VS2010 创建的 MFC 程序，用 VS2013 打开后编译出现错误：
C:Program Files (x86)MSBuildMicrosoft.Cppv4.0V120Microsoft.CppBuild.targets(369,5): error MSB8031: Building an MFC project for a non-Unicode character set is deprecated. You must change the project property to Unicode or download an additional library. See http://go.microsoft.com/fwlink/p/?LinkId=286820 for more information.
