title: Replacing special character from a String in Android
body: <p>I have a String as folder/File Name. I am creating folder , file with that string. This string may or may not contain some charters which may not allow to create desired folder or file </p>
  
  <p>e.g </p>
  
  <pre><code>String folder = "ArslanFolder 20/01/2013";
  </code></pre>
  
  <p><strong>So I want to remove these characters with "_"</strong> </p>
  
  <p>Here are characters</p>
  
  <pre><code>private static final String ReservedChars = "|\?*&lt;\":&gt;+[]/'"; 
  </code></pre>
  
  <p>What will be the regular expression for that? I know replaceAll(); but I want to create a regular expression for that. </p>
