Ok, I filled issue #20614 to track these bugs with __cleanenv=True.
Serhiy>print() can be used during Python exit in destructor if destructor called before cleaning up the builtins and sys modules and encoding module with the encoding of sys.stdout.
Serhiy>Cleaning up the builtins and sys modules are delayed after wiping other modules, this decreases the chance of print() failure.
Ah ok. I tested with a codec implemented in Python, it works well. So it is very specific to test_cleanup() which hack builtins and sys modules to keep a reference their.
I don't see anything else to do, I close the issue.
