 Another example that may behave different from what one would expect is this::
 
    >>> s = c_char_p()
-   >>> s.value = "abc def ghi"
+   >>> s.value = b"abc def ghi"
    >>> s.value
-   'abc def ghi'
+   b'abc def ghi'
    >>> s.value is s.value

+   Objects instantiated from :class:`c_char_p` can only have their value set to bytes
+   or integers.
 
 Why is it printing ``False``?  ctypes instances are objects containing a memory
 block plus some :term:`descriptor`\s accessing the contents of the memory.
