[Python-Dev] Unicode strings as filenames

I'm sure that is not what Marc meant.  I think he simply meant a conversion
function that would return the filename as either byte or Unicode.  Get your
arg from PyArg_ParseTuple, and convert it with this function.

Have I missed it all these years, or should we define a PyArg_ParseTuple
format that takes a "void **" and a function pointer to a type conversion
function?

Mark.
