In unicode land, an "encoding" is a method of representing
unicode data in an external format. So you encode unicode
data in order to send it into the outside world, and you
decode it in order to turn it back into unicode data.

It'll be easier to get right in py3k, because bytes will only have
a decode() method and str will only have an encode() method.

Unicode objects don't *have* an encoding. UCS2 is not an encoding,
it's an internal storage format. You're not supposed to need to know
or care about it, and it could be different between different
Python builds.

It's the safest assumption. Python is refusing the temptation
to guess the encoding of anything outside the range 0-127 if you
don't tell it.
