Moreover, there are \201 (not \202) characters before each Polish letter
when restoring session using desktop.el, even if file is _not_ under
version control.

Simple example: I wrote the following contents to the file pltest.txt
%% pltest.txt begins here
ąćęłńóśżź
ĄĆĘŁŃÓŚŻŹ

abcdefghijklmnopqrstuvwxyz
ABCDEFGHIJKLMNOPQRSTUVWXYZ
%% pltest.txt ends here.

Then I used M-x desktop-save and quit Emacs. When I run Emacs in the
directory where .emacs.desktop was saved, the screen contains (pasted via
xclipboard):
%% pltest.txt begins here
ąćęłńóśżź
ĄĆĘŁŃÓŚŻŹ

abcdefghijklmnopqrstuvwxyz
ABCDEFGHIJKLMNOPQRSTUVWXYZ
%% pltest.txt ends here.

It _looks_ like this:
%% pltest.txt begins here
\201ą\201ć\201ę\201ł\201ń\201ó\201ś\201ż\201ź
\201Ą\201Ć\201Ę\201Ł\201Ń\201Ó\201Ś\201Ż\201Ź
abcdefghijklmnopqrstuvwxyz
ABCDEFGHIJKLMNOPQRSTUVWXYZ
%% pltest.txt ends here.

The .emacs.desktop contains
%% .emacs.desktop begins here

My .emacs file contains (among others) the following lines:
(desktop-load-default)
(desktop-read)
(standard-display-european t)
(if running-xemacs
    (progn
      (turn-on-font-lock)

  (progn
    (global-font-lock-mode t)
    (setq font-lock-support-mode 'lazy-lock-mode)))
(setq font-lock-maximum-decoration t)


Have you any suggestions to what is wrong?
