[Qemu-devel] [RFC PATCH v2 11/11] QMP/qmp.py: set locale for exceptions to display non-ascii messages correctly

[Tomoki Sekiyama <tsekiyam@redhat.com>]

qemu-ga in Windows might return error message with multibyte characters
when the guest OS language is set to other than English. To display such
messages correctly, this decodes the message based on locale settings.
