How to copy text including special characters to clipboard using C and WinAPI?

I'm trying to make little c program that copies text to clipboard. I found this question asked on this website. Programs code:

const char* output = "Test";
const size_t len = strlen(output) + 1;
HGLOBAL hMem =  GlobalAlloc(GMEM_MOVEABLE, len);
memcpy(GlobalLock(hMem), output, len);
GlobalUnlock(hMem);
OpenClipboard(0);
EmptyClipboard();
SetClipboardData(CF_TEXT, hMem);
CloseClipboard();

This program does copy text to clipboard. But i need it to copy 2 lines. So i try this:

const char* output = "Test1\nTest2";

But it gets copied as literal. How can i fix this code so result would be:

Test1
Test2

rather then:

Test1\nTest2
