I'm not sure I understand. Why would you make a copy of an immutable
object?
PyUnicode_Copy() can be used to modify a string to create a new string
with the same length. It is used for example by str.upper(),
str.title(), ... (fixup()).
It is also used by str.__getnewargs__(). I am not sure that
str.__getnewargs__() must be a copy of str (s.__getnewargs__() is not x).
As mentionned by Martin, PyUnicode_Copy() is also used to get "an exact"
Unicode object when you have a subtype.
We can maybe make the function private.
