New here but couldn't find this specific question. I am using the citations function new to the visual editor in conjunction with Zotero.
It creates automatic citekeys from the entries in the zotero database, creates its own bib file and then uses that to build the tex document. So far, so incredibly convenient.
The only issue comes when citing an author with a diacritic in their name, for example here:
Incidentally, I am sure it is the diacritic because when I change "Gödel" to simply "Godel" in Zotero, and then have RStudio create a new citekey based on the new "Godel" author, the citation works properly.
