have a look at native2ascii

IIRC it uses sequences like that in its ASCII representation which you
can then convert to any encoding you like.

see http://mindprod.com/jgloss/encoding.html#NATIVE2ASCII

A little finite state machine should handle that fairly easily.
If you find that difficult, I would write one for you.
