In text annotations the lines can be wrapped,
but in bookmarks or in the document information
my AR versions do not support this (AR4/Linux, AR5/Linux).

You can try:

\documentclass{article}
\usepackage{hyperref}
\pdfstringdefDisableCommands{%
  \edef\\{\string\r}%
}
\hypersetup{%
  pdftitle={Hello\\World}%
}
\begin{document}
Test for unsupported carriage return in document information.
\end{document}

But AR5/Linux and gv display a dashed rectangle instead, and
pdfinfo 0.92 ignores all after "Hello".

The PDF specification explicitly says for the /Contents of
text annotations:
| Carriage returns may be used to separate the text into
| paragraphs.

In the description of the document information, however, this
sentence is missing. Therefore I would say, that line breaks
should not be used here.
