Zsh is more happy with meta = bit 8 than meta = extra ESC...
What may be happening here is the tty is set to 7 bit characters (do a
stty -a and look for cs7 or cs8).
Otherwise try "bindkey -m", or "bindkey" and ensure that binding for
meta-key sequences (\M-something) exist.
It isn't awfully clear what to do with the meta key, but it really
seems like sending ESC-<character> is wrong, its almost always used as
a work around when there's a better solution.
That said, the "compose" key comment is very true, so maybe using bit
8 isn't really appropriate either.
Perhaps there is a terminal out there that sets a precident for
indicating the meta key was down that could be implemented? (A late
model VT or something?)
