How to get a capitalized subtitle in CSL JSON export?

[SmallHollow]

I'm using Zotero 7.0.11 + Better BibTeX 7.05 to create a CSL JSON bibliography that I use with Pandoc. I have entered my bibliographical data into Zotero in sentence case, separating the title and subtitle with a colon as recommended in Zotero knowledge base. Everything works perfectly except the following tiny detail.

I'm using the APA style, where the subtitle is capitalized. For example, "Thinking in jazz: the infinite art of improvisation" should become "Thinking in jazz: The infinite art of improvisation". However, I can't get the subtitle capitalized, it is exported into the CSL JSON like I write it in Zotero. Creating the bibliography in Zotero does capitalize it.

I've read the BBT FAQ, a bunch of GitHub issues and Zotero forums but I can't figure this out.

So my question is: is it possible to configure BBT to export the subtitles capitalized? Or should I edit the bibliographical entries in Zotero? Or should the capitalization be actually handled by Pandoc?

Yes, with a postscript:

if (Translator.BetterCSL && csl.title) csl.title = csl.title.toUpperCase()

but you should leave that to your bibliography processor. If you tell pandoc what style you want, it will do the capitalization while it's generating your bibliography. That's what citation processors are for.

Or should I edit the bibliographical entries in Zotero?

No.

Or should the capitalization be actually handled by Pandoc?

Yes.

Thanks! I will investigate this now with Pandoc (I'm using the latest APA CSL but for some reason Pandoc does not capitalize the subtitle).

Sorry, misread. I'm not sure about subtitle capitalization.
