appjs openDialog return value is garbled

Question

using appjs-0.0.20-win32-ia32

window.frame.openDialog({
            type: 'save', 
            title: 'Save...', 
            multiSelect: false, 
            dirSelect:true           
            }, function( err , files ) {
               for(var i=0;i<files.length;i++) {
                  console.log(files[i]);
               }

           });

example: 轠ѓ轤ѓ轤ѓlo

This issue happens only in Windows 7 with dirSelect true, Its working correct in Ubuntu 12.04. Also this is working correct if I used the openDialog dirSelect false mode, that is file selection enabled. I tried both 64 bit and 32 bit machines.
