A few new annoyances. Of note is the new warning for an unspecified
encoding when opening a text file, which actually does indicate a
potentially real problem; see
https://www.python.org/dev/peps/pep-0597/#motivation

Use LC_CTYPE to determine an encoding to use for interpreting QEMU's
terminal output. Note that Python states: "language code and encoding
may be None if their values cannot be determined" -- use a platform
default as a backup.

Hi, I sent a PR for this (and an additional fix that is needed as of
yesterday):

https://lists.gnu.org/archive/html/qemu-devel/2021-09/msg04477.html

Please drop this patch and prefer that series.
