I try to define the name of a document and to use this name in hyperref resp. as the file's properties etc., but for some reason the pdftitle and the pdfkeyowrd option seem to clash with the line break, is there a way to circumnavigate this issue, thanks?
\documentclass[ngerman]{scrartcl}
\usepackage[english,ngerman]{babel}
\usepackage[utf8]{inputenc}
\newcommand{\Titel}{\mbox{Line 1} \\ \mbox{Line 2}}
\usepackage[ pdftex,
pdftitle={\Titel}, % -->crash
pdfkeywords={\Titel}, % -->crash
pdfpagelabels]{hyperref}
\begin{document}
\begin{flushright}
\Titel
\end{flushright}
\end{document}
\\
is not allowed in a PDFString
