I'm trying to get decoded String from UTF16 encoded String.

Current value of UTF16 is \u5f00\u53d1\u8005 and original string is 开发者 In other words, \u5f00\u53d1\u8005 ==> 开发者 using C++`.

How can I do this using C++?

Assuming you have it stored in a wchar_t array or std::string it's just a matter of correctly setting your environment to deal with wide chars, take this console example:

#include <iostream>
#include <fcntl.h>

int main(){

  _setmode(fileno(stdout), _O_WTEXT);
  const wchar_t str[] = L"\u5f00\u53d1\u8005";
  //std::wstring str = L"\u5f00\u53d1\u8005";
  std::wcout << str;
    
}

It's as simple as that.

To use with mfc particularly maybe you should take a look at MultiByteToWideChar and/or WideCharToMultiByte.

There is also this post in Code Project that may have just what you need.
