// UTF8-Everywhere is the original behaviour of ghc::filesystem. But since v1.5 the windows
// version defaults to std::wstring storage backend. Still all std::string will be interpreted
// as UTF-8 encoded. With this define you can enfoce the old behavior on Windows, using
// std::string as backend and for fs::path::native() and char for fs::path::c_str(). This
// needs more conversions so it is (an was before v1.5) slower, bot might help keeping source
// homogenous in a multi platform project.
