title: Regex to find special characters in a String with some exceptions
body: <p>I just had a similar (but not exact) question answered. Now I need help with the question mentioned below.</p>
  
  <p>I want to write a regex which matches a character if its a non word, non digit and non star (*) character. So, the characters <code>[0-9][a-z][A-Z] *</code> should not match and the others should.</p>
  
  <p>I tried writing <code>[\W[^*]]</code> but it doesn't seem to work.</p>
