Hi Inada-san,
thank you for adding some comments, but they are not really capturing
what I think is missing:
"""
Removing these APIs removes ability to use codec without temporary Unicode.
Codecs can not encode Unicode buffer directly without temporary Unicode
object since Python 3.3. All these APIs creates temporary Unicode object for
now. So removing them doesn't reduce any abilities.
"""
The point is that while the decoders allow going from a C object
to a Python object directly, we are missing a way to do the same
for the encoders, since the Python 3.3 change in the Unicode internals.
At the very least, we should have such APIs for going from wchar_t*
to a Python object.
The alternatives you provide all require creating an intermediate
Python object for this purpose. The APIs you want to remove do that
as well, but that's not the point. The point is to expose the codecs'
decode mechanism which is available in the C code, but currently
not exposed via C APIs, e.g. ucs4lib_utf8_encode().
It would be breaking change, but those APIs in your list could
simply be changed from using Py_UNICODE to using whcar_t instead
and then interface directly to the internal functions we have for
the encoders.
That would keep extensions working after a recompile, since
Py_UNICODE is already a typedef to wchar_t.
Thanks,
