LibPDF: Fix small bug from #21452

Browse source 
I implemented CFF charset format 2 in 6f783929dd with the note
"I haven't seen this being used in the wild". Now that I have
seen it (0000658.pdf), I can say that this has never worked,
despite me claiming "it's easy to implement".

But now it works!
