.. note::
``a2b_*`` functions accept Unicode strings containing only ASCII characters.
- Other functions only accept bytes and bytes-compatible objects (such as
- bytearray objects and other objects implementing the buffer API).
+ Other functions only accept :term:`bytes-like object`\ s (such as
+ :class:`bytes`, :class:`bytearray` and other objects that support the buffer
+ protocol).
.. versionchanged:: 3.3
ASCII-only unicode strings are now accepted by the ``a2b_*`` functions.
