Docker launcher fails with message «/pups/lib/pups/cli.rb:15:in `split': invalid byte sequence in US-ASCII» then container *.yml file contains non-ASCII symbols

How exactly to go about this?

Someone had an “é” in their hostname earlier today and the same error came up.

I tried changing a few settings within the yaml file to france, but same error occurred.

Which setting to change, and where?

I tried to change:


from .english to france

and


to fr_FR.UTF-8

separately and in combination.
