c++ - How to convert UTF-8 std::string to UTF-16 std::wstring?

Question

If I have a UTF-8 std::string how do I convert it to a UTF-16 std::wstring? Actually, I want to compare two Persian words.

Answer 1

This is how you do it with C++11:

std::string str = "your string in utf8";
std::wstring_convert<std::codecvt_utf8_utf16<char16_t>> converter;
std::wstring wstr = converter.from_bytes(str);

And these are the headers you need:

#include <iostream>
#include <string>
#include <locale>
#include <codecvt>
