That should work.

I'm not sure I understand why you'd want to escape those characters,
but because the behavior of echo varies so widely, I usually use
printf(1) for stuff like that.

    osiris:~$ printf 'set w4day=\0140ls \052.4 | cut -d . -f 1-5\0140\n'
    set w4day=`ls *.4 | cut -d . -f 1-5`

Ah, now that I tried it, I see what you are doing.  If you use ''
around that string, you can safely put `` inside it.  So

    echo 'set w4day=`ls *.4 | cut -d . -f 1-5`'

will work fine.
