In fact, it's the same as `describe-char'. This command invokes
`what-cursor-position', which invokes `describe-char' eventually.

Cool, I didn't notice its name may be prefixed by its script. It does 
make a lot sense.

However sadly, not all characters do so. For example, a CJK character 
has prefix CJK.
But cjk is not a script name (though there's a script called cjk-misc) 
and it should belong
to `han'.

What's worse is, some characters don't show their names at all, even if 
I assign a font to it.

For example:
             position: 806 of 1031 (78%), column: 1
            character: 😀 (displayed as 😀) (codepoint 128512, 
#o373000, #x1f600)
    preferred charset: unicode (Unicode (ISO10646))
code point in charset: 0x1F600
               syntax: w     which means: word
             category: L:Left-to-right (strong)
          buffer code: #xF0 #x9F #x98 #x80
            file code: #xF0 #x9F #x98 #x80 (encoded by coding system 
utf-8-unix)
              display: no font available

Character code properties: customize what to show
  general-category: Cn (Other, Not Assigned)
  decomposition: (128512) ('😀')
