There was probably a character sequence in the binary file
to put your terminal into an alternate character set mode.
For example try:

  tput smacs; echo abcd; tput rmacs

If your terminal is messed up, the `reset` command
(even if you can't see what you're typing), will fix things.

Also note the `cat -v` and `od -Ax -tx1z -v` coreutils
commands for viewing binary files.

cheers,
Pádraig.
