[Boost-users] program_options and unicode

Greetings.

Say I have a situation like this one:

po::options_description visible("Visible options");
visible.add_options()
        ("opt1", "opt1")
        ("opt2", "opt2")
        ("opt3", "opt3")
        ;

po::options_description hidden("Hidden options");
hidden.add_options()
        ("opt4", po::value<string>(), "opt4")
        ;

po::options_description all_options;
all_options.add(visible).add(hidden);

po::positional_options_description pos;
pos.add("opt4", -1);

po::variables_map vm;
po::store(po::command_line_parser(argc, 		
        argv).options(all_options).positional(pos).run(), vm);
po::notify(vm);

Now I want to replace char* argv[] with wchar_t* in order to pass a 
Unicode file name to a Win32 SDK function CreateFile(). What would be, 
in your opinion, an appropriate course of action? I thank you in advance.
