title: Draw labels with split normal and italic faces in euler plot (eulerr)
body: <p>The <code>eulerr</code> library produces a plot with the following code:</p>
  <pre><code>library(tidyverse)
  library(eulerr)
  
  matrix(data = c(T,T,T,F,T,F,T,F,T,T,T,F,F,F,T), ncol=3) %&gt;%
    venn %&gt;%
    plot(
      labels = c(
        &quot;Left&quot;,
        &quot;Right&quot;,
        &quot;Oh, right&quot;),
      main = expression(&quot;Oh,&quot;~italic(&quot;right&quot;))
         )
  </code></pre>
  <p><a href="https://i.stack.imgur.com/09IgZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/09IgZ.png" alt="enter image description here" /></a></p>
  <p>I need to have italic font in the labels, but only partially. I would like the third label to be formatted like the title: Oh, <em>right</em>.</p>
  <p>I have tried a variety of permutations of <code>paste</code>, <code>expression</code>, <code>bquote</code>, <code>substitute</code>, while setting <code>label =</code> but to no avail.</p>
  <p>Ideas?</p>
