[Jython-bugs] [issue2784] memoryview accepts unicode strings as input

[Bernie H. <re...@bu...>]

New submission from Bernie Hackett <be...@10...>:

In CPython 2 and 3 and PyPy 2 and 3 memoryview only accepts objects that implement the buffer protocol. unicode / python3 str don't implement the buffer protocol so memoryview doesn't accept them, but memoryview in Jython does.
