In it the author talks about how the 'ffl' ligature breaks some string processing.  He claimed that Python 3 doesn't uppercase it correctly--well, it does.  However I discovered that it doesn't reverse it properly.

    x = b'ba\xef\xac\x84e'.decode('utf-8') # "baffle", where "ffl" is a ligature
    print(x) # prints "baffle", with the ligature
    print(x.upper())  # prints "BAFFLE", no ligature, which is fine
    print("".join(reversed(x))) # prints "efflab"

Shouldn't that last line print "elffab"?

If this gets marked as "wontfix" I wouldn't complain.  Just wondering what the Right Thing is to do here.
