error: no operator "+" matches these operands

std::filesystem::path::u8string() returns an object of type std::string, so it should be ok to use operator+ to cat a const char* with std::string... I'm not sure why this ce happens. Maybe it's caused by compiler config. Could you please setup a new project and test the following code?

#include <iostream>
#include <filesystem>

int main()
{
    std::cout << ("test output" + std::filesystem::current_path().u8string() + "  test output") << std::endl;
}

Okay thanks for help, I had to change only C++ Language standard to ISO C++ 17 standard(std:c++17)
