I gave your patch series a try, but now I see a lot of these messages in
the output:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
	LC_ALL = (unset),
	LC_TIME = "en_DK.UTF-8",
	LANG = "en_DK.UTF-8"
    are supported and installed on your system.

Is it really a good idea to use the host locale in the guest, too? ... I
don't think so... at least you should make sure that *all* possible
locales are installed in that case.

"gmake check" then also finally failed:

Note that if you just wanted to fix the python3 utf-8 problem with this
patch here, there is a separate fix available for that problem already:
