It does (more or less) choosing 7bit legacy fonts without even European
accented letters
so basically disables all luatex Unicode support, in which case you may as
well use pdflatex.

especially I would not use the version you used:

This is LuaTeX, Version beta-0.80.0

there were many changes in luatex before the release of luatex version 1
(which has been stable for some years, the luatex team already working on
its successor) The current version has banner

This is LuaTeX, Version 1.13.2

I would have thought the main feature of a bibliography tool would be to
handle the names of people cited.
If you silently change names without warning, is that really usable other
than for testing?
How do you choose close ascii for Greek or Cyrillic or Chinese names? And
even for accented latin alphabet
you can't drop the accents without changing people's names, or introducing
errors into titles of papers?
