You shouldn't use that at all. If you look at the sources, what SetItemString
does is: create a Python string from the char* and call PyDict_SetItem() to
put the new string in. So it is actually much more efficient to use
PyDict_SetItem() directly in your case.

If you want to temporarily create a char* from a string and you know that the
char content won't be modified, use the PyString_FROM_STRING macro, which just
returns the internal pointer.
