I would use both incremental mode and markov mode. Incremental mode (with your own charset file) will find many new cracks. At the beginning of running incremental mode, there shouldn't be many problems with illegal unicode characters (because incremental mode will still have enough information about trigraph frequency...). But the longer you run incremental mode, the more of these problems you will see. Markov mode will produce fewer illegal utf-8 characters than incremental mode. (It will have illegal characters at the end of the word from time to time, but not too many. (Read doc/MARKOV before using it.) While incremental mode will try more likely candidates first, then proceed to less likely candidates, markov mode will produce candidates which match the min./max. Markov mode levels specified. So you might want to start markov mode with a smaller level first, and then try higher levels. (With each level, the run time will increase exponentially.) Of course, when using incremental mode or markov mode, you should set DefaultInternalEncoding = UTF-8 in the [Local:Options] section of your john-local.conf file. Frank
