    Amend previous commit
    
    The utf8 conversion is only used in the Windows specific section so there's no
    need to define an overloaded function on std::string in this case.
    Also CMakeLists.txt doesn't require the MingW specific library name setting
    for boost::filesystem. Just removing the hardcoded one allows the build to
    pick the right name up from the Boost_LIBRARIES variable.
