Ex17 test file looks strange


#1

Just curious - per the lesson I echo to the test.txt file this string: “This is a test file”.
But when I view the file in Atom, it looks this way: ??T h i s i s a t e s t f i l e".
Why?


#2

I just looked at the file with another text editor, and it looks normal, so this is something that Atom does.
