Can you try using a font with emacs which does not compose the x and overbar? >> I assume the mswindows and applemac systems dont pull in harfbuzz? > No, the Windows build does use HarfBuzz. Whatever is doing the visual composition of x + overbar (when emacs is explicitly asked not to do it by turning auto-composition-mode off) - it isn't harfbuzz. It happens on an emacs (--without-all) which links to freetype without harfbuzz/cairo (and even when emacs isn't using m17n-lib) Very puzzling.
