[ruby/json] Add `allow_control_characters` parsing option

2025-12-11T10:53:15+00:00

While it's not allowed by the spec, some parsers like Oj do
accept it, and it can be blocking a transition.

Having this feature can help people migrate.

[ruby/json] Add a specific error for unescaped newlines

2025-12-10T10:14:39+00:00

It's the most likely control character so it's worth
giving a better error message for it.

[ruby/json] Fix a regression in parsing of unicode surogate pairs

2025-12-04T08:10:41+00:00

Fix: https://github.com/ruby/json/issues/912

In the case of surogate pairs we consume two backslashes, so
`json_next_backslash` need to ensure it's not sending us back in the
stream.

2025-12-03T02:19:06+00:00

2025-11-22T13:52:26+00:00

We can then pass them to the decoder to save having to parse
the string again.
