Windows 10, Python v3.6.3, olefile v0.44 UnicodeDecodeError

[Ivan-Castro]

Trying to install olefile through pip install Pillow, I got:

C:\Users\Iván>pip install Pillow
Requirement already satisfied: Pillow in c:\users\iván\appdata\local\programs\python\python36-32\lib\site-packages\pillow-4.3.0-py3.6-win32.egg

During handling of the above exception, another exception occurred:

Do you get the same with "pip install olefile"?

You could first try "python -m pip install -U pip setuptools wheel" just in case.

When I read the error messages, it looks like an exception in pip due to the special character in the user name (C:\Users\Iván), and not an olefile issue. I'll close it, feel free to reopen if you have more evidence it's linked to olefile.
