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

(none)

### Example

Run this code

    #include <cstdio>
    #include <clocale>
    #include <fstream>
    #include <iostream>
    #include <experimental/filesystem>
    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);
    }

Output:

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