Thank you! I confirm it works.

BTW, I find binding non-essential to t fixes a similar problem caused
by abbreviate/expand-file-name on remote files:

1. save the following text to file A:

;;; -*- coding: utf-8; mode: lisp-data -*-
(("/ssh:192.168.0.100:~/a.txt" . 282))

2. emacs -Q --eval '(setq save-place-file <file A>)' -f save-place-mode
