title: Angulkar2 file saver-save in ANSI format
body: <p>I am using Angular4 in my app and my UI downloads a file. The file content is coming as a reponse in the format Window-1252 from Java. I am using Blob to download the text file, when I downloaded the file is saved as UTF-8 even though I specified charset-ansi, how can we resolve this? below is the code for the blob.</p>
  
  <pre><code>const filename = 'test.txt';
  const blob = new Blob([response._body], { type: 'text/plain;charset=ansi' 
  });
  saveAs(blob, filename);
  </code></pre>
