> The I/O stack in Python 3 does not use C FILE streams, and this issue is not related to Windows. TextIOWrapper.tell returns a "cookie" based on the decoder state:

That can big problem when I use serialization if f.tell() is "cookie".

When I serialize it and run program again f.seek() will not works.

I will test it but I think that can be big problem since this behavior is very unclear and non standard (comparing to C++/C#/Java ...).

Maybe it should some method to get right position not "opaque position".
