Hi Sanjeet and others,

sorry for late answer, I hope to be more responsive now.

I created a ticket where we can discuss changes for Python Scripting
Library [1]. I uploaded your patch, so please upload your future
patches there, you can upload final patches to your github (I suggest
to structure your repo in some way and use more descriptive names than
Look at my patch, hopefully it makes sense.

We discussed further changes in this library regarding unicode/bytes
handling with Vaclav and collected ideas here [2]. Basically, we need
to adjust many functions to accept and return unicode ('str' in
Python3), otherwise the functions won't behave as expected when used
by Python 3 users. For Popen wrapper functions (read_command,
run_command, ...) we suggest to use new encoding parameter (similar to
Popen in Python3.6) allowing to switch the behavior for fine control,
with using unicode by default (to work as expected by Python 3 users).
There will be problems because it's not garbage in garbage out as it
used to be, so something encoded on Windows won't be read correctly on
Linux. However this is our current idea, we can discuss it further.

So, Sanjeet, let me know if it makes sense to you and try to implement
the changes where necessary (starting with core.py). It would be good
to write more tests during the process.
