Problem with Unicode char in Python 3.3.0

[Franck Ditter]

Hi !
I work on MacOS-X Lion and IDLE/Python 3.3.0
I can't get the treble key (U1D11E) !

>>> "\U1D11E"
SyntaxError: (unicode error) 'unicodeescape' codec can't 
decode bytes in position 0-6: end of string in escape sequence

How can I display musical keys ?

Thanks,
