# APIs relating to wstr
Since some APIs did not have Py_DEPRECATE until 3.9 (see #65140), it can not be removed in 3.10. I wrote PEP-623 for them.
This issue doesn't about them.
# Deprecated since Python 3.3, and not documented.
In Python 3.3 what's new:
:c:macro:`PyUnicode_GET_LENGTH`
:c:func:`PyUnicode_FromFormat`
:c:macro:`Py_UNICODE_COPY`: use :c:func:`PyUnicode_CopyCharacters` or
:c:func:`PyUnicode_Substring`
:c:func:`PyUnicode_FindChar`
These functions are not documented. But they has Py_DEPRECATED(3.3) from Python 3.6.
Let's remove them in 3.10.
# Deprecated since Python 3.3 with document
Some APIs has document with
.. deprecated:: 3.3 4.0.a) Can we replace 4.0 with 3.10 and remove them in 3.10?
b) Or should we replace 4.0 with 3.11 and wait one more year?

I chose this because they are deprecated since 3.3, and Py_DEPRECATED is used since 3.6.

APIs have /* Py_DEPRECATED(3.3) */
PyUnicode_EncodeDecimal
It is used in PyLong_FromUnicode. Deprecate in 3.10 and remove in 3.12
PyUnicode_TransformDecimalToASCII
While PEP-393 deprecate this too, its document doesn't has
deprecated. Deprecate in 3.10 and remove in 3.12_PyUnicode_ToLowercase, _PyUnicode_ToUppercase
They are not deprecated by PEP-393, but bpo-12736. Deprecate in 3.10 and remove in 3.12.
On the other hand, _PyUnicode_ToTitlecase has Py_DEPRECATED. It can be removed in 3.10.
