Yes, pdf a’s code of some kind is indeed ends with a space, and that space is mandatory. Who let uncle bob specify anything, anything at all?

That's pretty common. I've never seen a magic number that wasn't stored as a packed u32. Just makes it easier to compare and have as part of a header struct

@12bitfloat so common that wikipedia needed to clarify that right then and there?

@kiki Yes, because the space might be overlooked accidentally

Do you actually think people store stuff in 3 bytes?

For a file siggy? Not confusing if you read it in hex, because you can *see* the space ($20464450).

But when you render them as text, that's the first mistake, because you shouldn't. What if the siggy was something jackoffesque? "NICETITS" ($41CE7175) would read "uqÎA", which is just wrong on an ethical level.
