title: Convert string to char
body: <p>I get from another class string that must be converted to char. It usually contains only one char and that's not a problem. But control chars i receive like '\\n' or '\\t'. 
  Is there standard methods to convert this to endline or tab char or i need to parse it myself?</p>
  
  <p>edit:
  Sorry, parser eat one slash. I receive '\\t'</p>
