I realized:
One can also instruct font-lock to use for non-ascii characters
something like font-lock-warning-face (based on a user option for
enabling this behavior).
And Auctex could do the same.
However this fails with something like the unicode character
'ZERO WIDTH SPACE' (which has fooled me occassionally in the very
context we are discussing here). Is it possible to instruct emacs
to make such "hidden characters" more easily visible, say by using
some display property?
The fontification could also be encapsulated in a minor mode that
one could use for \(Bib\|La\)?TeX files.
Maybe such a minor mode exists already and I am right now
reinventing the wheel?
