-

-valid JSON per the official spec: https://tools.ietf.org/html/rfc8259
-
-The resulting JSON will always be the same length as the input and it will
-include all of the same line breaks at matching offsets. This is to ensure
-the result can be later processed by a external parser and that that
-parser will report messages or errors with the correct offsets.
