title: √ not recognized in Terminal
body: <p>For a class of mine I have to make a very basic calculator.  I want to write the code in such a way that the user can just enter what they want to do (ex. √64) press return and get the answer.  I wrote this:</p>
  
  <p>if '√' in operation:
      squareRoot = operation.replace('√','')
      squareRootFinal = math.sqrt(int(squareRoot))</p>
  
  <p>When I run this in IDLE, it works like a charm.  However when I run this in Terminal I get the following error:</p>
  
  <p>SyntaxError: Non-ASCII character '\xe2' in file x.py on line 50, but no encoding declared;</p>
  
  <p>any suggestions?</p>
