I was wrong. JtR does indeed try to use your Extra characters to look
up likely adjacent ones, which results in misbehavior when these
characters are out of range (CHARSET_MIN to CHARSET_MAX).
As you've found out, JtR 1.7.0.1+ correctly detects this problem but
produces an incorrect error message. I will fix that.
The correct solution for you is to rebuild JtR with the CHARSET_*
settings that I had provided in an earlier posting. Yes, you'll have to
generate a new .chr file, too.
Thanks,
