title: python: getfilesystemencoding() returns different value in shell and wsgi
body: <p>When I type 'sys.getfilesystemencoding()' in shell, I got the result "utf-8"</p>
  
  <pre><code>&gt;&gt;&gt; 
  &gt;&gt;&gt; import sys 
  &gt;&gt;&gt; sys.getfilesystemencoding()
  'UTF-8'
  &gt;&gt;&gt; 
  </code></pre>
  
  <p>But when I run in a WSGI script , I got the result "ANSI_X3.4-1968"</p>
  
  <p>So why is it different?</p>
