Adding Unicode support to VS2015 C++ project

Hello! I have a VS2015 C++ project. This application can be run with the following commandline: C:\wagon\app\win32\release\[login to view URL] -data C:\wagon\stuff\ansi\[login to view URL] -desc C:\wagon\stuff\ansi\[login to view URL] -stop 2 -output C:\wagon\stuff\[login to view URL] Currently, this application expects ANSI files for input (input examples can be found in the subdirectory wagon\stuff\ansi). This works perfectly fine. I would however like to have it changed so that it can work with Unicode files (I have attached sample inputs in the subdirectory wagon\stuff\unicode). To test this, please use the following commandline: C:\wagon\app\win32\release\[login to view URL] -data C:\wagon\stuff\unicode\[login to view URL] -desc C:\wagon\stuff\unicode\[login to view URL] -stop 2 -output C:\wagon\stuff\[login to view URL] Please take a look at the attached screenshot. You can see that this function only deals with ANSI. I need to have this solution converted to deal with Unicode. I don't know what should be changed to make this work, but I hope I have provided a good example set to test it (wagon\stuff\unicode) The solution can be downloaded here: [login to view URL] Thank you.
