(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.

I'd be happy to install such a patch, yes. Please send it along.

Indeed, placing them before would make sense.

Indeed, this version has various problems. E.g. as a user, I'd often
have trouble figuring out which chars goes with which name.
I agree that the annotation mechanism would deserve improvement.

FWIW, Icicles has had that feature for quite a while.
The attached screenshot shows also what happens when cycling:
*Completions* mode line shows the char with its code point.
,----
| icicle-read-char-by-name is a compiled Lisp function.
|
| (icicle-read-char-by-name PROMPT &optional NAMES)
|
| Read a character by its Unicode name or hex number string.
| Display PROMPT and read a string that represents a character by its
| Unicode property `name' or `old-name'. Return the char as a number.
|
| You can use completion against the Unicode name of the character.
|
| In Icicle mode:
|
| * The character itself is displayed next to its name, even though it
| is not part of the completion candidate. WYSIWYG.
|
| * When you cycle among candidates, the current character and its
| Unicode code point are shown in the mode line (provided user option
| `icicle-help-in-mode-line-delay' is greater than zero.)
|
| If you use a dedicated `*Completions*' frame, then the font used in
| `*Completions*' is the same as the frame from which you invoked
| completion.
|
| If you use library `doremi-frm.el' then you can increase the font size
| for `*Completions*' dynamically using `C-x -'.
|
| As an alternative to completing the Unicode name, you can input a
| number for the Unicode code point: a hexidecimal number or a number in
| hash notation: #o21430 for octal, #x2318 for hex, or #10r8984 for
| decimal.
|
| Non-nil optional arg NAMES is an alist of names to use in place of the
| value returned by `icicle-ucs-names'. It must have the same form as
| such a return value: (CHAR-NAME . CHAR-CODE).
