Chicago: Use title case for volume title

[adunning]

This ensures the correct capitalization of a volume title stored in sentence case, such as:

Knowles, David. The Religious Orders in England. Vol. 3, The Tudor Age. 3 vols. Cambridge: Cambridge University Press, 1959. https://doi.org/10.1017/CBO9780511560668.

I observe when testing with Zotero that, if the language is not set to English, the volume title is not set to sentence case as I would expect. I cannot however seem to find a way to control this in the CSL file: is this a bug in citeproc-js?

Casing is only applied to English titles. This is the expected behavior, as other languages have their own distinct casing rules and do not observe sentence/title casing conventions

[adunning]

I am not seeing the expected behaviour you have described: with my proposed change, the volume title is being converted to title case even if the language is set to a non-English language code. Take this example:

Stotz, Peter. Handbuch zur lateinischen Sprache des Mittelalters. Vol. 1, Einleitung, Lexikologische Praxis, Wörter und Sachen, Lehnwortgut. 5 vols. Handbuch der Altertumswissenschaft, II.5. Munich: Beck, 2002.

Zotero is capitalizing 'und' with text-case="title" on volume-title, which must be a bug.
