(My NIC card went down during earlier sent.  Apologies if it results in
duplicate bug)

It will be wonderful if ucs-insert shows the characters visually in the
completion buffer.

Here is a proof-of-concept.  Install an annotation function. 

    (setq completion-extra-properties
          (list :annotation-function 'annotate-ucs-names))

    (defun annotate-ucs-names (name)
      (format "(%s)" (char-to-string (cdr (assoc-string name (ucs-names) t)))))

M-x insert-char RET will give screenshot 1.  Note the presence of
characters visually next to char names.  I would have wised to place the
the glyphs come before the description.

Now let us install a small /hack/ to minibuffer as shown below. The
result is as shown in screenshot 2, which I would much prefer.
(Ofcourse, the insertion itself wouldn't work)

Following two things emerge from this experiment.

    1. Annotation may go infront of the candidate.
    2. Annotation may provide a substitution for visual feedback etc etc.
