My terminal is in a weird state

["Mark Wright" <mwright@pro-ns.net>]

I just managed to completely hose my virtual terminal display.  It seems
that non-alpha-numeric characters have been replaced with ascii > 127
characters.  I.e. the '-' becomes the upside down '!'.  I've tried 'reset',
but that doesn't help.  All of my virtual terminals are hosed.  For now I
can telnet in, but eventually I'd like to be able to work at the machine
itself, and I'd like to avoid rebooting if I can.  The problem started after
I droped out of X, after installing Blackbox 5.  Any ideas on how to fix the
problem?
