Ah, then doing it by hand is the only option, unless you can get someone to re-rasterize the text ;)

Nevermind then--it's not horrible not to care. I'm just trying to find anything that might signal to people that this is a reconstruction, and anachronistic PC-era punctuation is one of them. But it's not a big deal at all.

EDIT: Actually if you're re-rasterizing--even if you can't match the form exactly, I think U+2019 would be "a better kind of wrong". Wrong, but more plausible for the era in which it was created.
