The only difference I can see is the codepage used.

The Windows console use codepage 850:
http://stackoverflow.com/questions/1259084/what-encoding-code-page-is-cmd-exe-using

Instead the default codepage of Windows for western languages is 1252.


Now, "fate" is that (Python console):
>>> '\xe8'.decode('cp1252').encode('cp850')
'\x8a'
>>> '\xde'.decode('cp1252').encode('cp850')
'\xe8'


You can now see the possible cause of the problem.


Try to change the codepage of the console.
