% Second part of workaround for odd XeTeX/babel-french behaviour
% https://github.com/plk/biblatex/issues/979
% fix by Ulrike Fischer
% https://tex.stackexchange.com/a/544914/.
% The first bit lives in biblatex.sty.
% At some point we may want to consider providing a
% blx-unicode-xetex and a blx-unicode-lualatex
% both loading a blx-unicode-generic.
% For now this test is enough.
