Sorry, this wasn't the intent.  I simply didn't see the connection
between your original problem and the code you presented, so I
responded to your "this doesn't work in Emacs 23.1".

Let's back up a little: please tell what is the value of
buffer-file-coding-system after you visit the offending files?

Note that Handa-san recommended to set more than just one slot in
standard-display-table in Emacs 23 to solve similar problems:

  ;; For NBSP (U+00A0)
  (aset standard-display-table #xA0
	(vector (unibyte-char-to-multibyte #xA0)))
  ;; For byte #xA0.
  (aset standard-display-table (unibyte-char-to-multibyte #xA0)
	(vector (unibyte-char-to-multibyte #xA0)))
  (set-terminal-coding-sytem 'no-conversion)
  (set-safe-terminal-coding-system-internal 'no-conversion)

Did you set both slots of standard-display-table as shown above?

What encoding does the text terminal expect for Hebrew characters?
