Aaaah.

Of course, it is there for debugging temporarily.

Sure, it is frantic attempt to make it work.

(defun replace-line (from to)
  (let* ((start (line-beginning-position))
         (end (line-end-position)))
    (save-excursion
      (replace-string from to nil start end))))

[ ]   M-: (replace-line "[ ]" "[X]") works well
[ ]   M-: (replace-line "[ ]" "[✔]") works well
[✔]   M-: (replace-line "[✔]" "[ ]") works well

Combining it is not working.

Do you have solution? Not hair style please.
