ipython UnicodeEncodeError when providing unicode char to "os.read(0,1)"

I recently started playing with IPython and found a case where it exists with an "UnicodeEncodeError" error. I confirmed the issue exist on the latest version. See how to reproduce / error bellow.

Note that I do expect an error to be raised by 'os.read()', however I don't think IPython itself should exit.

If you suspect this is an IPython bug, please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at ipython-dev@python.org

You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
    %config Application.verbose_crash=True
