Hi,
thanks for the pointer, after invoking idle using python.exe, I don't see the crash mentioned in the report:

Python 3.3.0a1 (default, Mar  4 2012, 17:27:59) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> got_ahsa = "\N{GOTHIC LETTER AHSA}"
>>> len(got_ahsa)
1
>>> got_ahsa.encode("unicode-escape")
b'\\U00010330'
>>> got_ahsa

>>> print(got_ahsa)

>>> 


I just get empty line as "answer" but no crash.

The console indeed contains the traceback with the error I expected

   vbr
