CSL name parsing

[Emiliano Heyns]

Is there a way that I can "protect" a dropping particle? I am concretely looking for a way to enter data into Zotero such that

// run `node index.js` in the terminal

const CSL = require('citeproc');

const name = {

family: 'Condercet',

given: 'Marquis de',

}

CSL.parseParticles(name)

console.log(name)

would return
{ family: 'Condercet', given: 'Marquis de' }
rather than
{ family: 'Condercet', given: 'Marquis', 'dropping-particle': 'de' }

ISTR that it used to be possible to enter

[Condorcet]["Marquis de"] 

to do this, but if that ever worked, it does not now.
