Unicode 错误unicodeescape编解码器无法解码字节...无法在 Python 3 中打开文本文件

我正在Windows 7机器上使用Python 3.1.俄语是默认系统语言，utf-8是默认编码.

看看previous question的答案，我try 使用"编解码器"模块来给我一点运气.以下是几个例子:

>>> g = codecs.open("C:\Users\Eric\Desktop\beeline.txt", "r", encoding="utf-8")
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-4: truncated \UXXXXXXXX escape (<pyshell#39>, line 1)

>>> g = codecs.open("C:\Users\Eric\Desktop\Site.txt", "r", encoding="utf-8")
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-4: truncated \UXXXXXXXX escape (<pyshell#40>, line 1)

>>> g = codecs.open("C:\Python31\Notes.txt", "r", encoding="utf-8")
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 11-12: malformed \N character escape (<pyshell#41>, line 1)

>>> g = codecs.open("C:\Users\Eric\Desktop\Site.txt", "r", encoding="utf-8")
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-4: truncated \UXXXXXXXX escape (<pyshell#44>, line 1)

我的最后一个 idea 是，我认为可能是Windows将一些文件夹(例如"用户"文件夹)"翻译"为俄语(尽管键入"用户"仍然是正确的路径)，所以我在Python31文件夹中try 了它.不过，运气不好.有什么 idea 吗？
