title: Python error: "LookupError: no codec search functions registered: can't find encoding"
body: <p>I'm running Enthough Canope python distribution in Windows 7 and cannot run working python in a command line.  'python' brings up:</p>
  
  <pre><code>Python 2.7.3 |CUSTOM| (default, Aug  8 2013, 05:30:12) [MSC v.1500 64 bit (AMD64)] on win32
  Type "help", "copyright", "credits" or "license" for more information.
  </code></pre>
  
  <p>but any python command yields:</p>
  
  <pre><code>&gt;&gt;&gt; x = 5
  LookupError: no codec search functions registered: can't find encoding
  </code></pre>
  
  <p>Any idea why this is happening?  I can run ipython perfectly well, but I'm concerned that inability to run basic python is preventing other functionality such as installing new packages.  Grateful for assistance.</p>
