The implicit conversion in Python2 only works with ASCII content,
pretty much like what you describe here.
Note that e.g. UTF-16 is not an ASCII super set, but the ASCII
assumption still works:
>>> u'abc'.encode('utf-16-le').decode('ascii')
u'a\x00b\x00c\x00'
Apart from that nit (which can be resolved in most cases by
disallowing 0 bytes), I still believe that the Python2 implicit
conversion between Unicode and 8-bit strings is a very useful
feature in practice.
