-   Given a string representing one Unicode character, return an integer
-   representing the Unicode code point of that character.  For example,
+   Return the ordinal value of a character.
+
+   If the argument is a one-character string, return the Unicode code point
+   of that character.  For example,
    ``ord('a')`` returns the integer ``97`` and ``ord('€')`` (Euro sign)
    returns ``8364``.  This is the inverse of :func:`chr`.
 
+   If the argument is a :class:`bytes` or :class:`bytearray` object of
+   length 1, return its single byte value.
