So Microsoft claims, but it is not terribly useful.  Currently, on my 
Win 10 system, 'chcp 65001' results in sys.stdout.encoding = 'cp65001', and

for cp in 1200, 1201, 12000, 12001, 65000, 65001, 54936:
     print(chr(cp))

running without the usual exception.  But of the above numbers 
mis-interpreted as codepoints, only 1200 and 1201 print anything other 
than a box with ?, whereas IDLE printed 3 other chars for 3 other 
assigned codepoints. If I change the console font to Lucida Console, 
which I use in IDLE, even chr(1200) gives a box.

After re-reading, I see how I might have inferred that.  Anyway, the OP 
found the solution for his system.
