The output and thus whether the program runs is irrelevant to the post. They could even output different things, and it wouldn't have changed anything. I did state the point explicitly, and I'll repeat it for you: The only two possible answers are "all of them" or "none of them", since print can't tell the difference between those strings. The only thing I implied is that it's ludicrous to say iso-latin-1 is utilized for all of them.
I wasn't posting a tutorial or documentation; I was addressing someone's post, and a snippet is not necessarily a script.
