Pass wchar_t* to std::ifstream::open to prevent implicit UTF16->ANSI

The previously passed `const std::wstring&` was implicitly converted to an `std::filesystem::path`.
That library is still considered experimental in the used libc++ release, so it should be avoided outright.
Even worse, this version performs an implicit UTF16->ANSI conversion, breaking all efforts of consistent Unicode usage.
