title: How do you print unicode symbols in a kable/formattable table?
body: <p>A basic R code chunk to display the problem in an RMarkdown script:</p>
  
  <pre><code>library(formattable)
  
  df &lt;- data.frame(test = c("\u2265", "\u2264", "==", "equals", "!=", "\u2265=", "\u2264="))
  
  formattable(df)
  </code></pre>
  
  <p>Doesn't show any of the unicode symbols after I try and knit to html, instead replacing them with <code>=</code>:</p>
