Uhm, oops, my fault.  There were 8-bit characters in that script that
I didn't mention.  I don't know what you saw, but what you should have
seen was:

    set_titlebar () { echo -n "^[]2;$*^G"; }

Here ^[ and ^G actually have to be real control characters not a ^
followed by a G or [.  To type these into a file in emacs, you can use
C-q C-g for ^G and C-q C-[ for ^[.  If this doesn't make sense to you,
ask and I'll explain in more detail.  You can get the same effect from
a bash prompt with C-q Cv:

  quoted-insert (C-q, C-v)
              Add  the  next  character that you type to the line
              verbatim.  This is how to  insert  characters  like
              C-q, for example. 

Let me know if this doesn't help.
