What's the reverse of Py_BuildValue("u#" ?

[sndive at gmail.com]

How could I get the pointer to and the length of ucs2 array out of a
PyObject representing
a string? Something that works whether PyObject string is in unicode or
not.

Also could I replace a sequence

    if(PyBool_Check(obj)) {
...
    }
    if(PyString_Check(obj)) { // would this be true for any string
type?
...
    }
    if(PyFloat_Check(obj)) {
...

with a switch?

Thank you!
