Hi remi, could you test my patch for PHP_JSON_UNESCAPED_UNICODE option?
The patch adopts JSON_NOTUTF8_SUBSTITUTE and JSON_NOTUTF8_IGNORE options.

I don't think changing the current behavior is a good idea, the reason why I
really prefer some new options.

Hi, thanks nikic and remi.
After several considering, I changed my mind.
I think the behavior of substituting U+FFFD
for ill-formed sequences should be default.
How do you think?
We might need the discussion about the consitency for Escaper API.
htmlspecialchars's ENT_SUBSTITUTE option is adopted
by Symfony and Zend Framework.
https://wiki.php.net/rfc/escaper
Although the behavior breaks 2 test suites, it don't break user's codebases.
A lot of people don't use any option looking in github.

https://github.com/search?l=PHP&q=json_decode&ref=advsearch&type=Code
The same problem can be seen in htmlspecialchars.
https://github.com/search?l=PHP&q=htmlspecialchars&ref=advsearch&type=Code
New options complicate the situation
when using JSON_UNESCAPED_UNICODE option and json_decode.
[two option]
json_encode
JSON_NOTUTF8_SUBSTITUTE
JSON_NOTUTF8_IGNORE
JSON_UNESCAPED_UNICODE | JSON_NOTUTF8_SUBSTITUTE
JSON_UNESCAPED_UNICODE | JSON_NOTUTF8_IGNORE
json_decode
JSON_NOTUTF8_SUBSTITUTE
JSON_NOTUTF8_IGNORE
If JSON_NOTUTF8_SUBSTITUTE is default behavior,
the problem we need to consider is only JSON_NOTUTF8_IGNORE option.
[one option]
json_encode
JSON_NOTUTF8_IGNORE
JSON_UNESCAPED_UNICODE | JSON_NOTUTF8_IGNORE
json_decode
JSON_NOTUTF8_IGNORE

Here is a proposal fo this issue
https://github.com/remicollet/pecl-json-c/commit/5a499a4550d1f29f1f8eeb1b4ca0b01a33c64779
This add 2 new options to json_encode
- JSON_NOTUTF8_SUBSTITUTE (name seems better, at least to me), to replace
not-utf8 char with the replacement char.
- JSON_NOTUTF8_IGNORE to ignore not-utf8 char (remove in escaped mode, keep
without any check in unescaped mode)
------------------------------------------------------------------------

It's currently possible to get a partial output using
JSON_PARTIAL_OUTPUT_ON_ERROR. This will replace invalid UTF8 strings with NULL
though. It probably would make sense to have an alternative option that inserts
the substitution character.
