I've never used Python 3, so forgive me if these are naive questions.  
Let's say you had an input stream which contained the following hex 
values:

$ hexdump data
0000000 d7 a8 a3 88 96 95

That's EBCDIC for "Python".  What would I write in Python 3 to read that 
file and print it back out as utf-8 encoded Unicode?

Or, how about a slightly different example:

$ hexdump data
0000000 43 6c 67 75 62 61

That's "Python" in rot-13 encoded ascii.  How would I turn that into 
cleartext Unicode in Python 3?
