Hi Skip,

Currently, once we are sure the lineobj is a unicode obj we then
get it's internal buffer using:

line = PyUnicode_AsUnicode(lineobj); 

for the purpose of iterating through the line.

is there an opportunity to use:

line = PyBytes_AsString(lineobj); 

(or similar approach if I have quoted an incorrect function) for the
case that we have a bytes object (not Unicode)?
