Try locale encoding if stdin encoding is ascii....
Try locale encoding if stdin encoding is ascii. Starting the Qt console on Python 3, the kernel's stdin ends up with a .encoding of 'ascii' (whereas on Python 2 it is None). Since most platforms can handle a superset of ASCII, we may as well try locale.getpreferredencoding() in this case.

Add ipy_signals for better ctrl + C processing
r477 """ Advanced signal (e.g. ctrl+C) handling for IPython
So far, this only ignores ctrl + C in IPython file a subprocess
is executing, to get closer to how a "proper" shell behaves.
Other signal processing may be implemented later on.
If _ip.options.verbose is true, show exit status if nonzero
