尝试删除具有Unicode名称的文件夹

#! /usr/bin/env python

import os
import sys

if len(sys.argv) < 2:
     print 'Need to force directories into sys.argv'

     #sys.argv += ["C:\Users\Andy\Desktop"]
     #sys.argv += ["C:\Users\Andy\Desktop\Webpages"]
     sys.argv += ["C:\Users\Andy\Desktop\Downloads (2)"]

def removeEmptyFolders(path):
  if not os.path.isdir(path):
    return

  # remove empty subfolders
  files = os.listdir(path)
  if len(files):
    for f in files:
      fullpath = os.path.join(path, f)
      if os.path.isdir(fullpath):
        removeEmptyFolders(fullpath)

  # if folder empty, delete it
  files = os.listdir(path)
  if len(files) == 0:
    print "Removing empty folder:", path
    os.rmdir(path)

for x in sys.argv[1:]:
     print 'Scanning directory "%s"....' % x
     removeEmptyFolders(x)
     print 'Done.'

我正在尝试使用此代码删除空文件夹，但无法检测到带有»和▶等字符的文件夹。

我尝试将所有路径变量都包含在unicode（）中，但是返回的内容如下：

Traceback (most recent call last):
  File "C:\Program Files (x86)\Wing IDE 101 5.0\src\debug\tserver\_sandbox.py", line 37, in <module>
  File "C:\Program Files (x86)\Wing IDE 101 5.0\src\debug\tserver\_sandbox.py", line 27, in removeEmptyFolders
  File "C:\Program Files (x86)\Wing IDE 101 5.0\src\debug\tserver\_sandbox.py", line 27, in removeEmptyFolders
  File "C:\Program Files (x86)\Wing IDE 101 5.0\src\debug\tserver\_sandbox.py", line 32, in removeEmptyFolders
  File "C:\Program Files (x86)\Wing IDE 101 5.0\bin\2.7\src.zip\debug\tserver\dbgutils.py", line 1491, in write
UnicodeEncodeError: 'cp932' codec can't encode character u'\xbb' in position 54: illegal multibyte sequence

我弄完了

reload(sys)
sys.setdefaultencoding("utf-8")

但这也无济于事。如果没有Unicode（）-s，它就会使我：

Need to force directories into sys.argv
Scanning directory "C:\Users\Andy\Desktop\Downloads (2)"....
Done.
Traceback (most recent call last):
  File "C:\Users\Andy\Desktop\Delete Empty Folders.py", line 959, in <module>
AttributeError: 'file' object has no attribute '_FixGetPass'

而且使用Unicode（）-s ...与不更改默认编码相同。

注意：我正在使用Wing IDE。

我应该切换到Python 3吗？
