"UnicodeEncodeError: 'latin-1' codec can't encode character, ordinal not in range" on GCS upload_object_via_stream

[yagodorea]

Summary

I'm trying to upload some CSV files to GCS using libcloud, today I this error:

UnicodeEncodeError: 'latin-1' codec can't encode character '\u201c' in position 628: ordinal not in range(256)

Detailed Information

The encode character and position change with each run, even though the files don't change. I'm not sure what's causing that, CSV files are basically plaintext.

Here's the full stack (some internal code ommitted):

I'm running this from inside a k8s pod in a GKE cluster, trying to write to a GCS bucket.

apache-libcloud version: 3.5.1
python version: 3.8.15
pod image: python:3.8-slim

I'm not sure what are the steps to reproduce it. It's a CSV file generated by pulling some BigQuery schema metadata. It works locally, but when I ran it in the pod it raised this error.
