I agree, and I vaguely remember that we discussed it looong
ago, and people agreed on displaying them as octal.

But, I've just found that standard-display-table is setup
when we start Emacs with any locale of single byte charset
(e.g. iso-8859-1).  It seems that it is done intentionally
by set-locale-environment as below.

	  ;; If default-enable-multibyte-characters is nil,
	  ;; we are using single-byte characters,
	  ;; so the display table and terminal coding system are irrelevant.
	  (when default-enable-multibyte-characters
	    (set-display-table-and-terminal-coding-system language-name))

I don't know the reason why it does this.  Does anyone
remember that?
