Leaving aside the nuclear option and proselytizing for the moment, the Unicode consortium does helpfully (?) provide a long list of confusable characters
http://www.unicode.org/Public/security/revision-05/confusables.txt and a related technical standard http://www.unicode.org/reports/tr39/ which builds upon a general standard addressing the general security question of spoofing http://www.unicode.org/reports/tr36/ Hmm, writing a text checker to detect potential confusables could actually make for a decent undergraduate thesis project...
