We open our files in binary mode:
So I think a NUL character is fine. In regards to the C++ output
convention is that is the C++ standard or merely just the common
practice among implementations?
In regards to ios::skipws that is not on by default. When I had a
formatted string written to the file, "Crazy Kittens", I would get back
Crazy if I did turn ios::skipws on.
