I've used the program for about a week, and have noticed that it drops some special characters in some fonts when imposing the pages. I also noticed that some fonts actually changed from the original PDF file to some other font, even tho the font was embedded in the original file. It's a great little program, but i'm not sure i can count on it to convert the PDF files perfectly.
Also, I found if I reconverted the file again the special characters were there...sometimes.
Just some information for potential users...
