title: What is the use of '\b' (backspace)
body: <p>I'm taking a Python class right now, and I just learned about the backspace character.  Like newline (\n), backspace is a special character with ASCII code 8. My teacher couldn't think of a reason to use that, but I'm curious as to how it's used.  Maybe just historical reasons?  When I tried <code>print("Hellow\b World")</code>, I got just got what I expected: <code>Hello World</code>.  </p>
  
  <p>What's the reason for the backspace character, and how might it be used?</p>
  
  <p>Edit: I am aware that it isn't python specific, but when writing the original question I was thinking mainly about Python and forgot this fact.  I've tried to edit to make this more clear.</p>
