(In most fonts, the double quotes are identical to two single quotes side-by-side. E.g., in Times-Roman, quotedblleft is defined in terms of two calls to the same subroutine that draws quoteleft.) Only when copying text from a PDF will you see the difference, by getting one double-quote character vs. two single-quote characters.
