Rather than generating Python code and interpreting it, which, in C++, is fraught with issues of creating the correct syntax for a str token when the text contains certain special characters like double-quote and backslash, the modified code makes call(s) to PyObject_CallObject which takes the C++ string and makes the appropriate conversion itself. The steps in building the Position passed to make_text are also done using c++ objects until the final Python Placement object is needed.
