title: Identical strings not matching in Jest
body: <p>The following test fails:</p>
  
  <pre><code>test('', () =&gt; {
    const result = new Intl.NumberFormat('sv-SE', {
      style: 'currency',
      currency: 'SEK',
      minimumFractionDigits: 0,
      maximumFractionDigits: 0,
    }).format(1000)
  
    expect(result).toEqual('1 000 kr')
  })
  </code></pre>
  
  <p>It returns the following hint:</p>
  
  <pre><code>Expected: "1 000 kr"
  Received: "1 000 kr"
  </code></pre>
  
  <p>I've tried assertion with <code>.toBe()</code> as well, giving the same result.</p>
  
  <p>What is the correct way to assert the two strings above?</p>
