PIP does not appear to handle diacritics correctly.

What version of pip are you using? Since (from the path) I guess you
have a 32-bit version of Python 3.5, I assume it's the version which was
installed with that but just check:

pip --version

Hopefully someone here can help, but in fact pip is not part of core
Python: the ensurepip mechanism (which *is* part of core Python)
bootstraps a recent version of pip but it's maintained elsewhere.

So you may need to raise this as a bug on the Pip tracker:
