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.
