title: How to make a java regular expression which matches a word in any language
body: <p>To match a word in english I would use pattern <code>[a-zA-Z]+</code>.</p>
  
  <p>Is there any way how to write a regular expression which will match a word in any language? That is even if the word contains characters like <code>ščžé...</code>. I have no idea what possible characters exist in the world so I don't think that pure <code>[a-zA-Zščžé]+</code> would be enough...</p>
  
  <p>Is there a better way to write this expression?</p>
