I have access to a couple Windows Systems (10 Enterprise and 10 Pro) with a
full install
of TeX Live 2021 with current updates.  Both have
"<texlive_2021_install_dir>\bin\win32\albatross.exe"
and the default Windows TL2021 fontconfig setup.   Both work as advertised
(but default Windows terminal
doesn't display UniCode and the output seems to be a fixed width so
truncates the font file pathnames).
On linux the UniCode characters display properly.
