title: Convert all csv files from encodeing ansi to utf8 using python
body: <p>I have python code as below:</p>
  
  <pre><code>import os
  from os import listdir
  
  def find_csv_filenames( path_to_dir, suffix=".csv" ):
      filenames = listdir(path_to_dir)
      return [ filename for filename in filenames if filename.endswith( suffix ) ]
      #always got the error this below code
  filenames = find_csv_filenames('C:\casperjs\project\teleservices\csv')
  for name in filenames:
      print name
  </code></pre>
  
  <p>I meet the error :</p>
  
  <pre><code>filenames = find_csv_filenames('C:\casperjs\project\teleservices\csv')
  Error message: `TabError: inconsistent use of tabs and spaces in indentation`
  </code></pre>
  
  <p>What I need : I want to read all csv files and convert it from encoding ansi to utf8 but the code above is only read path of each csv files. I don't know what's wrong with it?</p>
