But IMO this would be a *REALLY* bad idea. There's a standard; we should follow it.

As far as I understand, there¡¯s nothing in Unicode stating higher-level protocols should render control characters, though it may also not recommend not to. In that case, we¡¯re not violating the normative Unicode character properties at all.

I agree. If there is a browser that can't find a word because it has an invisible control character in it, then it should be handled by filing a bug report to the browser maker for its silly usability problem, but it is not in scope for CSS to dictate that.
