C-u C-x 8 RET GREEK CAPITAL LETTER PSI RET
C-b
C-u C-x =

Buffer *Help* says this, for field `to input':

  type "C-x 8 RET HEX-CODEPOINT" or "C-x 8 RET NAME"

It should instead be able to say something like this:

  type "C-x 8 RET 0x03A8" or "C-x 8 RET GREEK CAPITAL LETTER PSI"

Both of these pieces of information are shown in the same buffer
*Help*.  It seems a bit silly to tell a user to type HEX-CODEPOINT or
NAME, when these are known when *Help* is created.

	Please consider the patch MIMEd.

I see no need to tell users to type at least 4 hex digits: "C-x 8 RET"
accepts even one digit.  So I think we should use %x here.

> +                           char (get-char-code-property char 'name)))))))

Not every Unicode codepoint has a name, so get-char-code-property
could return nil.  E.g., try with any codepoint between zero and #x1f,
inclusive.  When that happens, we should try 'old-name' instead, and
if that returns nil as well (try #x99, for example), I think the "by
name" part should be omitted from the output of describe-char.

Thanks.

	(I’ve suspected something like that, but didn’t check.)

	Please consider the revised patch MIMEd.

	* lisp/descr-text.el (describe-char): Show the exact C-x 8 RET
	invocation instead of a template.  (Bug#20522)

	It was also requested in bug#20499 that a specific C-x 8
	(iso-transl) sequence is shown.  Yet I believe that deserves a
	separate patch.
