title: Escaping an apostrophe in a character literal
body: <p>Could you please tell me how can one escape an apostrophe. </p>
  
  <p>I need it to process non apostrophe characters through file operations so when I encounter an apostrophe(<code>'</code>) I can't just give <code>ch!='''</code>. It doesn't work. Could you please tell me the right format. Thank you..:)</p>
