title: R-markdown figures captions in greek text
body: <p>I am trying to write a report in R markdown and use the Greek language instead of English although in most parts of the report (plain text, figure text etc.) the language is implemented correctly in the figure captions the text returns the format: &lt;U+0391&gt;&lt;U+03BD&gt;a&lt;U+03BB&gt;&lt;U+03BF&gt;&lt;U+03B3&gt;&lt;U+03AF&gt;a...... instead of actual greek text.</p>
  <pre><code>```{r, echo= FALSE, message=FALSE, warning=FALSE, fig.cap=&quot;Αναλογία φύλων του \\textit{Juniperus drupacea} στο όρος Πάρνωνας, αριθμός ατόμων που ελέγχθηκαν: 488, αριθμός περιοχών δειγματοληψίας: 11, Θ: Θυληκά, Ν: νεαρά, Α: αρσενικά.&quot;}
  </code></pre>
  <p>i have set my local system into Greek, using Xelatex as an Enginge, PDF-Cairo but the problem keeps coming up.
  Any ideas??</p>
  <p>Thank you in advance!</p>
