Another point to mention is that the reason for this difference in behaviour is because cpython uses UCS-2 for character representation, whereas java (and thus jython) uses UTF-16.

"\udeee" *is* a valid code point in UCS-2: it just doesn't represent anything. This is why cpython does not complain.

Jython's behaviour is arguably more correct in this case. 

Also cpython, because it uses UCS-2, cannot represent characters outside the "Basic Multilingual Plane", but jython, because it uses UTF-16, can.
