Hi,
In Python 3.2, PyUnicode_Resize() expects a number of Py_UNICODE units, whereas Python 3.3 expects a number of characters.
It is tricky to convert a number of Py_UNICODE units to a number of characters, so it is diffcult to provide a backward compatibility PyUnicode_Resize() function taking a number of Py_UNICODE units in Python 3.3.
Should we rename PyUnicode_Resize() in Python 3.3 to avoid surprising bugs?
The issue only concerns Windows with non-BMP characters, so a very rare use case.
The easiest solution is to do nothing in Python 3.3: the API changed, but it doesn't really matter. Developers just have to be careful on this particular issue (which is not well documented today).
