[edit] Possible implementation

First version
template< class CharT, class Traits >
std::basic_ostream<CharT,Traits>&
    operator<<( std::basic_ostream<CharT,Traits>& os, const path& p )
{
    os << std::quoted(p.string<CharT,Traits>());
    return os;
}
Second version
template< class CharT, class Traits >
std::basic_istream<CharT,Traits>&
    operator>>( std::basic_istream<CharT,Traits>& is, path& p )
{
    std::basic_string<CharT, Traits> t;
    is >> std::quoted(t);
    p = t;
    return is;
}
