title: Doesn't the Quantifier {0,0} mean to exclude character in regex?
body: <p><strong>What i have understood about the Quantifier <code>{}</code>:</strong></p>
  
  <p>The first integer in Quantifier <code>{}</code> means <strong><em>at least</em></strong> and the second integer means <strong><em>at most</em></strong>. So <code>{n,m}</code> would mean at least <strong><em>n</em></strong> and at most <strong><em>m</em></strong>.</p>
  
  <p><strong>What i don't understand:</strong></p>
  
  <p>Similarly, <code>{0,0}</code> means at least zero and at most zero (which is equal to <em>excluding</em> some character). So the Regex <code>/(?=\W{0,0})/</code> should exclude special characters but it doesn't why ? </p>
