Python 2.7.5 bug

Если type(url) == unicode и в data есть байты со значениями больше 0x7F(128-255), urllib2 пытается декодировать данные в какую-то, только ему известную кодировку

>>> req = urllib2.Request(unicode('http://site.ru/test'), data='\xff'); urllib2.urlopen(req)

Traceback (most recent call last):
