Research direction
Open vshadow/tracing.cpp and inspect line 51, where the Visual Studio 2019 build reports error C2275 for std::wstring. Reproduce the Debug x64 build of the vshadow project and review the surrounding code and the file-encoding warning. Done means the project builds successfully without this error.
