I have the following code for reading two characters, using the interactive declaration. When I run the interactive function the input character is not being shown after the description string.
(interactive "cOpening delimiter character: \n cClosing delimiter character: \nr")
Reading a character does not echo the character read. This is true for interactive with code c, and for functions such as read-char and read-char-exclusive.
But read-char-from-minibuffer does echo the value read.
(interactive (list (read-char-from-minibuffer "Char: ")))
