"the Web" is a big place. Among else, UTF-8 is "The Encoding" (see 
https://encoding.spec.whatwg.org/#the-encoding), and in the definition 
at https://encoding.spec.whatwg.org/#utf-8-decoder, surrogates (whether 
alone or not) produce an error.

So when you speak about the above toxic stuff, please specifically say 
"in JSON" or "in JavaScript".
