The output of JSON.stringify("\uD800") contains no backslash character,
if you call `utf8_encode(JSON.stringify("\uD800"))` you get an exception
because UTF-8 cannot encode the lone surrogate and `utf8_encode` does
not know it could encode it as `\uD800` without loss of information. If
`JSON.stringify` produced an escape sequence instead, there would be no
problem passing the output to `utf8_encode`.
