The problem appears to be that the test uses the secret "unicode-internal"
encoding, which is dependent upon the big/little-endianess of your platform.
I can reproduce your flawed hash exactly on my platform by replacing this
line:

        h.update(u''.join(data).encode('unicode-internal'))

in test_unicodedata.py's test_methods() with this block:

        import array
        xxx = array.array("H", map(ord, u''.join(data)))
        xxx.byteswap()
        h.update(xxx)

When you do this from a shell:

>>> u"A".encode("unicode-internal")
'A\000'
>>>

I bet you get

'\000A'

Right?
