I've fixed this for a bunch more of these characters, but there are endless numbers of Unicode characters that can be abused to do things like this.

Solution: don't do this.

This is not a bug. It's possible to post a post with any other Unicode character, why not these? We don't have automated systems (yet) to patrol content: we rely on humans to do that. This is an example of bad content that people shouldn't post and that people will patrol. Posting an empty-looking post is no worse (arguably is better) than posting a post full of nonsense.

Yeah, so this is a bug. See this to see how it's done.

Basically it involves copying invisible CSS characters into an answer or question.
