#error "DXUT requires a Unicode build. See the nearby comments for details"
//
// If you are using Microsoft Visual C++ .NET, under the General tab of the project 
// properties change the Character Set to 'Use Unicode Character Set'.  
//
// Windows XP and later are native Unicode so Unicode applications will perform better.  
// For Windows 98 and Windows Me support, consider using the Microsoft Layer for Unicode (MSLU).  
//
// To use MSLU, link against a set of libraries similar to this
//      /nod:kernel32.lib /nod:advapi32.lib /nod:user32.lib /nod:gdi32.lib /nod:shell32.lib /nod:comdlg32.lib /nod:version.lib /nod:mpr.lib /nod:rasapi32.lib /nod:winmm.lib /nod:winspool.lib /nod:vfw32.lib /nod:secur32.lib /nod:oleacc.lib /nod:oledlg.lib /nod:sensapi.lib UnicoWS.lib kernel32.lib advapi32.lib user32.lib gdi32.lib shell32.lib comdlg32.lib version.lib mpr.lib rasapi32.lib winmm.lib winspool.lib vfw32.lib secur32.lib oleacc.lib oledlg.lib sensapi.lib dxerr.lib dxguid.lib d3dx9d.lib d3d9.lib comctl32.lib
// and put the unicows.dll (available for download from msdn.microsoft.com) in the exe's folder.
