Hi Martin,
 Here is the code:
unicodeTest.c

#include<Python.h>

static PyObject *unicode_helper(PyObject *self,PyObject *args){
	PyObject *sampleObj = NULL;
      	Py_UNICODE *sample = NULL;

      if (!PyArg_ParseTuple(args, "O", &sampleObj)){
                return NULL;
      }

	 // Explicitly convert it to unicode and get Py_UNICODE value
      sampleObj = PyUnicode_FromObject(sampleObj);
      sample = PyUnicode_AS_UNICODE(sampleObj);
      wprintf(L"database value after unicode conversion is : %s\n",
sample);
      return Py_BuildValue("");
}

static PyMethodDef funcs[]={{"unicodeTest",(PyCFunction)
unicode_helper,METH_VARARGS,"test ucs2, ucs4"},{NULL}};

void initunicodeTest(void){
	Py_InitModule3("unicodeTest",funcs,"");
}

When i install this unicodeTest on python ucs2 wprintf prints whatever
is passed eg

import unicodeTest
unicodeTest.unicodeTest("hello world")
database value after unicode conversion is : hello world

but it prints the following on ucs4 configured python:
database value after unicode conversion is : h

Abhigyan
