There aren't enough data in the report, only hints. The image posted
by John indicates a Unixy shell is also involved, so it could be some
issue with the shell itself or its environment (I'm guessing the shell
is either a Cygwin or an MSYS2 Bash, which might mean the Emacs setup
of running them involves setting some coding-systems to UTF-8, for
example).
Then there are 'make' and Python, which are somehow related, but it's
unclear how, due to lack of a complete description.
In general, this looks like UTF-8 output by a subprocess gets decoded
using the Windows codepage. But it's impossible to tell where exactly
is the problem without knowing the details.
IOW, a reproducible recipe, starting from "emacs -Q", and including
only those customizations that are needed for the reproduction, is
necessary to analyze this problem. It is most likely a problem either
with user customization of the coding-systems, or with some subtle
incompatibility between Cygwin/MSYS programs and the native Windows
build of Emacs.
