Encoding.default_external was chosen over
Encoding.default_internal because File.read is
returning Encoding.default_external, therefore
we should align with it. Alternatively, we could
force both of them to be Encoding.default_internal.

However, ideally this should be determined by different
projects. For example, some projects might want to use
an encoding different to what GitLab is using.

This might not happen soon though.
