title: C# string being truncated in Firefox
body: <p>I have an ASPX app that saves some HTML into to a PDF.</p>
  
  <p>My issue is when building the filename string.</p>
  
  <p>Here is my code.</p>
  
  <pre><code>        string ext = ".pdf";
          string custname = custnamehidden.Value.ToString();
          var invnumber = invnumberhidden.Value.ToString();
  
              doc.Save(Response, false, "INV-" + invnumber + custname + ext);
  </code></pre>
  
  <p>If I run the code in EDGE, the filename looks like "INV-15452Test School.pdf", which is correct</p>
  
  <p>My issue is when I try the same thing in Firefox, the string stops at the first space "INV-15452Test"</p>
  
  <p>Any help greatly apprecitaed</p>
