I have an issue with the double quote in my quotation.
Using "OpenGL....."
results in ÖpenGL...
even with \"OpenGL...
the result is the same.
Using \verb results in double quotes in a wrong font type (at least it looks out of place).
\begin{quotation}
"OpenGL (Open Graphics Library) ist eine Spezifikation für eine plattform-
und programmiersprachenunabhängige Programmierschnittstelle zur
Entwicklung von 2D- und 3D-Computergrafik."
\end{quotation}
\shorthandoff{"}
could help, see thebabel
documentation for this command. Though it's recommendable to quote in another way, as the answers show. – Stefan Kottwitz♦ Feb 11 '11 at 18:25
