Error C2220 happening when system language is not English #8

Hi,
The tutorial is awesome, but when I built the project, some C2220 errors happened and I can't build successfully. Finally, I figure out that I use simplified Chinese Windows system language and it might change some characters within the files. So you might want to tell people to use English system when they clone the project.
By the way, I figure out this problem by save the files as encoding and set the file to be unicode.
