title: Angular 5 file-saver saveAs CSV file encoding to ANSI
body: <p>I use Angular 5 + <code>"file-saver": "^1.3.3"</code> + <code>"@types/file-saver": "^1.3.0"</code></p>
  
  <pre><code>import { saveAs } from 'file-saver';
  const filename = parts[1].split('=')[1];
  const blob = new Blob(['\ufeff', response.body], { type: 'text/csv' });
  saveAs(blob, filename);
  </code></pre>
  
  <p>create <strong>UTF-8</strong> file</p>
  
  <pre><code>import { saveAs } from 'file-saver';
  const filename = parts[1].split('=')[1];
  const blob = new Blob([response.body], { type: 'text/csv' });
  saveAs(blob, filename);
  </code></pre>
  
  <p>create <strong>UTF-8 w/o BOM</strong> file</p>
  
  <p>But I need create <strong>ANSI</strong> file (for Excel and an other client)</p>
  
  <p>I try <code>{ type: 'text/csv;charset=ansi;' }</code> but do not work.</p>
