title: Filtering out UTF-8 punctuations and symbols from a String
body: <p>What is the best and most efficient way to filter out all UTF-8 punctuation characters and symbols like ✀ ✁ ✂ ✃ ✄ ✅ ✆ ✇ ✈ etc from a String. Simply filtering out all characters that are not in a-z, A-Z and 0-9 is not an option, because I want to keep letters from other languages (ą, ę, ó etc.)
  Thanks in advance.</p>
