yes (where the "not .. and .. " really should contain Unicode (UTF-8)
backquotes and forward quotes.

An alternative that I have not tested for this specific case,
but we have been using when working with German umlauts, French
accents, etc is to allow LaTeX to work automatically with
(many/most) unicode characters *in*  the *.tex file :


in the preamble of your *.tex / *.Rnw document.
