I think the part that gives inspecting an object well-defined behaviour is
http://eel.is/c++draft/basic.types#general-4. I'm not 100% sure, though. There
might be something more explicit (I was hoping someone here knows).
https://eel.is/c++draft/cstring.syn#3 also states that "[The `memcpy` and
`memmove`] functions implicitly create objects
([[intro.object]](https://eel.is/c++draft/intro.object)) in the destination
region of storage immediately prior to copying the sequence of characters to
the destination", which sounds to me a lot like it's allowed to copy the bytes
_from_ anywhere.
