BTW, is there any reason the OP can't simply use SHOW RAW?

I haven't looked at it too clisely, but you have to remember that you
are passing it to the shell for execution, and not typing it at the
command line, so you may need to escape the backslashes one more level.

Remember, in order to do something like:

    echo '\033'

you need to escape the backslash to get the shell to see it:

    sh -c "echo '\\033'"

(Note: I have not actually verified the above, as I'm not on a *nix
box at the moment.)
