The only difference I can see is the codepage used.

The Windows console use codepage 850:

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

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

You can now see the possible cause of the problem.

Try to change the codepage of the console.
