Sure.  I admit it's hearsay, but I thought I'd read that because Java Unicode 
is or was underspecified, that there was the possibility of transposition of 
the high-surrogate with the low-surrogate character between Java 
implementations or platforms.

Now I don't exactly write XML dissertations on "Hello Kitty" <g>, so I'm not 
likely to run into this myself, but I was wondering whether Python handles 
surrogate blocks appropriately across platforms and implementations (I guess 
including cpyhton -> Jpython).
