+   Encode *input* using escape sequences. Similar to how :func:`repr` on bytes
+   produces escaped byte values. Returns a tuple of the encoded bytes and
+   the length consumed.
+
+.. function:: codecs.escape_decode(input, errors='strict')
+
+   Decode *input* from escape sequences back to the original bytes.
+   Returns a tuple of the decoded bytes and the length consumed.

 .. [#b64] In addition to :term:`bytes-like objects <bytes-like object>`,
    ``'base64_codec'`` also accepts ASCII-only instances of :class:`str` for
