Add support for opening file streams from wide character strings
C++17 added new overloads to <fstream> class templates to support
opening files from wide character strings "on systems where
filesystem::path::value_type is not char". This patch adds those
overloads conditional on _wfopen being available, and enables them for
pre-C++17 modes as well.
Add support for opening file streams from wide character strings.
