IPython crashes with message 'UnicodeEncodeError: 'utf-8' codec can't encode characters in position 0-1: surrogates not allowed'

In a Vagrant VM, hosted on a MacBook, run ipython

Then type Option-? (option questionmark)

(That is not what I meant to do. I have no idea if it is reasonable input or not)

The result is this traceback

In [1]: ??
The history saving thread hit an unexpected error (UnicodeEncodeError('utf-8', '\udcc3\udcb7', 0, 2, 'surrogates not allowed')).History will not be written to the database.
