Avoid Boost.Nowide by using std::filesystem::path?

[peter-jansson]

If C++ 17 is ok, maybe Boost.Nowide can be avoided if std::filesystem::path can be used to read/write files with non-ascii names, e.g. on Windows? I believe std::filesystem::path::value_type is wchar_t on Windows.

I like the idea. I already use std::filesystem in branches.
