Package: emacs
Version: 24.0.95
mode-line-mule-info contains this:
(propertize
"%z" 'help-echo [...]
(format "Buffer coding system %s\nmouse-1: describe coding system"
(if enable-multibyte-characters
(concat "(multi-byte): "
(symbol-name buffer-file-coding-system))
(concat "(unibyte): "
(symbol-name buffer-file-coding-system))))
The intent is obviously that you see (multibyte) in the mode-line
tooltip in a multibyte buffer, and (unibyte) otherwise.
However, you will never see the unibyte tooltip, because:
(set-buffer-multibyte nil)
(format-mode-line "%z")
-> ""
ie, the empty string, so there is nowhere for the help-echo to display.
Compare with "-" in multibyte buffers.
If it returned " " instead of "", you would see the tooltip.

Sounds reasonable; fixed in trunk.
