As Mark Tolonen pointed out earlier in this thread, in Python 3 the
practicality apparently beat purity in this aspect:
Python 3.1.1 (r311:74483, Aug 17 2009, 17:02:12) [MSC v.1500 32 bit
(Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> goth_urus_1 = '\U0001033f'
>>> list(goth_urus_1)
['\ud800', '\udf3f']
>>> len(goth_urus_1)
2
>>> ord(goth_urus_1)
66367
>>> goth_urus_2 = chr(66367)
>>> len(goth_urus_2)
2
>>> import unicodedata
>>> unicodedata.name(goth_urus_1)
'GOTHIC LETTER URUS'
>>> goth_urus_3 = unicodedata.lookup("GOTHIC LETTER URUS")
>>> goth_urus_4 = "\N{GOTHIC LETTER URUS}"
>>> goth_urus_1 == goth_urus_2 == goth_urus_3 == goth_urus_4
True
>>>
As for the behaviour in python 2.x, it's probably good enough, that
the surrogates aren't prohibited and the eventually needed behaviour
can be easily added via custom functions.
