Thanks all for your (very efficient) help!
I added this to the env, and now it works:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8

It was fr_FR.UTF-8 before

You'll need to specify the .UTF-8 variant of that, though it need not be en_US.  Python's datetime functions use the configured locale, which when it isn't the UTF-8 variant, outputs incompatible encodings.

Can you set your locale to something US UTF8 and restart your Galaxy.

I guess this is happening because of some dates do are not in UTF-8.
