> This is because the `config_templates/default_airflow.cfg` contains a
> non-ascii character and if LC_ALL isnt set to
> `{color:#000000}en_US.UTF-8{color}` or similar Python will assume the file is
> in ascii.
>
> Solution would be to always open the config files as utf-8 regardless of the
> LC_ALL environment variable.

> This worked up until
> [https://github.com/apache/incubator-airflow/commit/16bae5634df24132b37eb752fe816f51bf7e83ca]
> it seems.

> Python versions affected, 3.4.0, 3.5.5, 3.6.0
