No. Executing a file containing those exact characters produces a
string containing only '\n' and exec/eval is meant to behave the same
way. The string may not have originated from a file, so the universal
newlines behavior of the io module is irrelevant here -- the parser
must implement its own equivalent processing, and it does.
