Comment:

 @hwgehring sorry, but your claim that "Unicode-escaped text is only valid
 JSON in certain exceptional cases" is a misreading of the RFC you quoted.

 From https://tools.ietf.org/html/rfc8259#section-7:

 > Any character may be escaped.  If the character is in the Basic
 Multilingual Plane (U+0000 through U+FFFF), then it may be represented as
 a six-character sequence ... Alternatively, there are two-character
 sequence escape representations of some popular characters.

 So even the string `"\u0048\u0065\u006c\u006c\u006f"` is perfectly valid
 JSON.  Proof:
 https://jsonlint.com/?json=%22\u0048\u0065\u006c\u006c\u006f%22

 Again, if this is an issue for you, it means the library or technique you
 are using to parse JSON is incorrect.
