Indeed, as the display engine becomes more powerful over time, the
general rule gets broken more and more often.  Unicode is a source of
lots of problems along this way (e.g. with all the barely visible
characters such as the one above, as well as all the "different
character, but displays identically").  There are some libraries that
try to help with this, e.g. uni-confusable (in GNU ELPA), but it's
a hard problem because there is no single "right thing to do".
