Trigger the same bug....

I want to effectively slice big unicode string. So I decide to use memoryview for that in order to eliminate memory copying.

In [33]: a = array.array('u', 'превед')
In [34]: m = memoryview(a)
In [35]: m[2:]
Out[35]: <memory at 0x7efc98fcc048>
In [36]: m[0]
...
NotImplementedError: memoryview: format w not supported


1. Why format 'w' error if I asked 'u' ?
2. Format 'w' is not listed in https://docs.python.org/3.5/library/array.html
3. What is alternative for fast slicing, like memoryview(bytearray(b'test')), but for unicode ?
