just one point ?b?b tries the whole hex 00-ff and therefore generates much more possibilites than you will need

for the most "common" utf-8 special cahrs you dont need this whole set, im using a file with

c2c38284969c9fa2a3a4acbab2b3b6bce2177f090a0d818d8f909d

and option --hex-charset to add these for cracking utf-8 chars like € ä ö ü and so on, you can modify this by your own
