R devel - Apr 2018 - embeded R application on Windows prints broken character.

The issue was reported to me for?https://github.com/randy3k/rtichoke/issues/50
which is a python program which embeds R and provides a interface to R.

With R 3.5,?for reason which i don't understand, when I typed
`"a"` in the console
STDOUT got `"\x02\xff\xfea\x03\xff\xfe"`?with the extra escaped
characters.

I notice that `\x02\xff\xfe` and `\x03\xff\xfe` are encoding related byte marks.
A clear solution is to filter the escaped characters, but I want to understand
what
changes are causing it happens. It didn?t happen for R 3.4.

The maintainer (randy3k, oh that's you) of that python package has
apparently fixed it:
