Re: [whatwg/encoding] Consider adding TextEncoder.containsLoneSurrogates() static (#174)

> Web code may not rely upon unpaired surrogates per se, but they definitely rely on the ability for invalid JS strings to roundtrip correctly (e.g. the double input event bug).

Do you have data point other than the double input event bug? Indeed, I think it's better to analyze it as a _bug_ in Chrome's and Firefox's Windows input integration than to analyze it as a fundamental unpaired surrogate dependency of the Web Platform.

Notably, the new (since Firefox 57) CSS OM in Firefox does not round-trip unpaired surrogates, and that hasn't been a problem.
