in my Bibtex file i name the Author:
author={R{\"o}{\ss}ler, Irene and Ungerer, Albrecht},
but in the literature list it strangely outputs this:
[Rößler und Ungerer 2012] RÖSSLER, Irene; UNGERER, Albrecht:...
where the second RÖSSLER should also be RÖßLER
Update2: MWE

scrartclinstead ofarticle. Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with\documentclass{...}and ending with\end{document}. – Marco Daniel May 13 '13 at 18:27.bibfile. I suspect you have an extra space there, perhaps. – Alan Munn May 13 '13 at 18:35.bibfile contains a~after{\ss}. This will give a hard coded space; it should simply be removed. – Andrew Swann May 13 '13 at 18:51ben\"otigtevery time, check out Automatically change é to 'e – most convenient setup for accented letters?. – doncherry May 13 '13 at 18:55
