I and l also look identical in many fonts. So you already have this problem in ascii. (To say nothing of all the non-printing characters!)
If your security relies on a person being able to tell the difference between two characters controlled by an attacker your security is bad.
The problem is when you can register "apple.com" with the Cryillic A, fooling many.
The I l issue is caused by fonts, not by ASCII.
