For en, the localized quotes match what Quoted would produce,
so the Quoted is passed to citeproc as a Span ("",["csl-quoted"],[])
and flipflopping and localization occur.

Foo [@a 50].
^D
Foo (Aristotele, n.d., 50).

Aristotele. n.d. “Metafisica Et ‘Physica’.”
```

For cs, there is no such match, so the Quoted is left alone
and has the same effect it would have elsewhere in a pandoc document.
