Hi there, I'm new to the forums so first of all HI!

I have a book which for some reason has every instance of "fl" and "fi" replaced with a question mark. Example:

I said I’d become boring, Kell,” Dockson said. “Not sloppy. I can handle a couple of Ministry ?unkies.”
“Good,” Kelsier said, reaching into his cloak pocket and pulling out a small vial. A collection of metal ?akes ?oated in an alcohol solution within.

We arrived in Terris earlier this week, and, I have to say, I ?nd the countryside beautiful.

I'm new to fixing things like this in Calibre, so I haven't figured out if there's a simple way to fix the text, without having to go through the whole book manually - it's a biggie! Obviously, I can't do a simple find/replace... Anyone got any suggestions for me?
