If the user creates his Unity project under a folder that contains a "," Unity console will generate 'System.IO.DirectoryNotFoundException: Could not find a part of the path' error messages.

1. Create a folder and rename it to contain a ","
2. Open Unity, create a new project and nest in the previously create folder
3. Notice errors.

N.B.: My folder, for reference, is called: I'm SPECIAL, I have characters (☆ミ) and emoticons (😇)

System.IO.DirectoryNotFoundException: Could not find a part of the path '/Users/pedroa/Desktop/UnityFolder/I'm SPECIAL'.
