UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 633: ordinal not in range(128)

Diffbot is not currently installing under a fresh (docker) install of python3/ubuntu, perhaps there is an unstated dependency / or one I missed?

You should be able to replicate with the following Dockerfile

FROM ubuntu:14.04

RUN apt-get  -y --force-yes update
RUN apt-get update && apt-get install -y \
  python3 \
  python3-dev \
  python3-pip

RUN pip3 install diffbot

The same problem occured here Kronuz/pyScss#308. The solution is described in the closing commit Kronuz/pyScss@71e8a89 and a temporary workaround using ENV LC_CTYPE C.UTF-8 in the dockerfile works as an interim workaround suggesting the underlying problem is likely similar.
