title: How to generate a PDF with non-ascii characters using from_string from python-pdfkit
body: <p>I'm struggling to generate just a simple PDF with non-ascii characters using Python 3.5.2, python-pdfkit and wkhtmltox-0.12.2.</p>
  
  <p>This is the easiest example I could write:</p>
  
  <pre><code>import pdfkit
  html_content = u'&lt;p&gt;ö&lt;/p&gt;'
  pdfkit.from_string(html_content, 'out.pdf')
  </code></pre>
  
  <p>This is like the output document looks like: <a href="https://i.stack.imgur.com/W1e1X.png" rel="noreferrer"><img src="https://i.stack.imgur.com/W1e1X.png" alt="non-ascii character incorrectly shown in the PDF"></a></p>
