If you are using Windows 10, the smiley and other characters won't be displayed correctly ( bcoz Windows 10 got a new console). To make them show correctly do the following:
1. Right click on the top window border of the console,
2. Check "Use Legacy Console" option,
3. Close the game and rerun.
Note: this is a setting for the console not just for the game, if you want the Windows 10 default console back, uncheck this option from any running console.
