在vs编译multi-byte character set MFC程序是出现如下错误：
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.
解决方法：查了资料后才知道原来是微软在VS2013中把 multi-byte character set 支持移除了，真是坑人。
