Type "M-x find-file-literally RET RET", and then put this at
the file's first line:

//  -*- coding: raw-text -*-

Then save the buffer, kill it, and visit as usual (with 
"C-x C-f" etc.).  You should now see all your escape sequences

The reason for the strange behavior you see is that Emacs by default
interprets the escape sequences as encoded Japanese characters.  The
above line tells it that the text in this file includes some raw
non-printable characters, not encoded non-ASCII text.
