Regional language support in VC++ IDE

Hi all,
How can I write following line in typical Unicode enabled
program :

m_bShow.SetWindowText(_T("कददपप"));

I am unable to write the above code as in IDE it is spelled as

m_bShow.SetWindowText(_T("?????"));

Is there any way to do this?

I have typical unicode settings for my VC++ program.
