[luatex] fontspec prevents hyphenation

[Stephan Hennig]

Re-posting example with UTF-8 encoding (hopefully).

\documentclass{article}
%\usepackage[T1]{fontenc}
\usepackage[german]{babel}
\usepackage{fontspec}
\begin{document}
\showhyphens{Deutschland}
\showhyphens{«Deutschland»}
\showhyphens{„Deutschland“}
\end{document}
