I'd say use `backquote' in Lisp settings (indeed, even an
Elisp function) ... for everything else, use the (new) name.

Uhm, what other aliases would that be? And if any, where are
they stored in Emacs?
BTW, check this out:
;; -*- lexical-binding: t -*-

;; this file:
;; https://dataswamp.org/~incal/emacs-init/char.el
(defun what-char (&optional pos)
(interactive "P")
(let*((position (or (and (numberp pos) pos)
(point) ))
(kill pos)
(char (char-after position)) )
(when char
(let*((name (get-char-code-property char 'name))
(old-name (get-char-code-property char 'old-name))
(msg (if (and name old-name)
(format "%s (old: %s)" name old-name)
(or name old-name) ))
(msg-dc (when (stringp msg) (downcase msg))) )
(when msg-dc
(prog1 msg-dc
(when kill (kill-new msg-dc))
(message "%s (at point: %d)" msg-dc position) ))))))
;; (what-char) ; "space"
;; (what-char 754) ; "right parenthesis (old: closing parenthesis)"
;; C-u 754 M-x what-char RET ; same, but also killed
;; C-u M-x what-char RET* (C-y) ; asterisk is yanked
