title: Custom URL scheme to open text in whatsapp from mobile browser, newline / line break not working
body: <p>I am using the following code: (jquery)</p>
  
  <p><code>window.open("whatsapp://send?text=Hello World!")</code></p>
  
  <p>To open and share a message from the mobile browser, this documentation can be found here:
  <a href="https://www.whatsapp.com/faq/android/28000012" rel="noreferrer">https://www.whatsapp.com/faq/android/28000012</a></p>
  
  <p>However, I'd like to add a 'newline' somewhere in the message.</p>
  
  <p>I tried: <code>\n</code> <code>&lt;br&gt;</code> <code>&lt;br/&gt;</code> <code>&amp;lt;br&amp;gt;</code> in the message but these do not seem to work properly.</p>
  
  <p><code>\n</code> <code>\r</code> only give me a "space" as well as <code>+</code></p>
  
  <p><code>&amp;lt;br&amp;gt;</code> breaks the sentence off.</p>
  
  <p>Anyone that can give me some insight into how I generate a linebreak in the whatsapp message from a (mobile) browser?</p>
  
  <p>Really stuck here!</p>
