Right.  *Under the hood* Python uses UCS-2 (which is not exactly the
same thing as UTF-16, by the way) to represent Unicode strings.
However, this is entirely transparent.  To the Python programmer, a
unicode string is just an abstraction of a sequence of code-points.
You don't need to think about UCS-2 at all.  The only times you need
to worry about encodings are when you're encoding unicode characters
to byte strings, or decoding bytes to unicode characters, or opening a
stream in text mode; and in those cases the only encoding that matters
is the external one.
