We had no unit test coverage for the console-log command
so this adds a simple test. It unfortunately does not
recreate the original UnicodeEncodeError bug though, but
it gives us some test coverage anyway.
This change also adds docs on how to resolve bug 1746534
by configuring the environment for UTF-8 as noted in
the revert change Iaeec1e74262a35f3de3c81f7013835a6aa6f9029.
The documentation added here is shamelessly copied from
Click [1] which was found via the PEP 538 docs [2].
