ParaView Python on Linux needs 4 Unicode width

I typically build a different python with ucs2 support (though I agree UCS4 would be nicer)

# Install python2 with ucs2 https://stackoverflow.com/questions/38928942/build-python-as-ucs-4-via-pyenv
export PYTHON_CONFIGURE_OPTS=--enable-unicode=ucs2
pyenv install -v 2.7.11
pyenv local 2.7.11

# Install pip
wget https://bootstrap.pypa.io/get-pip.py && ~/.pyenv/shims/python get-pip.py

# Install the same numpy paraview uses (as of writing)
~/.pyenv/versions/2.7.11/bin/pip install --user numpy==1.8.1
