title: Find string with special char using regex
body: <p>I need to scroll a List and removing all strings that contains some special char. Using RegEx I'm able to remove all string that start with these special chars but, how can I find if this special char is in the middle of the string? </p>
  
  <p>For instance:</p>
  
  <pre><code>Pattern.matches("[()&lt;&gt;/;\\*%$].*", "(123)") 
  </code></pre>
  
  <p>returns true and I can remove this string</p>
  
  <p>but it doesn't works with this kind of string: 12(3). </p>
  
  <p>Is it correct to use \* to find the occurrence of "*" char into the string?</p>
  
  <p>Thanks for the help!
