Using ↺ on a button in Win32 GUI

I'm making a Win32 GUI application and I want to display the ↺ character on a button.

Normally, I think one would insert a unicode character like this:

HWND button = CreateWindow("BUTTON", "\u27F3",
        WS_TABSTOP|WS_VISIBLE|WS_CHILD|BS_PUSHBUTTON, size - 105,
        size - 29, 100, 24, hwnd, (HMENU)IDI_BUTTON,
        GetModuleHandle(NULL), NULL);

where "\u27F3" is the unicode character described here under "C/C++/Java" http://www.fileformat.info/info/unicode/char/27f3/index.htm

However, when I do this I don't get the arrow character but a different one? What's going wrong?

Thanks!

Well, you could also do this , also this isn't much different from @Mark Ransom answer :- 

HWND button = CreateWindowW(TEXT("BUTTON"), TEXT("\u27F3"),
    WS_TABSTOP|WS_VISIBLE|WS_CHILD|BS_PUSHBUTTON, size - 105,
    size - 29, 100, 24, hwnd, (HMENU)IDI_BUTTON,
    GetModuleHandle(NULL), NULL);

and define a UNICODE in your program like this :- 

 #define UNICODE

Explanation :- TEXT is a macro which expands to unicode equivalent if UNICODE is defined other wise it evaluates to normal ASCII string.

I'm going to shamelessly steal from Raymond Chen's comment and show the corrected code:

HWND button = CreateWindowW(L"BUTTON", L"\u27F3",
        WS_TABSTOP|WS_VISIBLE|WS_CHILD|BS_PUSHBUTTON, size - 105,
        size - 29, 100, 24, hwnd, (HMENU)IDI_BUTTON,
        GetModuleHandle(NULL), NULL);

Naturally the font you have selected into the window will need to support the character.
