filesystem::path & wide char strings?

Hello, I want to use the filesystem::path class for a project I'm working on, but I need to support wide character strings in the path names. I might be missing something, but it seems that path only supports std::string. Is this because of a portability issue or what is the rationale for not using something like basic_string<CharType>? Are there any plans to provide support for wide character strings in the future? Thanks, Cody Batt
