Well, there's an immediate problem if the file contains any NULL bytes,
which most non-text files do - the code will instantly stop on them.
There may be a faster way using a getline() loop, based on the fact that
many bytes are not \0, but I'm not sure that you'd actually lose much
overhead, given that the stream is likely to be buffered?

I think that the code given is probably the simplest that is actually
guaranteed to work.

Please tell me if I'm being an idiot of course!
