Error during mysqldump on performance_schema.query_cache_info On a production server MariaDB 10.2.13, I actived the plugin query_cache_info.
Suddendly for 5 days, during the daily batch doing dumps (with mysqldump), I have this error :

mysqldump: Couldn't execute 'SELECT /*!40001 SQL_NO_CACHE */ * FROM `QUERY_CACHE_INFO`': Character set '#4294967295' is not a compiled character set and is not specified in the '/usr/share/mysql/charsets/Index.xml' file (22)


I did 

reset query cache


But the problem come back. I don't find the query which could be the problem.
I don't know how resolve this problem.

Do you have any idea ?
Thanks for your help.
Do not dump any tables of performance_schema, information_schema or mysql.  The first two are not 'real' tables, and they cannot be reloaded anyway.

95% of Production servers are not helped by, or even hurt by, turning on the Query cache.  Please elaborate on why you are even attempting to use the QC.
