how to show ascii number of a character

how to show ascii number of a character

[Zimmen Gnauh]

   Is there any emacs function that can show a the ascii number of a
character? i.e. you enter a character, and it shows a number. For
example, enter character D, it will show 68, or in octal, binary or
other forms.

Add this to your ~/.emacs:

(defun zg-char-to-ascii ()
  "Show the ASCII number of a character."
  (interactive)
  (message (number-to-string
            (aref (read-from-minibuffer "Type a character: ") 0))))

... and do M-x zg-char-to-ascii.

(defun show-ascii ()
    (interactive)
    (message "The code of the character at point is: %d" (char-after)))

In emacs, a character is an integer. 

If you  place the  point at  an ASCII character,  you'll get  an ASCII
code, but otherwise, it depends  on the encoding currently used in the
buffer.

It is not clear for me what your purpose is, but what about C-u C-x =
?

Put the cursor on the character and type C-x =
