The 8 bits display was controlled in Epoch4.0 with variable "ctl-arrow",
but now, in Epoch4.2, it is handled with variable "meta-printable". 
Setting "ctl-arrow" to anything but t or () is experimentally a bad idea. 
Anyway, "viewer" manages it for you.  You don't need to do that yourself. 
So the only thing I can think of lies in this excerpt from the
README.viewer file:

>>  Epoch needs a lit hack to be able to display the whole (f)math font,

As you see, Lucid emacs needs a similar hack.  The package "viewer" uses an
embryonic Epoch/Lucid-portable package called "portable".  You might want
to check that your version is up to date with the one on babar.inria.fr
(138.96.24.21) in pub/emacs.  Sorry, but there is no version number (yet?).
