i am already doing (3), and all is working perfectly. bytestring literals are
fine, i'm not sure what this trouble is that you speak of.

i'm sorry this is so confusing, let me try to re-state the problem in as clear
a way as i can.
I have a C++ program, with very well tested unicode support. All logging is
done in utf8. I have conversion routines that work flawlessly, so i can assure
you there is nothing wrong with logging
fair enough. I can provide further proof of strangeness.
here is my latest script: this is saved on disk as a UTF8 encoded file, and
when viewing as UTF8, it shows the correct characters.

i got it!! OMG! so sorry for the confusion, but i learned a lot, and i can
share the result:
the CORRECT code *was* what i had assumed. the Python side has always been
correct (no need to put u in front of strings, it is known that the bytes are
utf8 bytes)
it was my run script function
