title: RegEx for ukrainian letters. How to separate cyrillic words by capital letter?
body: <p>I have a String with some cyrillic words inside. Each starts with a capital letter.</p>
  
  <pre><code>var str = 'ХєлпМіПліз';
  </code></pre>
  
  <p>I have found this solution <code>str.match(/[А-Я][а-я]+/g)</code>.</p>
  
  <p>But it returns me <code>["Пл"]</code> insted of <code>["Хєлп", "Мі", "Пліз"]</code>. Seems like it doesn't recognize ukrainian letters('і', 'є'), only russian.</p>
  
  <p>So, How do I have to change that regex to include ukrainian letters?</p>
