single: integer
single: Unicode
The items of a string object are Unicode code units. A Unicode code
unit is represented by a string object of one item and can hold either
a 16-bit or 32-bit value representing a Unicode ordinal (the maximum
value for the ordinal is given in ``sys.maxunicode``, and depends on
how Python is configured at compile time). Surrogate pairs may be
present in the Unicode object, and will be reported as two separate
items. The built-in functions :func:`chr` and :func:`ord` convert
between code units and nonnegative integers representing the Unicode
ordinals as defined in the Unicode Standard 3.0. Conversion from and to
other encodings are possible through the string method :meth:`encode`.
A string is a sequence of values that represent Unicode codepoints.
All the codepoints in range ``U+0000 - U+10FFFF`` can be represented
in a string. Python doesn't have a :c:type:`chr` type, and
every characters in the string is represented as a string object
with length ``1``. The built-in function :func:`chr` converts a
character to its codepoint (as an integer); :func:`ord` converts
an integer in range ``0 - 10FFFF`` to the corresponding character.
:meth:`str.encode` can be used to convert a :class:`str` to
:class:`bytes` using the given encoding, and :meth:`bytes.decode` can
be used to achieve the opposite.
