Second italic word in title gets upper case in BibLatex export

What happened?

In my Zotero library, I have entries containing species names which are composed of an upper case genus epthet and a lower case species epithet. Both should be in italics.

In the Zotero title field, it looks like this: Kairomone response in <i>Thanasimus</i> predators to pheromone components of <i>Ips typographus</i>

In my file that I export via Better BibLaTeX, I get the following: title = {Kairomone Response in {{{\emph{Thanasimus}}}} Predators to Pheromone Components of {{{\emph{Ips}}}}{\emph{ Typographus}}} Note the upper case last word. I attached the output *.bib file.

Exported Items.bib.txt

I expect it to be lower case and both word to be in one \emph-command: {\emph{Ips typographus}}

Thank you for your quick reply to my opened discussion https://github.com/retorquere/zotero-better-bibtex/discussions/3014#discussion-7271360

I can understand the surprise, but that is actually correct. Bib(La)TeX expects Title Case titles, and since typographus is not case-protected, it gets converted to Title Case. For things like proper nouns in all-lowercase, you will want to have something like

Kairomone response in <i><span class="nocase">Thanasimus</span></i> predators to pheromone components of <i><span class="nocase">Ips typographus</span></i>

that's not pretty, but this is how Zotero expects it. Your original input would also have gone wrong if you render it to a Title-Casing style with Zotero itself (I believe Chicago does this), and the way to protect against it is this same way.

If you want to have all <i>...</i> behave like <i><span class="nocase>...</span></i>, I can write you a postscript that does that during export.

You can turn that behavior off if you want to though:

Ah, I see. That makes sense.

I can live with the suggested workarounds for now. However, I guess all biologists out there will sooner or later run into this issue. Since the case-changing behaviour does make sense, the cleanest solution would probably be to have an option in a future version to suppress case-changing for italicized words, like you proposed.

Many thanks for pointing this out! It would have taken me a long time to figure it out.

[retorquere]

I am not adding an option to suppress case-changing for italicized words. I would be happy to post a postscript that does it though, that would just be added to https://retorque.re/zotero-better-bibtex/exporting/scripting/index.html

[eberlejonas]

Sounds good to me. This would be much appreciated, since we are talking of hundreds of papers. Thanks!

mind that this only works for BBT export. If you render your bibliography in Word or LibreOffice in a title-case style, that will still uppercase the T.

That works perfectly! Thank you!
