How to workaround Python "WindowsError messages are not properly encoded" problem?
- by Victor Lin
It's a trouble when Python raised a WindowsError, the encoding of message of the exception is always os-native-encoded. For example:
import os
os.remove('does_not_exist.file')
Well, here we get an exception:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
WindowsError: [Error 2] ???????????: 'does_not_exist.file'
As the language of my Windows7 is Traditional Chinese, the default error message I get is in big5 encoding (as know as CP950).
>>> try:
... os.remove('abc.file')
... except WindowsError, value:
... print value.args
...
(2, '\xa8t\xb2\xce\xa7\xe4\xa4\xa3\xa8\xec\xab\xfc\xa9w\xaa\xba\xc0\xc9\xae\xd7\xa1C')
>>>
As you see here, error message is not Unicode, then I will get another encoding exception when I try to print it out. Here is the issue, it can be found in Python issue list:

The question is, how to workaround this? How to get the native encoding of WindowsError?
The version of Python I use is 2.6.
Thanks.
