If you are going to implement this package, I suggest you to look at
whitespace.el: how it defines where to highlight whitespace character,
how it defines rules for different classes of whitespace.

I don't propose to extend it to visualize suspicious characters
and homoglyphs in addition to whitespace, but really it has very
similar functionality.
