Using my setup above and assumng my Win locale is en_US.UTF8
This seems like an incorrect assumption. The server is expecting UTF8 yet you are passing it data that is not valid UTF8 bytes. I infer thus your Windows encoding is thus not UTF8.
Suggest you make an even smaller, simpler, and self-contained reproducer and include how you are executing the code. You’ve not provided sufficient detail for someone else to debug your problem.
