> To make chr() return bytes, I did chr().encode('latin-1') but there is `UnicodeDecodeError: 'ascii' codec can't decode byte 0x80 in position 0: ordinal not in range(128) `error while writing to file. Python 2 also don't have the encoding argument to open which Python 3 has. Looks like need to write a .py file and execute that.

Maybe we can steal pycompat.bytechr of py3. It should work on both Pythons.
