title: How can I do inline formatting (bold and underline) for PDF generated by Prawnto in Rails?
body: <p>I generate a PDF file using Prawn and the Prawnto plugin in my rails application.</p>
  
  <p>I create a standard form with a standard textarea, and submit that as the body of the PDF file.</p>
  
  <p>However, I need to be able to format words and sentences with:</p>
  
  <ul>
  <li>bold</li>
  <li>underline</li>
  <li>maybe different type sizes</li>
  </ul>
  
  <p>I want to be able to do it from within the textarea input box.  Right now, because I use prawnto, I basically am genering a view which outputs what is in the textarea.</p>
  
  <p>But if I put, say, <b>bold</b> in the text area, it doesn't format, it just renders.</p>
  
  <p>How do I do this?</p>
