Overleaf integration - special characters

jemac4
I am using overleaf to write a paper and have integrated it with my zotero bibliography, which is going great except for one problem. I am referencing people from around the world, so naturally some of them have special characters in their name (i.e. ü). However, these are not importing properly into overleaf. How can I make this work?

    How are you using Overleaf with Zotero? Do the authors have the correct characters in Zotero itself?
  • jemac4
    I have synced my Zotero account with overleaf (When you are in a document, you click add bibliography, choose zotero, then put in your zotero login details). In Zotero the characters look correct. Then when I generate the bibliography the special character disappears. For example, "Bünemann" become "Bnemann".

    In that case, it is probably an issue with how Overleaf is handling the information from Zotero and would have to be taken up with them.

    No, it's more complicated than that. see comments starting here for details: https://forums.zotero.org/discussion/comment/263399/#Comment_263399

    Standard bibtex/overleaf expect ISO-8859 encoding and escaped characters, the Zotero API exports utf-8. Currently the only solution is to force Overleaf to use biber/biblatex to process your citations (see https://twitter.com/chrshmmmr/status/785836223260753920 ). Hopefully, in the medium run, the Zotero API will allow charset specification. Overleaf has indicated that they'd then update their integration.

    I just contacted Overleaf support and they promptly replied with a solution. All I had to do was add a couple of packages:

    \usepackage[utf8]{inputenc}
    \usepackage[T1]{fontenc}

    Now it works fine.

    Thank you for your hint with the \usepackage commands, @jemac4. This also worked for me, however, I had to set additionally UTF-8 as standard in the Zotero export properties (properties > export > coding > UTF-8.

    I stumble upon the same issue. I have followed your indications but the accentuated characters are not recognised.
