We recently flipped the switch from v2 to v3 of the boost file system. Now that boost:filesystem::wpath
is no longer a valid type, how do you work with the wide url and boost:iostreams::mapped_file?

With v2 we would

void doSomethingWithMapfile(std::wstring& url)
{
boost::iostreams::basic_mapped_file_params<boost::filesystem::wpath> attribs;

// initialize attribs, including

attribs.path = url;

// create our mapped file

boost::iostreams::mapped_file mapFile(attribs);

// An then do something with the map file.
}
