Gitlab CI locales and encodings

When running stuff using gilab CI, sometimes your run into issues related to different environments.

Reading file and unicode

Some time ago I had an issue about python, unicode and docker. Go here for result and links.

This time it is related to installing pip packages

I do a generic install of packages

$ pip3 install -r requirements.txt
...
Collecting urwidtrees (from -r requirements.txt (line 2))
...
  locale.Error: unsupported locale setting

I use my own generated docker instance at registry.gitlab.com/moozer/docker-deb-pip:latest.

Adding explicit locales work.

before_script:
- export export LC_ALL="C"
- pip3 install -r requirements.txt
