New submission from Christian Heimes:
The array module is using a different typecode for unicode array
depending on UCS2 or UCS4:
#define Py_UNICODE_SIZE 4
#if Py_UNICODE_SIZE >= 4
#define Py_UNICODE_WIDE
#endif
#ifdef Py_UNICODE_WIDE
#define PyArr_UNI 'w'
#define PyArr_UNISTR "w"
#else
#define PyArr_UNI 'u'
#define PyArr_UNISTR "u"
#endif
It's causing a bunch of unit test to fail which depend on 'u' as the
type code for an unicode array. I don't see the benefit from specifying
an alternative typecode for wide unicode arrays. It may be useful to
have an additional typecode that fails for UCS-2 builds.
My patch keeps 'u' in every build and adds 'w' as an alias for 'u' in
UCS-4 builds only. It also introduces the new module variable typecodes
which is a unicode string containing all valid typecodes.
