The title lis little misleading: "Note that the base character does not need to be an emoji – the treatment of variation selectors is the same with regular characters. It’s just more fun with emoji."
Using this approach with non-emoji characters makes it more stealth and even more disturbing.
I don't see this as all that disturbing. A detector for it wouldn't be hard to write (variant on something that doesn't actually have variants, flag it!), it seems to me it could be useful for signing things.
