This falls apart because then f.read() returns objects of type 'unicode' in Python 2, breaking isinstance(..., str) predicates in several places. What I asked for is something else: wrap the version conditional around open() instead of around the conversion from bytes to str. Coding up the (trivial) patch is easier than explaining it in more detail than "pass encoding='utf-8' to open()", so I did just that.
