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.
