I haven't tried tha latest Epoch yet, but it sounds great. However,
there is one disappointment:

The FAQ only mentions display of 8-bit chars.  What about input? Are
keymaps still only 128 chars long?  IMHO they should be 256 chars,
and additionally, the "meta bit" concept should go away. This way
8-bit chars can be made first-class citizens.

I have modified my Emacs in this way, the changes are relatively minor, and
it works great. The changes are relative to Emacs 18.57, I haven't got
around to upgrading to 18.58 yet.

My Emacs currently uses the dump-time locale to set up which
upper-half characters are printable (and thus bound to
self-insert-command), it would maybe be more reasonable to do this on
a per-invocation or per-buffer basis, if possible?  The same goes for
the syntax classes and sorting behaviour of the upper-half characters.
I assume it's not politically correct to hard-code in Latin-1, for
instance.

The only compatibility problem I have encountered is that the read
syntax \M-x (x is any char) no longer does anything reasonable.  It
could perhaps be made to expand to an ESC followed by x (when
occurring in strings), but I haven't got around to doing that yet.
For now I change by hand occurences of \M-x in .el files to \ex.

What do you Epoch people think, shouldn't this (or something similar)
be put into Epoch?
