调研方向

从 libcloud/storage/base.py 中的 upload_object_via_stream 和 libcloud/storage/drivers/s3.py 中的 S3 驱动路径开始，然后跟踪请求通过 libcloud/common/base.py 和 libcloud/http.py 的准备过程。在报告中的 Python 和容器环境中，使用包含非 Latin-1 字符的 CSV 重现该失败。完成标准是上传能够处理此类 CSV 内容而不出现 UnicodeEncodeError，并为失败路径包含回归覆盖。

描述

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.
