When json_escape changed[1] to return a -1 in the case of
a character that didn't match the character set, json_unescape_to_string
assumed the -1 meant out of memory and just looped with more
memory.
Problem 1 - json_escape needs to return a different code
so that the different between charset incompatibility and out
of memory needs to occur. This enables json_escape_to_string
to handle the it correctly (ignore and fail seems the best
option).
Problem 2 - JSON histograms need to support character with
where the column json min/maximum value aren't a character
set represented by a single byte.
Problem 2 was previously hidden as ? was a result of the conversion.
As JSON histograms can relate to columns when have an explict
character set, use that and fall back to bin which was the
previous default for non-string columns.
Replaces -1/-2 constants and handling with JSON_ERROR_ILLEGAL_SYMBOL /
JSON_ERROR_OUT_OF_SPACE defines.

MariaDB: The innovative open source database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:
https://mariadb.com/kb/en/mariadb-vs-mysql-features/
https://mariadb.com/kb/en/mariadb-versus-mysql-compatibility/

Getting the code, building it and testing it
Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
Help
