC using HTML hyperlinks?

My scene: I have a asp:fileupload control that users can upload supporting documentation with during a form. It gets uploaded with a proper UNC path such as \\fileserver\shared drive\department shared\development\this-is-the-filename.pdf. It gets displayed later using that very same path within an html hyperlink, so it should theoretically open up from the browser.

The problem: is that there's sometimes spaces in the file name (I've set up a regex replace for that part though) and spaces in the folder structure in the UNC path. That's a lot harder to change. Actually, I can't change that at all.

The question: What would be the best way to handle the path? Right now every space gets replaced with a %20 which makes the path invalid and thus no file is displayed.

Thanks!
