[issue6345] extra characters displayed when writing to sys.stdout.buffer

[Mark Tolonen]

New submission from Mark Tolonen <metolone at hotmail.com>:

According to Issue xxxx, sys.stdout.buffer is the binary stream 
underlying stdout.  I see the following behavior on 3.0.1 and 3.1rc2 
when writing to a console window:

Python 3.1rc2 (r31rc2:73414, Jun 13 2009, 16:43:15) [MSC v.1500 32 bit 
(Intel)]
on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> 
sys.stdout.buffer.write('hello\u200bworld'.encode('cp437','replace'))
hello?world11

Notice the extra '11' at the end of the string.
