Yes.

Yes:  regardless of platform, always open files used for pickles in
binary mode.  That is, pass "rb" to open() when reading a pickle file,
and "wb" to open() when writing a pickle file.  Then your pickle files
will work unchanged on all platforms.  The same is true of files
containing binary data of any kind (and despite that pickle protocol 0
was called "text mode" for years, it's still binary data).
