title: Knitr - stop superscript in R Markdown
body: <p>I need to stop superscript before comma - <code>,</code> or full stop - <code>.</code>. When converting the <code>Rmd</code> file to HTML knitr makes comma superscripted as well. Example:</p>
  
  <p><strong>example.Rmd</strong></p>
  
  <pre class="lang-none prettyprint-override"><code>MyTitle
  ========================================================
  J.Smith^1, K.John^2, H.Gone^*.
  </code></pre>
  
  <p><strong>example.html</strong></p>
