title: How do I print a Celsius symbol with matplotlib?
body: <p>I want to print an axis label: "Temperature (℃)". How do I do it?
  A snippet is this:</p>
  
  <pre><code># -*- coding: utf-8 -*-
  import matplotlib.pyplot as plt
  x = range(10,60,1)
  y = range(-100, 0, 2)
  fig = plt.figure()
  ax = fig.add_subplot(111)
  ax.plot(x,y)
  ax.set_xlabel('Temperature (℃)')
  </code></pre>
  
  <p>For that last line I have tried: </p>
  
  <pre><code>ax.set_xlabel('Temperature (℃)'.encode('utf-8'))
  
  ax.set_xlabel(u'Temperature (u\2103)')
  
  ax.set_xlabel(u'Temperature (℃)')
  
  ax.set_xlabel(u'Temperature (\u2103)')
  
  ax.set_xlabel('Temperature (\u2103)')
  </code></pre>
  
  <p>I just don't get it. I'm using spyder and running the code from there. </p>
