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:
Something goes wrong with the cite key and i am left with the characteristic (?) in the resulting pdf.
Rstudio is version 1.4.1717 and Zotero is the latest beta update.
Happy to try to provide the MWE if needed!
