title: Blank space is appearing as question mark
body: <p>I just started with angular. I am taking .html file as input and previewing the content of the .html  in a web page using sanitizeHtml pipe. the problem is the blank spaces are appearing as question marks. I tried using 
  <code>&lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /&gt;</code>
  but it is not working and there is no backend intervention in this process. Thanks in advance</p>
