title: é and other special characters crash my app when being passed into a URL
body: <p>I've been doing some searching and can't seem to be sure or work around when special characters are included in text.</p>
  <p>How would I go about cleaning up special characters within Swift?</p>
  <p>The scenario is I have a function</p>
  <pre><code>GoogleAPI().getBusinessInfo(googleUrl: &quot;https://maps.googleapis.com/maps/api/place/findplacefromtext/json?input=\(business.alias)
  </code></pre>
  <p>This function will then make an API call to get data, nothing fancy. However, I'm crashing when I come across é.</p>
