The problem here is that defining what characters are "similar" enough to be homographs is a very fuzzy concept. Glyphs that may look similar on a 1600x1200 display on my laptop may not look similar when the *same exact* 1600x1200 is being displayed on the 21" monitor hanging off my docking station. Also, the point size in use may matter - that macron that's easily visible at 15pt may be invisible at 11pt. Bitmap and outline fonts will have different behaviors in this regard, and anti-aliasing adds another twist to the equations.... And even if you program all *that* sort of knowledge in, there's no way in the near future that the software will know if I'm wearing my contacts or if I'm wearing my glasses, and if I'm wearing contacts, if I happen to have my reading glasses handy.....
