In Linux, we get a Nice simple answer for the question:
$ unicode →|sed q
U+2192 RIGHTWARDS ARROW

But in emacs, what-cursor-position gives

          character: → (8594, #o20622, #x2192)
  preferred charset: chinese-big5-1 (Frequently used part (A141-C67E) of Big5 (Chinese traditional))
         code point: 0x2258
             syntax: . 	which means: punctuation
           category: .:Base, c:Chinese, h:Korean, j:Japanese
        buffer code: #xE2 #x86 #x92
          file code: #xE2 #x86 #x92 (encoded by coding system utf-8-unix)
            display: by this font (glyph code)
      x:-eten-fixed-medium-r-normal--16-150-75-75-c-160-big5.eten-0 (#xA1F7)

  Character code properties: customize what to show
    name: RIGHTWARDS ARROW
    old-name: RIGHT ARROW
    general-category: Sm (Symbol, Math)

Why can't you just use
 (format "(%d, #o%o, U+%x, raw-byte)" char char char))
or something?

Why can't you please say "U+..."?

It would be misleading for non-Unicode characters.

JR> It would be misleading for non-Unicode characters.
Well can't emacs know if it is dealing with Unicode or not, and then if
it is, give a U+ somewhere in the output? Don't Unicode characters come
with a "characteristic" signature?

Wait, if emacs is so smart that it can put a U in the modeline, then it
must know it is dealing with Unicode when it so happens to be dealing
with it.
