Here’s an easy fix for when Docker and the sablon gem don’t want to cooperate: just update your locale.
A problem with the sablon gem occured when our team was developing an application locally in a Docker container. The Docker image based on `Debian Jessie` didn't have `locale` set which caused an encoding issue in `sablon`.
We updated our Dockerfile with the following lines to make sure `locale` is correctly set to `utf-8`:
1

RUN sed -i -e 's/# en_US.UTF-8 UTF-8/en_US.UTF-8 UTF-8/' /etc/locale.gen && \
echo 'LANG="en_US.UTF-8"'>/etc/default/locale && \
dpkg-reconfigure --frontend=noninteractive locales && \
update-locale LANG=en_US.UTF-8
ENV LANG en_US.UTF-8
ENV LANG en_US.UTF-8
ENV LANGUAGE en_US.UTF-8
ENV LC_ALL en_US.UTF-8In Ubuntu, there is the `update-locale` tool which lets you do it quickly: (`update-locale en_US.UTF-8`)
