Error with Font Ligatures

Hello, I encountered an issue with pdfbook2 when making a booklet from a T1-Encoded PDF which is using the Lato font:

...
\usepackage[utf8]{inputenc}
\usepackage[default]{lato}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}
...

I am running pdfbook2 v1.4 with

$ pdfbook2 -p a4paper -n -s -o 0 -i 0 -t 0 -b 0 main.pdf

Presumably this has to do with T1 font encodings. pdfbook2 is a great little tool and it would be awesome if this can be fixed!
