Fatal error Invalid datetime format when rebuilding search index

Hi, Merry Christmas

I have update a system to OJS 3.3.0-13 and execute the tool for reindexing all the system.

php tools/rebuildSearchIndex.php

The tool indexed correctly the first journal but in the second one it throws an error

Indexando “Colombia forestal” … PHP Fatal error: Uncaught PDOException: SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect string value: ‘\xF0\x9D\x91\x92\xF0\x9D…’ for column revistas.submission_search_keyword_list.keyword_text at row 1 in /var/www/html/lib/pkp/lib/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOStatement.php:115

Database and tables are Collation is utf8_general_ci and character_set_database is utf8

What could it be? Regards
