I think the bad reordering in XHTML files is so blatantly obvious that
any reasonable person will see where the text needs overrides right
away.

That said, it shouldn't be hard to implement such a feature: one needs
to move through the displayed glyphs and look for discontinuities in
buffer position corresponding to the characters.  Then put an overlay
over characters thus detected.
