You would need an even longer text that explains that a quoted-string that contains characters that are not in the definition of token -- excepted for the initial quote and the last quote -- is invalid.  You would also need to explain that, contrary to the rule for a quoted-string, the string is case-insensitive.  And you still have to explain that the string needs to be normalized before copy in the JSON document.

So many words.
