Emacs 21.1 created the M-x prompt.  Tcsh also creates the funny

You are right.  This fixed my 8 bit meta-ness.  I did not see it when
looking through the news file as I was using search keywords such as
"8" "input" and some other terms I remember being used for this type
of thing.

My environment from the SHELL buffer has this in it (after removing
useless stuff):


It looks like SUPPORTED/LANG is possibly involved, but it seems odd
to remove support for US English to get meta back.

Thanks for the quick response.  I was putting a lot of funny
characters in my buffers.
