I would like to point out that UTF-8 is not exactly "Unicode". From what I understand, Unicode is a standard while UTF-8 is like an implementation of that standard (called an encoding). Being able to convert to Unicode (the standard) should mean you are then able to convert to any encoding that supports the Unicode characters used.

As you can see below a string in UTF-8 is actually not Unicode. (decode converts to Unicode, encode converts away from Unicode)

>>> type(u'test'.encode('utf8'))
<type 'str'>
>>> type('test'.decode('utf8'))
<type 'unicode'>
>>> type('test'.encode('utf8'))
<type 'str'>
>>> type(u'test')
<type 'unicode'>
