Sorry, maybe I wasn't clear. My point was about the fact that since the escapes and the actual characters don't have the same length, and since printing a docstring doesn't rewrap it, docstrings wrapped with M-q in the source will look wrong after rendering.

Given this (wrapped with M-q):

    (defun aaa ()
      "AAAA.
    \N{ARROW POINTING DOWNWARDS THEN CURVING LEFTWARDS} is not the
    same as \N{ARROW POINTING RIGHTWARDS THEN CURVING DOWNWARDS}.")

The rendering will be

    aaa is a Lisp function.

    (aaa)

    AAAA.
    ⤶ is not the
    same as ⤵.
