why Suddenly ??

Reproduce the gsutil cp command using the listed Google Cloud SDK 276.0.0, gsutil 4.47, Python 3.7, and Amazon Linux 2 versions. Start with gslib/gcs_json_media.py, gslib/utils/text_util.py, and gslib/daisy_chain_wrapper.py around the traceback; done means the GCS-to-S3 copy completes without the UnicodeDecodeError.
