I cannot reproduce this on my XP SP3 box, with today's development
sources.  Your Emacs is quite old (2 months ago), but I doubt that
this problem is due to some bug we had at that time.

When you go to those "space characters" and type "C-u C-x =", what
does Emacs say about these two characters in the buffer that it pops
up?
