[New-bugs-announce] [issue13452] PyUnicode_EncodeDecimal: reject error handlers different than strict

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

Error handling of PyUnicode_EncodeDecimal() is broken by design. The caller cannot know the size of the output buffer because each error handler produce a variable output, whereas the caller has to allocate 
this buffer and it is not possible to specify the size of the output buffer.

I propose to raise a ValueError if the error handler is different than "strict" and do this change in Python 2.7, 3.2 and 3.3.

In Python 2.7 code base, PyUnicode_EncodeDecimal() is always called with 
errors=NULL. In Python 3.x, the function is no more called.

Attached patch is for Python 3.2.

See also the issue #13093.
