title: How to input a null character into a web form?
body: <p>I am testing an ASP.NET web form which needs to filter out null characters from input.</p>
  
  <p>To test this functionality, how can I actually type a null character in the html form? I've tried Alt+0 but it does not work.</p>
  
  <p>I know I can do it in a GET request by using "%00" in the URL. However, I want to do it in a form POST.</p>
