The title says it. See for example the docs for atomics_to_string/2. I’d assume that the original text says atomics_to_string(List, '', String) but the source of the page has the following snippet:
Equivalent to <code>atomics_to_string(List,” ,
String)</code>.
Note that the line break is in the source, too. Maybe related?
Another place with identical problem is the docs for atomic_list_concat/2.
I am really sorry that I don’t have the time to investigate on my own, so I will just report it at the moment.
