Package: emacs
Version: 24.0.93


This is a regression against 23.X.

emacs -Q lisp/international/mule-cmds.el

then look for `read-char-by-name', instrument it with C-u C-M-x, then

C-x b <RET>  ; to switch to *scratch*
M-x ucs-insert <RET> <space> <space> <space>  ; until the prompt
<space>  ; at the prompt
