The following errata report has been submitted for RFC8259,
"The JavaScript Object Notation (JSON) Data Interchange Format".

You may review the report below and at:

Type: Technical
Reported by: Vasiliy Faronov <vfaronov@gmail.com>

Section: 12

Original Text
JSON is a subset of JavaScript

Corrected Text
JSON is nearly a subset of JavaScript

JSON is not a subset of JavaScript: there are syntactically valid JSON texts that are not syntactically valid JavaScript. Namely, JSON strings can contain unescaped U+2028 LINE SEPARATOR or U+2029 PARAGRAPH SEPARATOR characters, while JavaScript string literals cannot. Thus, a sequence of characters U+0022 U+2028 U+0022 matches this RFC's 'string' production, but does not match ECMA-262's 'Expression' production.

This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
can log in to change the status and edit the report, if necessary.
