New submission from zsero:
Python 3.3+ works really well when using codepage 65001 under Windows/ConEmu.
Simply starting it with `chcp 65001` allows both printing and inputting of
unicode characters.
However, if any such character is ever entered into the history, the history
functionality breaks from there on.
Error is the following:
```
Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:43:06) [MSC v.1600 32 bit
(Intel)] on win32
