I meant leaving the Ö as is or even introducing it, which is always wrong with Bibtex. I'm not using Zotero but Jabref also fixes it. There was an Ö in an author name and when I manually changed it to {\"O} Kbibtex reverted it back to an Ö! It's easy to fix by switching to XeTeX but some editorial systems don't use it and will make your manuscript fail.

I was just hoping that the tool fixes this problem, too. Maybe in a future version.
