title: RTF String Font Size
body: <p>I am a little confused with the <code>RichTextBox.Rtf</code> property. I am inputting a string with a mix of font sizes: <code>Test</code> with font size of 20 and <code>string</code> as font size of 10. However when I look at the <code>Rtf</code> string, I get the following:</p>
  
  <blockquote>
    <p>{\rtf1\ansi\ansicpg1252\deff0\deflang2057{\fonttbl{\f0\fnil\fcharset0 Arial;}}\r\n\viewkind4\uc1\pard<b>\fs40 Test\fs20 string</b>\fs20\par\r\n}\r\n</p>
  </blockquote>
  
  <p>That suggests the font size is 40 and 20 - can anyone tell me why they differ?</p>
