Regarding e.g.,
🔮 U+1F52E CRYSTAL BALL

Well doing C-u C-x = on it should really mention "U+1F52E" somewhere, by
default, without needing customization.

P.S., by the way here on Debian it is just a box with numbers in it,
with no package available to fix it.

It does, at least twice.  Or maybe I don't understand what is it that
you are missing in the resulting display.

You need to install a suitable font, I suggest Symbola.

$ grep 1F52E output
code point in charset: 0x1F52E

I want it to say "U+1F52E" somewhere by default.

Yes, and the charset is Unicode (which is where "U" comes from).

I second that.  It might be a small difference to people who are well
acquainted with Emacs coding systems.  However, I believe that Joe
User would prefer the `U+' notation.  (I have a good knowledge of
coding systems, and even I would prefer to see the `U+' prefix :-)

The proper name is CRYSTAL BALL, and it is shown.

This is not about coding systems at all.  The codepoint is shown at
least twice in the display, just without the U+ prefix.

The display produced by that function is already cluttered beyond
hope, so much so that many important details evade you until you
actually read each and every symbol.  Adding the U+ to them (where,
exactly?) would make aa bad situation even worse, for very little
gain.

The proper Unicode name of the character, CRYSTAL BALL, is shown in
the display.

Well, this is a different issue.

I would like to see

  U+1F52E CRYSTAL BALL

Given that the current display is

	       position: 588 of 1015 (58%), column: 2
	      character: 🔮 (displayed as 🔮) (codepoint 128302, #o372456, #x1f52e)
      preferred charset: unicode (Unicode (ISO10646))
  code point in charset: 0x1F52E
		 script: symbol
		 syntax: w 	which means: word
	       category: .:Base
	       to input: type "C-x 8 RET 1f52e" or "C-x 8 RET CRYSTAL BALL"
	    buffer code: #xF0 #x9F #x94 #xAE
	      file code: #xF0 #x9F #x94 #xAE (encoded by coding system utf-8)
		display: by this font (glyph code)
      uniscribe:-outline-Symbola-normal-normal-normal-serif-15-*-*-*-p-*-iso8859-1 (#x1AE4)

  Character code properties: customize what to show
    name: CRYSTAL BALL

With the codepoint shown 3 times above the name, why would you want it
displayed yet another time?  Isn't that highly redundant?

Emacs displays this information for Emacs users.  "C-x =" is a
general-purpose command, not a command intended for learning Unicode
or perusing Unicode blocks.  If someone writes a command for viewing
Unicode blocks, I can understand why U+1F52E should be there.  But
this is not that case.

Is this `codepoint' ever different to the value shown two rows later?

This could be

  code point in charset: U+1F52E

by special-casing Unicode, contrary to other charsets.

For characters from other charsets, yes.

What would be the utility of U+ for Emacs users?  It just makes this
more confusing for people who aren't familiar with the U+nnnn notation
(which obviously excludes me, you, and the OP).  Emacs doesn't accept
that notation in any input mode, and never displays it.

But I'm beginning to repeat myself, so I will shut up on this from now
on.

Also currently saying

            character: 🔮 (displayed as 🔮) (codepoint 128302, #o372456, #x1f52e)
    preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x1F52E

leaves the user still not totally sure the last line really is talking
about the second line or not.

Otherwise instead of saying

    preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x1F52E

It should say

    preferred charset: unicode (Unicode (ISO10646))
code point in preferred charset: 0x1F52E

That way we could be sure it is really talking about unicode.

Fine with me, but we will have to realign the other lines, as they are
all aligned to have the colon in the same column.

I've now removed the "preferred" part from the display, so it says
just "charset", thus the next line is more clearly related to this
one.

Thanks.
