[issue4618] print_function and unicode_literals don't work together

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

The TypeError("can't write str to text stream") comes from the newline 
written by builtin_print().

Workaround: print(u"foo", end=u"\n", file=StringIO()).
