[XeTeX] char ß with pdflatex and xelatex

[M. Niedermair]

Hi,

I am working on a new package version for the libertine font.
Now I have found a problem.

If I use pdflatex I get other Glyphs for the german ß than when I use 
xelatex.
pdflatex and xelatex both use the type 1 version of the font.

I suppose, it is a problem with the input-encoding.

Does anyone have a tipp for me?
