How to search in unicode using FindWindow in C++ - c++

Question

I am stuck about searching for a Chinese program name while using FindWindowW(NULL, "program name") function.
When I searched for English, it works perfectly.
Can someone give me a clue about how to search using a unicode?
I couldn't figure out yet, can someone guide me how to do?
#include <windows.h>
#include <stdio.h>
int main(){
HWND hWnd = FindWindowW(NULL,L"\uAA5A\uAA4C\uB873\uAB4C\uB6C7");
if(NULL == hWnd){
printf("NotFound!");
}else {
printf("Found!");
}
}

Use the Unicode (wide) version of FindWindow and use wide strings for the search. I also recommend saving the source in UTF-8 encoding and using the /utf-8 compiler switch for the Microsoft compiler; otherwise, the compiler will assume a localized ANSI encoding to interpret the wide string. That's fine if you're localized encoding is a Chinese-variant, but if you're on a US or Western European version of Windows the Microsoft IDE will probably prompt you to save in UTF-16 if you use Chinese characters in string constants:
Example:
#include <windows.h>
#include <stdio.h>
int main(void)
{
//HWND h = FindWindowW(NULL,L"马克"); // works if saved in UTF-8 encoding
// // and compiled with /utf-8.
HWND h = FindWindowW(NULL,L"\u9a6c\u514b");
if(h == NULL)
printf("err = %ld\n",GetLastError());
else
printf("handle = %p\n",h);
}
On Windows I changed the terminal window to a matching Chinese title with title 马克 and this code found the window:
C:\>title 马克
C:\>test
handle = 00000000000B0258
C:\>test
handle = 00000000000B0258
Microsoft's Spy++ tool confirms the handle:
