New submission from STINNER Victor <victor.stin...@haypocalc.com>:
The curses module (only since Python 3.3), locale.strcoll(), locale.strxfrm(),
time.strftime() and imp.NullImporter() (only on Windows) accept embedded null
characters, whereas they convert the Unicode string to a wide character
(wchar_t*) string.
The problem is that the null character truncates the string. Example:
>>> locale.strxfrm('a')
'a'
>>> locale.strxfrm('a\0b')
'a'
Attached patch fixes these functions. I wrote the patch for Python 3.3.
