Unicode characters. You must pass the address of a :c:type:`Py_UNICODE`

Unicode buffer. Please note that the width of a :c:type:`Py_UNICODE`

for strings where all code points are below 128, 256, or 65536; otherwise, code
points must be below 1114112 (which is the full Unicode range).
:c:type:`Py_UNICODE*` and UTF-8 representations are created on demand and cached
in the Unicode object. The :c:type:`Py_UNICODE*` representation is deprecated
and inefficient.
Due to the transition between the old APIs and the new APIs, Unicode objects
can internally be in two states depending on how they were created:
* "canonical" Unicode objects are all objects created by a non-deprecated
Unicode API. They use the most efficient representation allowed by the
implementation.
* "legacy" Unicode objects have been created through one of the deprecated
APIs (typically :c:func:`PyUnicode_FromUnicode`) and only bear the
:c:type:`Py_UNICODE*` representation; you will have to call
:c:func:`PyUnicode_READY` on them before calling any other API.
UTF-8 representation is created on demand and cached in the Unicode object.
.. note::
The "legacy" Unicode object will be removed in Python 3.12 with deprecated
APIs. All Unicode objects will be "canonical" since then. See :pep:`623`
for more information.
