title: Converting from NCR to Unicode in R
body: <p>I have some html files (I'm working with them as plain texts) that utilize decimal NCR to encode special characters. Is there a way to convert them conveniently to Unicode using R?<br>
  NCR codes does not always have one-on-one match with unicode and it becomes quite confusing, since <code>&amp;#1123;</code> is equal not to <code>\u1123</code>, but to <code>\u0463:</code></p>
  
  <pre><code>&gt; stri_unescape_unicode("\u1123")
  [1] "ᄣ"
  </code></pre>
  
  <p>and  </p>
  
  <pre><code>&gt; stri_unescape_unicode("\u0463")
  [1] "ѣ"
  </code></pre>
