Passing the argument `text=True` to `subprocess.run()` is supposed to mean that any captured output of the called process is automatically decoded and retuned to the user as test instead of bytes.

However, if you give a timeout and that timeout expires, the raised `subprocess.TimeoutExpired` exception will have the captured output as as bytes even if text mode is enabled.

Test output:
bash-5.0$ python3 test_subprocess.py
