*.CFF might frighten some of you, but have no fear I have an answer!

My experience has thought me that the best software to user for cff font is FTMaster from Altsoft .
You can use FTMaster to convert cff files to ttf or otf and edit them with the font editor that you are familiar with.
FTMaster can also help you extract the fonts form pdf files if the font is not protected or identified as protected.
Extracting fonts from PDF files as stated on the software webpage.
