Hi tkeo,

Okay here is an updated version of nlib.zip that should take care of the need to use PYTHONIOENCODING, properly handles kokoro.mobi, and has attempts to fix your other issues although I do not have test1.aw or test4.azw to confirm it works.

Please keep testing it to exercise more code and see if you can break it. I will do the same from my end.

Thanks again for all of your help.
