I can't see why anything has been killed, here.

Sure, this is almost the same as CPython: writing a Unicode object to
a file will encode it with the default encoding. Writing a byte string
to a file will write the bytes.

Since Jython uses Java strings both for Unicode and byte strings, it
has an "extra" byte in each element of a byte string, which is not
written to the file.

In any case, you have to encode Unicode data with an explicit encoding
before writing them to files.

I think you don't understand it properly. Why is it disasterous?
