title: Regex: what is InCombiningDiacriticalMarks?
body: <p>The following code is very well known to convert accented chars into plain Text:</p>
  
  <pre><code>Normalizer.normalize(text, Normalizer.Form.NFD).replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
  </code></pre>
  
  <p>I replaced my "hand made" method by this one, but i need to understand the "regex" part of the replaceAll</p>
  
  <p>1) What is "InCombiningDiacriticalMarks" ?<br>
  2) Where is the documentation of it? (and similars?)</p>
  
  <p>Thanks.</p>
