Chances are that those cracked passwords are not in fact valid UTF-8.
Maybe they're iso-8859-1. JtR running in incremental mode has no idea
about UTF-8 - it merely tries sequences of octets, some of which happen
to be valid UTF-8 and some not. As you can see, this actually works
well for you because some passwords are in fact not UTF-8.
