This note incorrectly stated that "Base64 has an expansion factor of 6
to 4" (it is actually 4 to 3). It was decided to remove the note.

.. versionadded:: 3.4
-.. note::
- Both Base85 and Ascii85 have an expansion factor of 5 to 4 (5 Base85 or
- Ascii85 characters can encode 4 binary bytes), while the better-known
- Base64 has an expansion factor of 6 to 4. They are therefore more
- efficient when space expensive. They differ by details such as the
- character map used for encoding.
