# \emph yields bold-italic using the package “libertine”

How can I make \emph use italics again after loading the package libertine? I suspect that this may be a bug in the font itself. I tried reinstalling the font and upgrading it onto the most recent version. I am using XeTeX and Linux. (Ubuntu)

The font seems to have issues, see Linux Libertine Initials break emph, which is basically a duplicate, right? –  Martin Scharrer Jun 30 '11 at 13:42
I found the solution. This was a bug and is fixed by now. –  FUZxxl Jun 30 '11 at 13:48
Feel free to post the solution as answer by yourself. Other people might have the same issue. Otherwise please delete the question. Either way, it should not stay unanswered. –  Martin Scharrer Jun 30 '11 at 13:50

The problem is a bug in the font. Upgrading the font to 5.1.3 and removing the old font files solves the problem.

i wonder if you're using the proper encoding: libertine fonts are only available in T1 encoding (under ordinary latex, anyway). The following works for me

\usepackage[T1]{fontenc}
\usepackage{libertine}
...
\begin{document}
here \emph{we} \textbf{are \emph{again}}
...

FUZxxl uses xetex which use the open type version of the fonts and fontspec (and so encoding EU1). –  Ulrike Fischer Jun 30 '11 at 14:30
