gpt and gpt_byte are both 439 and that \342 is at byte pos 435

Hmm:
(defun gnus-summary-update-mark (mark type)
(let ((forward (cdr (assq type gnus-summary-mark-positions)))
(inhibit-read-only t))
(re-search-backward "[\n\r]" (point-at-bol) 'move-to-limit)
(when forward
(when (looking-at "\r")
(cl-incf forward))
(when (<= (+ forward (point)) (point-max))
;; Go to the right position on the line.
(goto-char (+ forward (point)))
;; Replace the old mark with the new mark.
(let ((to-insert
(subst-char-in-string
(char-after) mark
(buffer-substring (point) (1+ (point))))))
(delete-region (point) (1+ (point)))
(insert to-insert))
If in an emacs in *scratch* I do
(insert (subst-char-in-string (char-after) ?✓
(buffer-substring-no-properties (point) (1+ (point)))))
that emacs displays several ^@ characters at the end of the buffer,
and then crashes the same way as with Gnus.
Perhaps Iʼm missing something, but isnʼt this just
(delete-region (point) (1+ (point)))
(insert mark)
(that seems to fix the gnus crash for me)
