title: Octal literals are not allowed in strict mode
body: <p>I am using Angular 2.</p>
  
  <p>When I use this in SCSS file, it works well.</p>
  
  <pre><code>.text::after {
    content: "\00a0\00a0";
  }
  </code></pre>
  
  <p>However, when I move it in </p>
  
  <pre><code>styles: [``]
  </code></pre>
  
  <p>It shows:</p>
  
  <blockquote>
    <p>Uncaught SyntaxError: Octal literals are not allowed in strict mode.</p>
  </blockquote>
  
  <p>I know codes in <code>styles: [``]</code> needs to be CSS codes.</p>
  
  <p>And I tried </p>
  
  <pre><code>styles: [`
      .text::after {
        content: "&amp;nbsp;&amp;nbsp;";
      }
  `]
  </code></pre>
  
  <p>But then the screen shows <code>&amp;nbsp;&amp;nbsp;</code> directly. How can I write it correctly?</p>
