I mean typesetting from within Texshop with a .bib-file created elsewhere, typically with Bibdesk.

Attached.

I’m using default stuff, I think, with bibtex and not biblatex.

I’ve attached a minimal example. When being more careful, I noticed that the terminal commands 

pdflatex umlauttest
bibtex umlauttest
pdflatex umlauttest

actually also works fine! Why is that? When googling the issue, everybody seem to say that bibtex cannot handle anything else but 7 bits.

When I typeset from within Texshop it also works fine, but Texstudio complains when it tries to run bibtex.
