Thank you very much! --pdf-engine=xelatex did the trick. 

[image: Citation-de-DE-xelatex.png]
lualatex threw up a font error. But I'm happy to use xelatex if it works 
better. 

Do you know whether there any downside to using xelatex? Or is it generally 
to be preferred to pdflatex?

Thanks again for the quick response and help!
Best,
John
