Returns the internal pathname in native pathname format, converted to specific string type. Conversion, if any, is specified in todo.

1) All memory allocations are performed by a.
2) The encoding in the case of `u8string()` is always UTF-8.

### Parameters

(none)

### Return value

The internal pathname in native pathname format, converted to specified string type.

### Exceptions

May throw implementation-defined exceptions.

### Example

Run this code

    #include <clocale>
    #include <cstdio>
    #include <experimental/filesystem>
    #include <fstream>
    #include <iostream>
    namespace fs = std::experimental::filesystem;

    int main()
    {
        std::setlocale(LC_ALL, "en_US.utf8");
        std::locale::global(std::locale("en_US.utf8"));

        fs::path p = fs::u8path(u8"要らない.txt");

        // native string representation can be used with OS APIs
        std::ofstream(p) << "File contents"; // this uses operator string()
        if (std::FILE* f = std::fopen(p.c_str(), "r"))
        {
            int ch;
            while ((ch=fgetc(f))!= EOF) putchar(ch);
            std::fclose(f);
        }

        // multibyte and wide representation can be used for output
        std::cout.imbue(std::locale());
        std::cout << "\nFile name in narrow multibyte encoding: "
                  << p.string() << '\n';

        std::wcerr.imbue(std::locale());
        std::wcerr << "File name in wide encoding: "
                   << p.wstring() << '\n';

        fs::remove(p);
    }

Possible output:

    File contents
    File name in narrow multibyte encoding: 要らない.txt
    File name in wide encoding: 要らない.txt
