Copying here the comment I posted on the other ticket you opened:

Carol, didn't I already answer that question here: https://bibbase.userecho.com/en/communities/1/topics/396-how-do-you-display-non-ascii-characters-such-as-the-degree-mark ? Or do you mean how do you use a text editor to add unicode characters into a bibtex file? That depends on your editor and operating system, but presumably the easiest would be to copy and paste that character from the web somewhere, e.g., here: https://en.wikipedia.org/wiki/Degree_symbol. Here is the symbol itself for your convenience: °

You can just literally copy&paste the degree symbol from the text above. You don't need to use any special character codes.

Then there is something wrong in your bibtex entry. The Paper link, as the name suggests, is supposed to point at the paper itself (PDF or similar). Look for a "url" field in your bibtex and see what it points at. You can also point me to your website where you are using this and I can take a look, too. In general though if you really don't want a paper link, then just don't include a url field in your bibtex entry.

Let me know if you have it live somewhere on a web page where I can look at it. Sometimes it's necessary to add

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

to the head of your page's html, see https://bibbase.userecho.com/en/helpdesks/2/tickets/92-accents-in-title-dont-render-correctly#comment-328.

You can use Unicode characters in your publication entries (in BibTex or another source) directly, no special action required.

Strange. I can't reproduce this. In any event, if you give me your zotero username then I can delete the key from your account. Maybe that will re-enable things.

ah, yes, you are right, it's still stored on your bibbase account if you are logged in. If you just want to use your Zotero publications on your homepage then you can first log out from BibBase and then repeat the Zotero flow. It should work then. I'll see that we accommodate this case where a stores zotero key is no longer valid (and then just offer to re-authenticate).

Thanks for reporting.

Hm, this is more of a question on how your papers are organized in your Zotero library than about BibBase. BibBase just receives whatever Zotero exports your data as. Since you group is public though I had a look and found that there "website" entries seem to have different website types set, and that's what the Zotero API seems to use for the "type" field you see in the exported bibtex entries.

You should be able to just change those website types to whatever you want the document type to be in BibBase.

It should work if you re-execute the Zotero flow from the bibbase.org homepage. Have you already tried that?

What I've shown you above is verbatim what the bibbase server receives when requesting your bibtex file. I know it is confusing that you and I when we request that seemingly same URL get a different response, but that's how CDNs work: they actually consist of very many servers distributed around the globe such that users can always get the pages they request as fast as possible, namely by being served by the closest such server. The bibbase server is located in Oregon and may hence be receiving the file from a different server in the CDN of your hosting provider.

Here is a screenshot of me making the exact same request from my machine (in California) and from the bibbase server in Oregon. As you can see the results are different.

So unfortunately there is nothing I can do here until your hosting provider refreshes their CDN cache serving that region in Oregon. I've already tried tricking your provider into refreshing the file by adding extra URL parameters (?something=1). This sometimes works because it's a different URL. But in this case it didn't.
